Experiences of Patients with Unilateral Vocal Fold Paralysis: A Mixed-Methods Study of the Insider's Perspective.

OBJECTIVE: Unilateral vocal fold paralysis (UVFP) is often characterized by severe dysphonia and has a significant impact on a patient's communication in daily and vocational situations. Having a better understanding of how UVFP influences quality of life and patient experiences can help improve patient-centered care in this population. Therefore, the purpose of this study was to explore the lived experiences of patients with UVFP. METHODS: Twenty-five adults with UVFP (age range: 39-84years) participated in the study. Quantitative data were collected from 22 participants, using the Voice Handicap Index (VHI), Dysphonia Severity Index (DSI), and Acoustic Voice Quality Index (AVQI). Qualitative data were collected from 25 individual semistructured interviews, which were recorded, transcribed, and analyzed with the software program NVivo. The interviews were coded using an inductive thematic approach. RESULTS: Quantitative results showed a mean DSI of - 1.6, mean AVQI of 3.80, and mean VHI of 45.8 in the participant group. A statistically significant, moderate (positive) correlation was found between VHI and time after onset (in years). From the qualitative analysis of the interviews, four main themes were identified: emotional impact, psychosocial impact, physical complaints, and coping strategies. Voice problems caused by UVFP generally had a negative impact on patients' emotional and psychological well-being, with considerable effects on participation, self-identity, and professional activity. Participants demonstrated a combination of problem-focused and emotion-focused coping strategies to accommodate to these issues. Half of the participant group also showed avoidance as a coping style. VHI scores were significantly higher in participants who reported experiencing current emotional and participation problems due to UVFP, and who had not yet accepted their new voice. CONCLUSION: The themes from this study emphasize the importance of focused anamnesis and emotive counseling in practice, with specific attention to the psychosocial and emotional impact of UVFP.

Clinical Experiences of Voice Therapists in the Rehabilitation of Pediatric Vocal Fold Nodules.

OBJECTIVES: The purpose of this study was to identify common clinical practices and experiences of voice therapists regarding the treatment of pediatric vocal fold nodules (VFNs) in Flanders, Belgium. STUDY DESIGN: Observational survey study. METHODS: A 38-item online survey was completed by 35 voice therapists (32 females, 3 males) with experience in treating pediatric VFNs. Demographic characteristics, occupational characteristics, educational characteristics, therapy content, therapy delivery model, and experience of the voice therapist were explored. Experiences of voice therapists were measured using visual analog scales (score 0-100). An extensive descriptive analysis was performed using IBM SPSS version 28. RESULTS: The majority of voice therapists (93.9%) provide a combination of direct and indirect therapy techniques when treating children with VFNs. The most commonly used direct techniques are breathing exercises (84.4%), semioccluded vocal tract exercises (71.9%) with a clear preference for resonance tube in water and resonant voice therapy, and relaxation exercises (65.6%). On average, Flemish voice therapists provide 24.80 (SD: 11.5, range: 10-50) half-hour sessions, usually at a frequency of once a week. No respondents had experience with intensive therapy or group therapy in the treatment of pediatric VFNs. Regarding the experience of voice therapists with treating VFNs in children, respondents give a mean score of 77.28 (SD: 13.7, range: 50-100) on a scale of 0 (negative experience) to 100 (positive experience). Furthermore, 96.2% of voice therapists experience difficulties during treatment and 40% feel there are not enough targeted training opportunities on the topic of pediatric VFNs. CONCLUSION: Flemish voice therapists generally feel comfortable treating pediatric VFNs. They usually provide a combination of direct and indirect therapy and use a wide range of different direct therapy techniques. However, there is still some need to organize more focused and tailor-made training initiatives.

Do Adult Naïve Listeners Perceive Differences in Speech Before and After Therapy for Cleft Palate Speech Disorders? A Reliability Study of Perceptual Speech Ratings.

PURPOSE: This study compared the interrater reliability of adult naïve listeners' perceptual assessments of different speech variables in children with a cleft palate with or without a cleft lip (CP ± L). In addition, the study investigated whether the listeners were able to perceive differences in these speech variables before and after speech therapy for cleft palate speech disorders. METHOD: Thirty-four speech samples of 14 children with a CP ± L (14 samples collected immediately before 10 hr of speech intervention, 14 samples collected immediately after speech intervention, and six randomly selected samples that were duplicated to assess intrarater reliability) were perceptually assessed by 26 adult naïve listeners. The listening panel consisted of nine men and 17 women (age range: 18-51 years). The speech variables included speech understandability, speech acceptability, hypernasality, hyponasality, nasal airflow, and articulation, which were assessed on a visual analog scale. Furthermore, the need for speech therapy was assessed. RESULTS: Good to very good interrater reliability was observed for the naïve listeners' ratings of all speech variables. A significant time effect was found for the pre- and postevolution of the speech variables "speech understandability," "speech acceptability," "nasal airflow," and "articulation." This time effect indicates an improvement of these variables postintervention. According to the naïve listeners, children were less in need of additional speech therapy after the 10-hr intervention period compared to assessments before this intervention period. CONCLUSIONS: Adult naïve listeners perceptually identified an improvement in different speech variables after 10 hr of cleft palate speech therapy. These findings confirm previous assessments of expert speech-language pathologists and suggest that speech improvements after cleft palate speech therapy can also be perceived by communication partners outside the therapy room. Perceptual ratings of naïve listeners can, thus, be used to add life-situation significance to the assessments of experts. Future research could include both expert raters and caregivers or relatives of children with a CP ± L in listening panels, as previous knowledge on craniofacial anomalies may lead to different results.

Attitudes of Teachers toward Multilingualism, Heritage Language Maintenance, and Second Language Learning at School.

INTRODUCTION: Providing an adapted language input in a multicultural classroom is often challenging to educators. Teachers are frequently the parents' first contacts for language counseling and educational support, and therefore, they may influence the language exposure not only in the classroom but at home as well. This study aimed to investigate the cognitive, emotional, and behavioral attitudes of teachers toward multilingualism in Flanders. The effects of contextual teacher- and school-related properties on the attitudes of teachers were also considered. METHODS: An online survey questioning the cognitive, emotional, and behavioral attitudes of teachers was developed and distributed to all schools in Flanders. 710 preschool, primary, and secondary teachers completed the questionnaire. RESULTS: The results showed rather positive attitudes toward heritage language maintenance and multilingualism. However, there are still some misconceptions about multilingual language learning strategies. Teachers are interested in extra training, as they find it hard to use the languages of their pupils as a resource in their teaching practice. DISCUSSION: Teachers mostly consider multilingualism an added value. Supplementary training and extra advice given by speech-language therapists could be helpful to inform teachers about the importance of their students' proficiency in the heritage language and could give teachers insight into the principles of second language acquisition.

Treatment Outcomes of Interdisciplinary Care on Speech and Health-Related Quality of Life Outcomes in Adults With Cleft Palate.

PURPOSE: Individuals born with a cleft palate with or without a cleft lip (CP ± L) often experience functional, aesthetic, and psychosocial consequences well into adulthood. This study aimed to investigate outcomes of speech and health-related quality of life (HRQoL) in adults with a CP ± L who received interdisciplinary cleft care at the Ghent University Hospital using valid, reliable, and condition-specific instruments. METHOD: Thirteen Belgian Dutch-speaking participants with a CP ± L with a mean age of 25.4 years (SD = 5.1, range: 20-33 years) and an age- and gender-matched control group of 13 participants without a CP ± L with a mean age of 25.2 years (SD = 4.8, range: 20-32 years) were included in this study. Speech characteristics were evaluated perceptually and instrumentally. HRQoL was assessed through standardized patient-reported outcome measures. Outcomes were compared with those of the control group and to normative data where available. RESULTS: Participants with a CP ± L in this sample demonstrated significantly lower speech acceptability (p < .001) and higher rates of hypernasality (p = .015) and nasal turbulence (p = .005) than the control group. They showed significantly higher satisfaction with appearance of the cleft scar compared with norms of adults with a CP ± L (p = .047). No other differences in speech characteristics, sociodemographics, or HRQoL were found between participants with and without a CP ± L. CONCLUSIONS: The reduced speech acceptability and the presence of resonance and nasal airflow disorders may indicate the need for standardized long-term outcome measurement and interdisciplinary follow-up for speech characteristics and velopharyngeal insufficiency in young and middle adulthood in future clinical practice. Additional research is necessary to further substantiate these findings and to determine predictors for these continuing complications in adults with a CP ± L.

Vocabulary Diversity in Personal Narratives Produced in Response to the Global TALES Protocol in Dutch-Speaking Students with and without Dyslexia.

INTRODUCTION: This study examines whether there are differences in expressive vocabulary between participants with and without dyslexia in personal narratives in response to the Global TALES protocol. METHODS: 22 monolingual Dutch-speaking participants aged 11-16 with dyslexia and 22 age and gender-matched peers without dyslexia were assessed on measures of decoding, reading comprehension, and spelling of words, pseudowords, verbs, and sentences. The participants also produced personal narratives in response to the six prompts contained in the Global TALES protocol. We analyzed the personal narratives for expressive vocabulary and counted the total number of different words (TNDW). RESULTS: The study revealed a significant relationship between TNDW and reading comprehension (r = 0.45, p = 0.002, BF10 = 17.70), spelling words (r = 0.42, p = 0.005, BF10 = 8.93), and spelling and writing conventions in sentences (r = 0.37, p = 0.016, BF10 = 3.11). The Global TALES protocol was successful in eliciting personal narratives in the Dutch-speaking participants with and without dyslexia. Participants with dyslexia used fewer different words (M = 192.27, SD = 64.37; 95% CI: [151.84-232.71]) compared to peers without dyslexia (M = 265.50, SD = 116.28; 95% CI: [225.06-305.93]; F(1, 42) = 6.68; p = 0.013; η2 = 0.14). When we compared the probability of models, Bayesian factors revealed moderate evidence for group differences in TNDW (BF = 3.94). CONCLUSION: Our findings indicate that older school-age participants with dyslexia may lag behind their peers in expressive vocabulary in a personal narrative discourse task that is relevant to everyday functioning. The results of this study highlight the relationship between expressive vocabulary and reading comprehension and the importance of the assessment of spoken language skills in children with dyslexia. Reading problems might lead to less advanced spoken language, which in turn may negatively affect the expressive vocabulary growth in individuals with dyslexia.

Effect of a Group-Based Narrative Language Training in Typically Developing Turkish-Dutch Children.

INTRODUCTION: Due to the heterogeneity in language trajectories and differences in language exposure, a lot of bilingual children could use extra support for the acquisition of the school language to reduce the risk of language problems and learning difficulties. Enhancing bilingual children's narrative abilities in the school language could be an efficient approach to ameliorate the general school language abilities as well. Therefore, this study aimed to investigate whether a narrative intervention could improve both general and narrative school language abilities of typically developing bilingual (Turkish-Dutch) children. METHODS: Nineteen Turkish-Dutch bilingual children (6 - 9.9 years) were enrolled in this single-arm early efficacy study. The intervention procedure was administered in the school language (Dutch) and based on a test-teach-retest principle with two baseline measurements. At baseline 1, the expressive, receptive and narrative language abilities were determined. The second baseline measurement consisted of a second measurement of the narrative abilities. Subsequently, a weekly one-hour group-based intervention was implemented during 10 sessions. After the intervention phase, the expressive, receptive and narrative language abilities were tested again. RESULTS: After the intervention, the children produced significantly more story structure elements compared to both baseline measurements. No significant differences were found for microstructure narrative measures. The participants had significantly higher scores on the expressive and receptive language measurements post intervention. DISCUSSION/CONCLUSION: These findings suggest that the intervention could be an efficient approach to stimulate the second language development of bilingual children.

The Occurrence of Laryngeal Pathologies in a Treatment-Seeking Pediatric Population.

OBJECTIVES: The purpose of this study was to 1) describe the age- and sex-specific occurrence of laryngeal pathologies in a treatment-seeking pediatric population in the voice unit of Ghent University Hospital, Belgium, and 2) describe this population in terms of vocal parameters, vocal complaints, influencing factors, and treatment history and recommendation. STUDY DESIGN: Retrospective, observational study. METHODS: All patient records were analyzed for children (0-18 years) who consulted the ear, nose, and throat department of Ghent University Hospital for the first time between July 2015 and June 2021 with complaints of dysphonia. In total, 103 children (66 males, 37 females) with a mean age of 10.01 years (SD: 3.4, range 3.93-17.96) were included in this study. Laryngeal pathology was diagnosed using a flexible videolaryngo(strobo)scopy. The influence of age and sex on laryngeal etiology (organic/functional voice disorder) was examined using a Welch-modified t test and a Fisher's exact test, respectively. RESULTS: Organic lesions were observed in 77.7% of the participants, with vocal fold nodules (VFNs) being the most common diagnosis (66.0%). A functional voice disorder was diagnosed in 22.3% of the children. Children with a functional voice disorder are significantly older than children with an organic voice disorder. There was no statistically significant difference between males and females in laryngeal etiology. Mean dysphonia severity index was -2.7 (SD: 3.2, range -9.3 to +3.7), the mean acoustic voice quality index 4.70 (SD: 1.5, range 2.35-8.27), and the mean pediatric voice handicap index 29.8 (SD: 13.6, range 5-60). The occurrence of vocal misuse was mentioned in 80.6% of the patient records. CONCLUSION: Organic voice disorders, especially VFNs, are predominant in treatment-seeking children with dysphonia. Functional voice disorders become more common with increasing age during childhood. A disordered vocal quality, reduced vocal capabilities and reduced voice-related quality of life were found.

A protocol for a randomized-controlled trial to investigate the effect of infant sign training on the speech-language development in young children born with cleft palate.

BACKGROUND: Children born with a cleft palate with or without cleft lip (CP ± L) are known to be at risk for speech-language disorders that impact educational and social-emotional growth. It is hypothesized that speech-language intervention delivered before the age of 3 years could decrease the impact of CP ± L on speech-language development. Infant sign training in combination with verbal input expands the natural communication of young children including multimodal speech-language input (i.e., verbal and manual input) via caregivers who act as co-therapists. AIMS: To determine the effectiveness of infant sign training in 1-year-old children with CP ± L by comparing different interventions. METHODS & PROCEDURES: This is a two-centre, randomized, parallel-group, longitudinal, controlled trial. Children are randomized to either an infant sign training group (IST group), a verbal training group (VT group) or no intervention control group (C group). Caregivers of children who are assigned to the IST group or VT group will participate in three caregiver training meetings to practise knowledge and skills to stimulate speech-language development. Outcome measures include a combination of questionnaires, language tests and observational analyses of communicative acts. OUTCOMES & RESULTS: It is hypothesized that speech-language development of children with CP ± L will benefit more from IST compared with VT and no intervention. Additionally, the number and quality of communicative acts of both children and caregivers are expected to be higher after IST. CONCLUSIONS & IMPLICATIONS: This project will contribute to the development of evidence-based clinical practice guidelines regarding early speech-language intervention in children with CP ± L under the age of 3 years. WHAT THIS PAPER ADDS: What is already known on the subject Children with CP ± L are known to be at risk for speech-language delays that impact educational and social emotional growth. Given the limited scientific prove of the impact of early speech-language intervention, no standardized clinical practice guidelines are available yet for children with CP ± L under the age of 3 years. Early intervention in this population mostly focuses on improving verbal input via caregivers or professionals without including a multimodal language input. A growing scientific interest has been seen in the use of infant signs to support speech-language development and caregiver-child interaction in typically developing children and children with developmental delays. What this study adds to existing knowledge No evidence is yet available for the effectiveness and feasibility of early intervention based on infant sign training in combination with verbal input to improve speech-language skills in young children with CP ± L. The current project will investigate the effect of infant sign training on the speech-language development in this population. Outcome measures are compared with those of two control groups: verbal training only and no intervention. It is hypothesized that infant signs may support the intelligibility of verbal utterances produced by children with CP ± L. Improving children's intelligibility may increase the opportunities for these children to engage in early, frequent and high-quality interactions with their caregivers resulting in a richer social and linguistic environment. As a result, infant sign training may result in better speech-language skills compared with the control interventions. What are the potential or actual clinical implications of this work? If providing early intervention based on infant sign training is effective, there is the potential for improved speech-language outcomes in early childhood, resulting in increased speech intelligibility, increased well-being of the child and family and less need for speech-language therapy on the long-term. This project will contribute to the development of evidence-based clinical practice guidelines regarding early speech-language intervention in children with CP ± L under the age of 3 years.

Clinical Experiences of Speech-Language Pathologists in the Rehabilitation of Unilateral Vocal Fold Paralysis.

PURPOSE: Unilateral vocal fold paralysis (UVFP) is a neurological voice disorder that is often first treated by a speech-language pathologist (SLP). In literature, little consensus is found regarding voice therapy onset, duration, frequency, and content. The aim of the current study is to investigate the clinical practice of SLPs for treatment of UVFP regarding diagnostics and treatment characteristics. Additionally, the study examined the personal experiences of SLPs regarding UVFP care. METHOD: An online survey was completed by 37 respondents, all SLPs with experience in treating UVFP. Demographic characteristics, experiences with voice assessments and treatment modalities were examined. Lastly, experiences and opinions of SLPs on evidence-based practice and their own clinical practice were surveyed. RESULTS: Almost all respondents used a multidimensional voice assessment with findings from laryngovideostroboscopy to assess UVFP. Laryngeal electromyography is not yet integrated in regular clinical practices. The most commonly used vocal techniques were resonant voice exercises, laryngeal manipulation, semioccluded vocal tract exercises (SOVTEs), vocal hygiene, and Vocal Function Exercises, with SOVTEs most often considered effective. A total of 75% of the respondents feel confident treating UVFP, and 87.6% believe it is important to stay updated on evidence-based practice. Variation in therapy timing and dosage was observed, and 48.4% of SLPs usually started early voice therapy within 4 weeks after UVFP onset. CONCLUSION: Flemish SLPs generally feel confident treating UVFP patients and show interest in improving evidence-based practice. Initiatives to train clinicians further in UVFP care and encouraging SLPs to provide practice-based evidence will enhance the knowledge base for evidence-based practice in UFVP.

Telepractice in the diagnosis and treatment of pediatric speech-language disorders: The opinions and experiences of speech-language pathologists.

PURPOSE: This prospective cross-sectional study aimed to investigate the opinions and experiences with telepractice (TP) of Dutch-speaking speech-language pathologists (SLPs) living in the Dutch-speaking part of Belgium (Flanders). This study will help to optimize care for children with speech-language disorders as we will gain more insight into the experienced barriers and facilitators while using TP for assessing and treating these disorders. METHOD: Twenty-nine Dutch-speaking speech-language pathologists living in Flanders (age category 20-30 years: n = 16/29, 55.2%, 31-40 years: n = 10/29, 34.2%, 41-50 years: n = 2/29, 6.9%, 51-60 years: n = 1/29, 3.4%) were recruited through the social media. An online questionnaire was developed based on the available literature and administered to the SLPs. To compare the opinions and experiences of SLPs with TP, χ2 tests or Fisher's exact tests were used. RESULTS: The study showed a statistically significant association between years of clinical experience of SLPs and their opinion that TP does not provide more options in a clinical setting compared to face-to-face contact. SLPs who had expertise in multiple domains experienced significantly more added value of TP during the corona pandemic than SLPs who had expertise in only one specific domain. Additionally, SLPs who worked in a private practice indicated significantly more difficulties in developing a therapeutic relationship due to a lack of personal contact than SLPs who worked in other settings. 51.7% (15/29) of the SLPs experienced technical barriers using TP. CONCLUSION: Expertise in multiple domains of pediatric speech-language therapy resulted in experiencing more added value of TP during the corona pandemic, possibly because of the experience of multiple different and simultaneous advantages of TP in several domains. Additionally, SLPs in a private practice experienced more difficulties in developing a therapeutic relationship due to a lack of personal contact with their clients. This is in contrast to hospitals where children are often seen for a shorter period. Hence, there may be less chance of a negative perception of relationships with clients. Another conclusion is that treatment drop-out was not larger using TP compared to face-to-face therapy. However, SLPs experienced that the use of TP was not promoted/encouraged by their employer possibly because of technical barriers. It is hoped that the findings of this study will help SLPs and policymakers overthrow existing barriers and make telepractice a substantial, effective, and efficient service delivery model.

Immediate effects of a semi-occluded water-resistance ventilation mask on vocal outcomes in women with dysphonia.

INTRODUCTION: Semi-occluded vocal tract exercises (SOVTEs) are frequently used exercises in voice therapy. An important shortcoming to most SOVTEs is the inability to include continuous speech in these exercises. A variation of water-resistance therapy (WRT), during which a patient phonates through a resonance tube ending in water, was developed to include continuous speech: the semi-occluded water resistance ventilation mask (SOVM-WR). The current study investigated the immediate effects of this innovative technique on vocal outcomes of women with dysphonia. METHODS: A pretest-posttest randomized controlled trial was performed. Twenty female participants were randomly assigned to the experimental SOVM-WR group or the WRT (control) group. A blinded multidimensional voice assessment was conducted before and after a 30-minute therapy session with the assigned technique. RESULTS: No significant changes were found in acoustic or auditory-perceptual vocal outcomes in either of the groups, except for a significant increase in lowest frequency in both groups. Patient-reported outcomes (PROMs) showed significant improvements of vocal comfort, vocal effort, and voice quality in both groups, and participants indicated that they would use the techniques at home. CONCLUSIONS: The similar results of the SOVM-WR to WRT and promising PROMs confirm its suitability as an alternative to the latter technique. Potential reasons for a lack of improvement of objective and auditory-perceptual vocal outcomes are vocal fatigue, tube dimensions and immersion, and the small sample size. Large-scale and longitudinal research is needed to examine whether the SOVM-WR has a higher transfer to spontaneous speech than WRT after a full therapy program.

'Sometimes I feel sad': A qualitative study on children's perceptions with cleft palate speech and language therapy.

BACKGROUND: Evidence-based speech therapy involves the integration of (1) the scientific evidence for therapy with (2) the perspectives of clinicians concerning therapy and (3) the perspectives of patients about therapy. The cleft literature has already paid attention to the first two cornerstones of evidence-based speech therapy. Much less is known about how children perceive cleft speech therapy. AIMS: The purpose of the current qualitative study was to investigate the perceptions, emotions and expectations of Flemish-speaking Dutch children with a cleft (lip and) palate (CP ± L), aged 5-12 years, with regard to the speech therapy they receive. In this study, a focus was made on speech therapy to eliminate compensatory cleft speech errors. METHODS & PROCEDURES: Six children with a CP ± L, aged between 5 and 12 years, were included in this study. Child-friendly semi-structured interviews were conducted using a participatory, art-based qualitative approach. This means that the 'play and puppets technique' and 'draw-write and photo-elicitation technique' were used to guide the children through the interviews. Data derived from these interviews were analysed using an inductive thematic approach. Trustworthiness of the data was achieved by applying researcher triangulation, negative case analysis and an audit trail. OUTCOMES & RESULTS: Analyses of the interviews revealed three major themes of importance to the children: (1) treatment values, (2) treatment practices and (3) treatment outcomes. Each theme was divided into different subthemes. The theme 'treatment values' consisted of the subthemes expectations and emotions around therapy and interference with daily living. Information flow, therapy content, confirmation and rewards, parents' attendance, therapy intensity, and homework were subthemes of the major theme 'treatment practices'. The theme 'treatment outcomes' was divided into two subthemes, namely speech improvement and peers' reactions. CONCLUSIONS & IMPLICATIONS: Most children had positive attitudes towards speech therapy: it was 'something they liked' and 'something fun'. If children had negative attitudes they were related to having a fear of making mistakes during therapy. Children had clear expectations of the purpose of speech therapy. Speech therapy should 'help' improve their speech and make it more understandable to others. The children in this sample made some suggestions to decrease the experienced burden related to speech therapy. The results of this study will help to better tailor speech therapy programmes to the needs and experiences of children with a CP ± L. WHAT THIS PAPER ADDS: What is already known on the subject Evidence-based speech therapy involves the integration of (1) the scientific evidence for therapy with (2) the perspectives of clinicians concerning therapy and (3) the perspectives of patients and their families about therapy. The cleft literature has already paid attention to the first two cornerstones of evidence-based speech therapy. Different studies investigated the perspectives of SLPs and parents with regard to cleft palate speech therapy. However, much less is known about the children's own experiences with and perceptions around this speech therapy. What this study adds to existing knowledge This study used a qualitative research design to investigate the perceptions, emotions and expectations of children with a cleft (lip and) palate, aged 5-12 years, with regard to the speech therapy they receive. Speech therapy needed to focus on the elimination of compensatory speech errors. This study provides knowledge on the speech therapy-related experiences of children with a cleft palate. What are the potential or actual clinical implications of this work? Children in this sample made some concrete suggestions to decrease the experienced burden related to cleft speech therapy, for example, integration of school work during therapy sessions and practising on the level of spontaneous speech. The results of this study help us to better tailor speech therapy programmes to the needs and experiences of children with a CP ± L.

Achieving the next level in cleft speech intervention: A protocol of a randomized sham-controlled trial to provide guidelines for a personalized approach in children with cleft palate.

BACKGROUND: Compensatory cleft speech disorders can severely impact speech understandability and speech acceptability. Speech intervention is necessary to eliminate these disorders. There is, however, currently no consensus on the most effective speech therapy approach to eliminate the different subtypes of compensatory cleft speech disorders. AIMS: To compare the immediate, short- and long-term effects of three well-defined speech intervention approaches (i.e., a motor-phonetic approach, a linguistic-phonological approach and a combined phonetic-phonological approach) on the speech and health-related quality of life (HRQoL) in Belgian Dutch-speaking children with cleft palate with or without cleft lip (CP±L) and different subtypes of compensatory speech disorders (i.e., anterior oral cleft speech characteristics (CSCs), posterior oral CSCs or non-oral CSCs). Besides, the perceived acceptability of these three speech intervention approaches will be investigated from the perspectives of caregivers and children with a CP±L. METHODS & PROCEDURES: A two-centre longitudinal randomized sham-controlled trial was used. Children were randomly assigned to one of the three intervention programmes and received 10 h of speech intervention divided over 2 weeks. Block randomization was used, stratified by age and gender. Primary outcome measures included perceptual speech outcomes. Secondary outcome measures included patient-reported outcomes. OUTCOMES & RESULTS: The results of this trial will provide speech-language pathologists evidence-based guidelines to better tailor intervention approaches to the specific needs of a child with a defined compensatory speech disorder. WHAT THIS PAPER ADDS: What is already known on this subject Speech therapy approaches to address cleft palate speech disorders are broadly divided into two categories: motor-phonetic interventions and linguistic-phonological interventions. Some limited evidence demonstrated the positive effects of these approaches in eliminating compensatory cleft speech disorders. Different studies have reported inter-individual variation, suggesting that one child may benefit more from a particular intervention approach than the other child. Perhaps this variation can be attributed to the specific subtype of compensatory speech disorder (i.e., anterior oral CSC, posterior oral CSC or non-oral CSC). What this paper adds to existing knowledge This paper describes a randomized sham-controlled trial that compared the immediate, short- and long-term effects of three well-defined speech intervention approaches (i.e., a motor-phonetic approach, a linguistic-phonological approach and a combined phonetic-phonological approach) on the speech and HRQoL in Belgian Dutch-speaking children with CP±L and different subtypes of compensatory cleft speech disorders (i.e., anterior oral CSCs, posterior oral CSCs or non-oral CSCs) measured by perceptual and psychosocial outcome measures. Besides, the experienced acceptability of these three speech intervention approaches were investigated from the perspectives of caregivers and children. What are the potential or actual clinical implications of this work? This project provides evidence-based knowledge on patient-tailored cleft speech intervention considering both scientific evidence and the perspectives of caregivers and children. The results aid SLPs in better tailoring intervention approaches to the needs of a child with a specific type of compensatory cleft speech disorder.

Immediate effects of straw phonation in air or water on the laryngeal function and configuration of female speech-language pathology students visualised with strobovideolaryngoscopy: A randomised controlled trial.

BACKGROUND: A promising way to obtain vocal economy and efficiency is by semi-occluding the vocal tract while phonating. Current knowledge about the immediate effects of semi-occluded vocal tract (SOVT) phonation on the laryngeal function and configuration is based mainly on computer modelling or excised larynges studies. In in vivo SOVT studies, electroglottography (EGG) has been the most commonly used laryngeal outcome, showing contradictory results between studies. Therefore, exploring these aspects by direct visualisation of the human larynx during SOVT phonation using strobovideolaryngoscopy (SVL) is needed. AIMS: The aim of this study was to investigate and compare the immediate effects of straw phonation (SP) in air, SP in 2 cm water, and SP in 5 cm water (with stirring straws), on the laryngeal function and configuration of a homogeneous group of vocally healthy female speech-language pathology students, visualised with flexible SVL. METHODS & PROCEDURE: A randomised controlled trial was used. Fifty-two female speech-language pathology students (mean age: 18.7 years, SD: 0.6) were assigned randomly to one of three experimental groups or a control group: (1) SP in air, (2) SP in 2 cm water, (3) SP in 5 cm water or (4) [u] phonation with similar soft onset and slightly pursed lips as in SP but without a straw (control group). The participants underwent flexible SVL during habitual [u] phonation, followed by the specific SOVT exercise of their group assignment. All video samples were evaluated randomly and blindly by two experienced investigators using the Voice-Vibratory Assessment with Laryngeal Imaging (VALI) rating form, first independently and then by consensus. OUTCOME & RESULTS: Compared to habitual phonation, the vibrational amplitude decreased during SP in 5 cm water and SP in 2 cm water, being more prominent in the first, more flow-resistant exercise. The mucosal wave also decreased during SP in 5 cm water. The anteroposterior (AP) supraglottic compression similarly increased during SP in air, SP in 2 cm water, and SP in 5 cm water. Further, a rise in mediolateral (ML) compression and a decrease in phase symmetry and regularity were found during SP in 2 cm water. A similar decrease in regularity was observed during SP in 5 cm water. CONCLUSIONS & IMPLICATIONS: Both SP in air and SP in water cause positive immediate laryngeal effects for voice training opportunities. More AP supraglottic activity found during each SP exercise might indicate epilarynx narrowing, an economic phenomenon associated with SOVT. Immersing the straw in water additionally diminished the vibrational amplitude, lowering vocal fold impact stress and risk for phonotrauma during the exercise. The decreased regularity of the vibrational cycles during SP in water might be due to the varying back pressure created by the water bubbling. The impact of SP in water on ML supraglottic compression needs further investigation. WHAT THIS PAPER ADDS: What is already known on the subject A promising way to obtain vocal economy and efficiency is by semi-occluding the vocal tract while phonating. Current knowledge about the immediate effects of semi-occluded vocal tract (SOVT) phonation on the laryngeal function and configuration is based mainly on computer modelling or excised larynges studies.

Therefore, exploring these aspects by direct visualisation of the human larynx during SOVT phonation using strobovideolaryngoscopy (SVL) is needed. What this paper adds to existing knowledge Group results of the current study generally support earlier computer modelling and in vivo studies, strengthening the current SOVT knowledge. Both SP in air and SP in water cause positive immediate laryngeal effects for voice training opportunities. More anteroposterior (AP) supraglottic activity found during each SP exercise might indicate epilarynx narrowing, an economic phenomenon associated with SOVT. Immersing the straw in water additionally diminished the vibrational amplitude, lowering vocal fold impact stress and risk for phonotrauma during the exercise. The decreased regularity of the vibrational cycles during SP in water might be due to the varying back pressure created by the water bubbling. The impact of SP in water on ML supraglottic compression needs further investigation. What are the potential or actual clinical implications of this work? Current results support that both SP in air and SP in water can be useful exercises in voice training. SP in water has shown the additional gain of lowering the vibrational amplitude during the exercise, hence supporting its appropriateness for vocal warm-ups by minimising vocal fold impact stress and the risk of phonotrauma. In the future, large-scale randomised controlled trials in other subgroups of voice users, including dysphonic patients, are needed to support evidence-based practice. SVL can facilitate the search for individualised training and therapy approaches.

Self-reported Vocal Demands, Perceptions, and Knowledge of Occupational Voice Users in South Africa.

OBJECTIVES: The study aimed to describe daily vocal demands, perceptions and knowledge as reported by occupational voice users. STUDY DESIGN: A descriptive, cross-sectional research design was employed. METHODS: A survey on vocal demands, perceptions and knowledge was distributed to 102 occupational voice users via a snowball sampling technique. RESULTS: Slightly more than half of the participants (55%) reported using their voice for work 36.5 hours a week on average (SD = 15.5, range: 33-40). Participants reported that, on average, their daily voice use is 6.3 hours (SD = 2.7) for work and the majority (81%) reported a decrease in voice quality after work; Three-quarters (75%) also reported vocal fatigue at the end of day. Approximately one-third (33%) reported being exposed to environments where they are expected to shout, scream or cheer loudly. More than half of the participants (61%) reported that they have previously received vocal health education but 40% reported that they felt this training was insufficient. High vocal demands are significantly correlated to an increase in perceived vocal handicap rs = 0.242; (P = 0.018), tiredness of voice rs = 0.270; (P = 0.008), physical discomfort rs = 0.217; (P = 0.038) as well as how occupational voice users experience improvement of symptoms with rest rs = -0.356 (P < 0.001). Other risk factors highlighted by occupational voice users are the ingestion of liquid caffeine, alcohol, and carbonated drinks, smoking or the presence of chronic cough, chronic laryngitis, and gastroesophageal reflux disease. CONCLUSIONS: Occupational voice users are subjected to high daily vocal demands that can be seen to be linked to vocal fatigue, changes in voice quality and vocal symptoms experienced. It is essential that occupational voice users as well as treating clinicians are aware of certain significant predictors of both vocal handicap and vocal fatigue. These findings provide insights for developing strategies for training and cultivating vocal health consciousness and preventive voice care initiatives that focus on occupational voice users in South Africa.

Longitudinal Vocal Outcomes and Voice-Related Quality of Life After Selective Bilateral Laryngeal Reinnervation: A Case Study.

PURPOSE: Bilateral vocal fold paralysis (BVFP) is a severe disorder that can result in respiratory, swallowing, and voice-related problems. Most surgical treatments do not restore laryngeal function and often need to compromise voice quality to preserve respiratory function. Laryngeal reinnervation (LR) may offer a solution to this problem, but literature on longitudinal outcomes of this procedure is scarce. This study aims to report the longitudinal vocal outcomes of BVFP after LR and subsequent voice therapy. METHOD: The case of a 23-year-old man with BVFP after a traumatic dissection of both recurrent laryngeal nerves is described. Selective bilateral LR of both adductors and abductors was performed 5 months after the onset of BVFP. Voice therapy was provided after the LR procedure. Multidimensional voice assessments, including acoustic, perceptual, and patient-reported outcome measures (PROMs), were conducted 2, 5, 6.5, 8, and 31 months after LR. RESULTS: An improvement of vocal capabilities and voice quality was noticed 6.5 months after LR, after 4.5 months of voice therapy, with normative values after 2.5 years. PROMs showed an improvement of voice-related quality of life, but some limitations to activities of daily living were still present. Inspiratory arytenoid abduction was not observed on laryngeal videostroboscopic findings in this patient, but tracheostomy was not required. CONCLUSIONS: Voice therapy after LR helps establish healthy and efficient voice use without increasing compensatory hyperfunctional behavior. More research is needed to examine potential merits of voice therapy in the rehabilitation of vocal and respiratory functions after LR.

Peer attitudes towards adolescents with speech disorders due to cleft lip and palate.

BACKGROUND AND AIMS: Individuals with speech disorders are often judged more negatively than peers without speech disorders. A limited number of studies examined the attitudes of adolescents toward peers with speech disorders due to a cleft lip with or without a cleft of the palate (CL ± P). Therefore, the aim of the present study was to investigate the attitudes of peers toward the speech of adolescents with CL ± P. METHOD: Seventy-eight typically developing adolescents (15-18 years, 26 boys, 52 girls) judged audio and audiovisual samples of two adolescents with CL ± P based on three attitude components, i.e., cognitive, affective, and behavioral. The degree of speech intelligibility was also scored by their peers. The study investigated whether the three attitudes were determined by speech intelligibility or appearance of an individual with CL ± P. Furthermore, the influence of knowing someone with a cleft, the age, and gender of the listeners on their attitudes were explored. RESULTS: A significantly positive correlation was found between the speech intelligibility percentage and the three different attitude components: more positive attitudes were observed when the speech intelligibility of the speaker was higher. A different appearance due to a cleft lip does not lead to more negative attitudes. Furthermore, boys seem to have more negative attitudes toward individuals with CL ± P compared to girls. CONCLUSION: This study provided additional evidence that peers show more negative attitudes toward adolescents with less intelligible speech due to CL ± P. Intervention should focus on changing the cognitive, affective, and behavioral attitudes of peers in a more positive direction and remove the stigma of patients with a cleft. Further research is needed to verify these results.

Intonation Parameters in Gender Diverse People.

OBJECTIVES/HYPOTHESIS: Although intonation is often addressed in speech training for gender diverse individuals, the relationship between intonation and femininity/masculinity ratings remains unclear. The aim of this study was to examine differences in intonation parameters in gender diverse individuals. Moreover, the relationship between acoustic intonation parameters and femininity/masculinity ratings was investigated. METHODS: Speech samples of semistructured speech were elicited from cisgender (cis) (107 ciswomen, 104 cis men), transgender (trans) (19 trans women, 10 trans men), and non-binary (n = 11) individuals using a prosody protocol. An objective acoustic analysis was performed to compare intonation parameters (upward/downward/flat intonation shift, general and final intonation shift, general fundamental frequency range, fundamental frequency variation index) between groups. In addition, a listening experiment was conducted, consisting of a cis and gender diverse listening panel (n = 41). The listeners were asked to rate the femininity/masculinity of speech samples (n = 57) using a visual analogue scale. Correlational analyses were used to examine the relationship between intonation parameters and femininity/masculinity ratings. RESULTS: Similarity was found in the intonation parameters of participants with a similar gender identity. In non-binary speakers, no significant differences in acoustic intonation parameters were found between these speakers and the cisgender speakers. In addition, no significant correlations were found between the acoustic intonation parameters and the femininity/masculinity ratings in the groups with cis men, cis women, and non-binary participants. However, moderate to strong significant correlations were found between acoustic intonation parameters and femininity/masculinity ratings in the trans participants. CONCLUSIONS: Intonation is a "speech marker" that distinguishes between groups with a different gender identity. No relationship was observed between intonation and femininity/masculinity ratings for cisgender and non-binary speakers. However, the significant relationship between these parameters for transgender participants (trans men and trans women) provides evidence for intonation exercises in gender affirming voice, speech, and communication training, and therefore contribute to evidence-based intonation training in transgender persons.
