RESUMEN
PURPOSE: The present study investigates the perception of vowel nasality in French-speaking children with cochlear implants (CIs; CI group) and children with typical hearing (TH; TH group) aged 4-12 years. By investigating the vocalic nasality feature in French, the study aims to document more broadly the effects of the acoustic limitations of CI in processing segments characterized by acoustic cues that require optimal spectral resolution. The impact of various factors related to children's characteristics, such as chronological/auditory age, age of implantation, and exposure to cued speech, has been studied on performance, and the acoustic characteristics of the stimuli in perceptual tasks have also been investigated. METHOD: Identification and discrimination tasks involving French nasal and oral vowels were administered to two groups of children: 13 children with CIs (CI group) and 25 children with TH (TH group) divided into three age groups (4-6 years, 7-9 years, and 10-12 years). French nasal vowels were paired with their oral phonological counterpart (phonological pairing) as well as to the closest oral vowel in terms of phonetic proximity (phonetic pairing). Post hoc acoustic analyses of the stimuli were linked to the performance in perception. RESULTS: The results indicate an effect of the auditory status on the performance in the two tasks, with the CI group performing at a lower level than the TH group. However, the scores of the children in the CI group are well above chance level, exceeding 80%. The most common errors in identification were substitutions between nasal vowels and phonetically close oral vowels as well as confusions between the phoneme /u/ and other oral vowels. Phonetic pairs showed lower discrimination performance in the CI group with great variability in the results. Age effects were observed only in TH children for nasal vowel identification, whereas in children with CIs, a positive impact of cued speech practice and early implantation was found. Differential links between performance and acoustic characteristics were found within our groups, suggesting that in children with CIs, selective use of certain acoustic features, presumed to be better transmitted by the implant, leads to better perceptual performance. CONCLUSIONS: The study's results reveal specific challenges in children with CIs when processing segments characterized by fine spectral resolution cues. However, the CI children in our study appear to effectively compensate for these difficulties by utilizing various acoustic cues assumed to be well transmitted by the implant, such as cues related to the temporal resolution of stimuli.

Objectives: Our aim is to detect early, subclinical speech biomarkers of dysarthria in Parkinson's disease (PD), i.e., systematic atypicalities in speech that remain subtle, are not easily detectible by the clinician, so that the patient is labeled "non-dysarthric." Based on promising exploratory work, we examine here whether vowel articulation, as assessed by three acoustic metrics, can be used as early indicator of speech difficulties associated with Parkinson's disease. Study design: This is a prospective case-control study. Methods: Sixty-three individuals with PD and 35 without PD (healthy controls-HC) participated in this study. Out of 63 PD patients, 43 had been diagnosed with dysarthria (DPD) and 20 had not (NDPD). Sustained vowels were recorded for each speaker and formant frequencies were measured. The analyses focus on three acoustic metrics: individual vowel triangle areas (tVSA), vowel articulation index (VAI) and the Phi index. Results: tVSA were found to be significantly smaller for DPD speakers than for HC. The VAI showed significant differences between these two groups, indicating greater centralization and lower vowel contrasts in the DPD speakers with dysarhtria. In addition, DPD and NDPD speakers had lower Phi values, indicating a lower organization of their vowel system compared to the HC. Results also showed that the VAI index was the most efficient to distinguish between DPD and NDPD whereas the Phi index was the best acoustic metric to discriminate NDPD and HC. Conclusion: This acoustic study identified potential subclinical vowel-related speech biomarkers of dysarthria in speakers with Parkinson's disease who have not been diagnosed with dysarthria.
RESUMEN
To respond to the need of objective screening tools for motor speech disorders (MSD), we present the screening version of a speech assessment protocol (MonPaGe-2.0.s), which is based on semi-automated acoustic and perceptual measures on several speech dimensions in French. We validate the screening tool by testing its sensitivity and specificity and comparing its outcome with external standard assessment tools. The data from 80 patients diagnosed with different types of mild to moderate MSD and 62 healthy test controls were assessed against the normative data obtained on 404 neurotypical speakers, with Deviance Scores computed on seven speech dimensions (voice, speech rate, articulation, prosody, pneumophonatory control, diadochokinetic rate, intelligibility) based on acoustic and perceptual measures. A cut-off of the MonPaGe total deviance score (TotDevS) >2 allowed MSD to be diagnosed with specificity of 95% and an overall sensitivity of 83.8% on all patients pulled, reaching 91% when very mildly impaired patients were excluded. A strong correlation was found between the MonPaGe TotDevS and an external composite perceptual score of MSD provided by six experts. The MonPaGe screening protocol has proven its sensitivity and specificity for diagnosing presence and severity of MSD. Further implementations are needed to complement the characterization of impaired dimensions in order to distinguish subtypes of MSD.

OBJECTIVE: Acoustic parameters are widely used as voice quality therapeutic outcomes in many laryngological diseases. The aim of this study is to explore the impact of changes in the nature and duration of the analyzed time interval and the vowel choice on the significance of the acoustic measurements used as therapeutic outcomes in two different diseases. STUDY DESIGN: A prospective case series. MATERIAL AND METHODS: From September 2013 to January 2018, patients with laryngopharyngeal reflux (LPR) disease were recruited and treated with pantoprazole, diet, and behavioral changes for 3 months. The reflux symptom index and reflux finding score were used for both diagnosis and assessment of treatment effectiveness. Simultaneously, patients with early idiopathic Parkinson's disease (IPD) were enrolled and benefited from a levodopa challenge test. An Iowa Oral Performance Instrument was used for objective outcomes in the assessment of levodopa effectiveness on muscular strength of IPD patients. Acoustic measurements were performed in both groups pre- and postmedication intake at different time intervals, including the "most stable" time intervals of 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds and a 1 second-time interval positioned at mid-production. We also measured acoustic parameters on the entire signal of three vowels and on the signal of each vowel being taken separately. RESULTS: A total of 80 LPR and 19 IPD patients met our inclusion criteria and completed the study protocol. LPR and IPD patients had significant clinical improvements throughout treatment, according to reflux symptom index, reflux finding score, and Iowa Oral Performance Instrument scores. The acoustic analysis revealed that acoustic parameters significantly improved from pre- to post-treatment and varied across methods used for measurement. The duration and position of the analyzed time interval in the production and the vowel on which the acoustic measures were made yielded considerable differences in the results. CONCLUSION: Depending on the time interval over which the acoustic parameters are measured, the clinically demonstrated effect of the medication may or may not be statistically demonstrated irrespective of the disease. According to the results of this study and regarding the lack of standardization of acoustic measurement methods, a line of thought is proposed to bypass the interval selection problem.

OBJECTIVE: To assess the usefulness of orofacial strength and voice quality as assessment of response to levodopa challenge test (LCT) used in the diagnosis of early idiopathic Parkinson disease (IPD). STUDY DESIGN: Controlled Prospective Study. METHODS: From January 2014 to April 2019, patients with early IPD and healthy individuals were recruited and evaluated for clinical findings (Hoehn and Yahr scale; Unified Parkinson's Disease Rating Scale); Voice Handicap Index (VHI); grade of dysphonia, roughness, breathiness, asthenia, and strain and instability (GRBASI); maximal phonation time; phonation quotient; acoustic parameters; and orofacial muscle strength Oral Performance Instrument (IOPI; IOPI Medical, Woodinville, WA, USA) t) at baseline and 45 minutes after the levodopa intake (LCT). RESULTS: A total of 32 IPD patients and 20 healthy individuals completed the study. Healthy individuals exhibited better VHI, grade of dysphonia, breathiness, asthenia, strain, instability, and acoustic measurements (noise-related, tremor, F0 short- and mid-term and intensity short-term parameters) than healthy subjects. The mean values of muscle strength of lips, cheeks, fundamental frequency (F0), highest F0, and shimmer significantly improved from pre- to post-LCT in IPD patients. Healthy individuals did not exhibit significant changes of orofacial strength and voice quality assessment from pre- to post-LCT. Significant associations were found between clinical, orofacial strength, and some aerodynamic and acoustic measurements. CONCLUSION: Orofacial strength and acoustic voice quality measurements may be used as objective outcomes of the LCT responsiveness in patients with early IPD. LEVEL OF EVIDENCE: 3A.

PURPOSE: To study the usefulness of voice quality as therapeutic outcome in laryngopharyngeal reflux disease. MATERIAL AND METHODS: A total of 80 patients with reflux finding score (RFS) > 7 and reflux symptom index (RSI) > 13 were treated with pantoprazole, diet, and lifestyle recommendations for 3 months. The therapeutic effectiveness was assessed with RSI; RFS; Voice Handicap Index; blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability (GRBASI); aerodynamic and a panel of acoustic measurements before and after treatment. A correlation analysis between symptoms, videolaryngostroboscopic signs, and acoustic measurements was conducted. RESULTS: Compared to baseline, means of RSI, RFS, Voice Handicap Index, perceptual dysphonia, and roughness significantly decreased. Significant improvements of phonatory quotient, percent jitter, percent shimmer, Relative Average Perturbation, Pitch Perturbation Quotient, Phonatory F0 Range, Amplitude Perturbation Quotient, smooth Amplitude Perturbation Quotient, and Peak-to-Peak Amplitude Variation were found at the end of treatment. Studies of correlation did not identify relevant correlation between videolaryngostroboscopic signs, especially vocal folds edema, and objective voice quality evaluations. CONCLUSION: Voice quality assessments can help to better understand voice disorders and can be used as indicators of the treatment effectiveness in patients with laryngopharyngeal reflux-related symptoms.

The aim of the present study is to contribute to the description of the speech production deficits in French-speaking aphasic patients, so as to shed light on their potential phonetic and/or phonological disorders. Acoustic studies of aphasics' speech productions remain relatively infrequent, especially in French, and when entering into the specifics, often lead to inconsistent results. We conducted a multiple-case study on six aphasic patients, four with non-fluent aphasia and two with fluent aphasia. They were administered a variety of language and neuropsychological tasks, then they participated in a customized non-word repetition task. Acoustic analyses of their speech productions were performed, focussing on VOT as the main acoustic correlate of the voicing contrast for oral stops. Other atypicalities in their productions were also classified. Results showed variable and mainly "mixed" phonetic-phonological impairment profiles that differed from the traditional hypotheses made in the literature about the speech deficits to be expected as a function of type of aphasia. Our results support the use of acoustic analyses in order to complete language examination in aphasic patients but also suggest that the frontier between phonological and phonetic impairment is not clear-cut. These outcomes are better accounted for by theories and models postulating close relationships between the phonological and phonetic levels of processing.

PURPOSE: Several perceptual scales have been developed to assess voice quality in dysphonic voices, among which the Grade Roughness Breathiness Asthenia Strain and a Rate of Dysphonia scale is probably the most frequently used. However, this clinical tool has not been properly validated with a normophonic population yet. The aim of the present study was to provide a first set of reference data gathered from a normal population, to serve as a basis of comparison for vocologists and laryngologists working with French-speaking patients. A second goal was to investigate the influence on this normal voice dataset, of variables known to affect perceptual judgments of pathological voice. MATERIAL AND METHODS: Sustained vowels and sentences produced by 80 healthy, normophonic French native speakers were perceptually assessed by a panel of 18 raters (nine students, nine experts) using the Grade Roughness Breathiness Asthenia Strain and a Rate of Dysphonia scale. RESULTS: The average overall grade was close to 1 on the (0 to 3) scale, questioning the notion of "normal" voice as opposed to dysphonic voice. Rating reliability as well as perceptual scores were affected by task-, speaker-, and listener-related factors: speech stimuli led to better rating reliability and were judged less severely than voice stimuli; experts were slightly more reliable and less severe than students; older speakers were unanimously considered as more dysphonic. Multiple interactions between these factors were observed, confirming the multidimensional nature of voice quality.

Laryngopharyngeal reflux (LPR) is an inflammatory condition suspected to be associated with dysphonia. In this study, we investigated multidimensional perceptual, aerodynamic, and acoustic voice changes in patients with clinically diagnosed LPR compared to healthy participants. We prospectively included 80 outpatients with Reflux Finding Score (RFS) >7 and Reflux Symptom Index (RSI) >13 from September 2013 to April 2016 and we compared clinical and voice quality assessments of these patients with 80 healthy participants. Statistically significant differences were found between groups with regard to Voice Handicap Index, perceptual voice quality (grades of dysphonia, roughness, strain, breathiness, asthenia, and instability), phonatory quotient, percentage jitter, percentage shimmer, peak-to-peak amplitude variation, standard deviation of fundamental frequency, and noise to harmonic ratio. Granulation score of RFS was found to affect the highest number of acoustic parameters. We did not identify significant correlation between vocal fold edema and objective voice quality measurements. This study supports that patients with LPR have significant deterioration of both subjective and objective voice quality compared to healthy participants.

OBJECTIVE: To investigate the usefulness of voice quality assessment as a treatment outcome in responder and nonresponder patients with laryngopharyngeal reflux (LPR). MATERIAL AND METHODS: Eighty clinically diagnosed LPR patients with reflux finding score (RFS) > 7 and reflux symptom index (RSI) > 13 were treated with pantoprazole, lifestyle changes, and diet recommendations for three months. RSI; RFS; Voice Handicap Index; blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability; aerodynamic and acoustic measurements were assessed at baseline and after treatment. These data were analyzed and compared with regard to the clinical evolution of patients (responder versus nonresponder). Patients who significantly improved RSI ≤ 13 and RFS ≤ 7 after treatment were considered as responder. Nonresponders were defined as patients with RSI > 13 and/or RFS > 7 at the end of treatment. Studies of correlation between the adherence to the diet regimen and the evolution of both signs and symptoms and between videolaryngostroboscopic signs; blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability; and acoustic measurements were conducted. RESULTS: Significant improvements in RSI, RFS, Voice Handicap Index, perceptual voice quality (dysphonia and roughness), and some fundamental frequency and intensity perturbation cues (phonatory fundamental frequency range, percent jitter, pitch perturbation quotient, relative average perturbation, percent shimmer, smoothed amplitude perturbation quotient, amplitude perturbation quotient, and peak-to-peak amplitude variation) were mainly identified after treatment in responder patients. The clinical and voice quality improvements of nonresponder patients were lower; highlighting a similar evolution of symptoms, signs, and voice quality. The correlation analysis revealed significant relationships between the adherence to lifestyle changes and diet recommendations and the improvement of symptoms and substantial correlations between breathiness and fundamental frequency perturbation parameters. CONCLUSION: Voice quality assessments can be used as indicators of the treatment effectiveness in patients with LPR. Voice quality improvement seems to be consistently associated with clinical improvement.

OBJECTIVE: To study the differences in perceptual ratings of mild and moderate dysphonia related to the speech task, and their impact on intrarater and interrater reliabilities. PATIENTS AND METHODS: Voice recordings of 15 outpatients with mild or moderate dysphonia related to laryngopharyngeal reflux were presented to 6 female experienced judges blinded to the clinical state of the patients. From these, the GRBASI (Grade, Roughness, Breathiness, Asthenia, Strain, and Instability) evaluations were performed on connected speech and sustained vowel of the pretreatment voice recordings and absolute agreement, and both intrarater and interrater reliabilities were assessed. RESULTS: The average GRBASI scores were significantly worse when performed on sustained vowel. Intrarater reliability substantially varied according to the judge and the task. Good interrater reliability was broadly found for the evaluations of all GRBASI components irrespective of the speech task. Concerning agreement, we only found absolute agreement between judges for G and R items assessed on text. CONCLUSION: Average grade of perceptual voice impairment, intrarater reliability, and agreement vary according to the speech task.

OBJECTIVE: To investigate the voice quality impairments in patients with laryngopharyngeal reflux (LPR) according to the gender. DESIGN: Controlled multi-center study. MATERIALS AND METHODS: 80 LPR patients (40 males and 40 females) with reflux finding score (RFS) > 7 and reflux symptom index (RSI) > 13 were included and clinically compared according to gender. To be considered as LPR patients, subjects responded to an empiric therapeutic trial based on pantoprazole intake and diet recommendations for 3 months or had positive pH/Impedance metry. Voice Handicap Index (VHI); Short Form Healthy Survey 36 (SF36), blinded Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI); aerodynamic and acoustic measurements were assessed in all patients and compared with 80 healthy controls (40 males and 40 females) according to gender. RESULTS: The most common reasons for the consultation were, respectively, globus sensation in males (22.5%) and dysphonia (27.5%) in female who complained more of breathing difficulties and choking episodes related to LPR than males (p = 0.024). From a quality of life standpoint, female had increased significant impact of LPR disease on vitality and mental health than male. Compared to healthy subjects, both LPR male and female patients had stronger values of G, R, B, S, I, VHI, percent jitter, percent shimmer, and soft palate index than controls. In addition, LPR female had stronger values of lowest fundamental frequency and all aerodynamic measurements than controls. CONCLUSION: As showed in many other laryngeal conditions, voice quality of female could be more impaired by LPR than male. Some anatomical, histological and functional factors can be suspected and need additional future researches.

OBJECTIVES: The study aimed to investigate the impact of chemoradiotherapy (CRT) on speech and voice quality according to the anatomic localization of the head and neck cancer. METHODS: Thirty-four patients treated by CRT for advanced suprahyoid (N = 17) or infrahyoid (N = 17) cancer were assessed for speech function, videolaryngostroboscopy, Voice Handicap Index, blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability, acoustic measurements, and aerodynamic measurements. Quality of life was evaluated using the European Organization for Research and Treatment of Cancer Head and Neck 35 (EORTC QLQ-H&N35) questionnaire. RESULTS: Patients treated for an infrahyoid tumor presented more severe values of Voice Handicap Index items, dysphonia, breathiness, asthenia, and some acoustic cues (Voice Turbulence Index, Soft Phonation Index, degree of unvoiced segments, and number of unvoiced segments) than patients treated for a suprahyoid tumor. The EORTC QLQ-H&N35 communication item was better in the suprahyoid patient group. CONCLUSIONS: Voice quality impairments associated with CRT are more severe in patients treated for advanced infrahyoid cancer, suggesting the need to develop specific posttherapy management of the dysphonia according to the tumor anatomical localization.

The objective is to assess the differences in the severity of symptoms, signs, voice quality, and quality of life before and after treatment according to age in suspected laryngopharyngeal reflux (LPR) patients. The design used in this paper is prospective multi-center study. Eighty clinically diagnosed LPR patients with a reflux finding score (RFS) >7 and a reflux symptom index (RSI) >13 were treated with pantoprazole and diet recommendations for 3 months. Patients were subdivided into three groups according their age: group 1 (18-39 years, N = 21), group 2 (40-59 years, N = 31), and group 3 (≥60 years, N = 28). RSI, RFS, Voice Handicap Index (VHI), Short Form 36 questionnaire (SF36), aerodynamic, and acoustic measurements were evaluated at baseline and after treatment. The response to the empiric treatment was also assessed. Significant improvements in RSI, RFS, and VHI were found in all patient groups. The elderly patients showed a significantly lower RSI score than younger subjects (p = 0.035) without RFS difference among groups. At baseline, the SF36 score was better in group 3 with respect to social functioning (p = 0.049). At the 3-month follow-up, we found significant improvement of acoustic parameters only in the younger age groups (group 1 and group 2). The rate of resistant patients to the empiric treatment was higher in the younger group than in the elderly patient group (42.9 versus 28.6%). Age appears to reduce the subjective LPR symptom perception, leading to a lower rate of uncured patients. The utilization of acoustic parameters as an indicator of treatment effectiveness seems less useful for elderly subjects, probably due to an overlap between an aging voice and LPR.

OBJECTIVE: To develop a French version of the Reflux Symptom Index (Fr-RSI) and to assess its internal consistency, reliability, and clinical validity. STUDY DESIGN: Controlled, prospective trial. MATERIALS AND METHODS: Forty-four patients with a reflux finding score > 7 and an Fr-RSI > 13 were enrolled and treated with 20 mg of pantoprazole twice daily and diet changes for 3 months. Ninety asymptomatic subjects were also included in the study. To assess reliability, Fr-RSI was completed twice within a 7-day period. Validity was assessed by comparing Fr-RSI scores with scores from the Voice Handicap Index (VHI) in 24 of 44 patients, at baseline and at 3 months posttherapy. RESULTS: The mean values of Fr-RSI at baseline and after 7 days were 20.17 ± 5.76 and 19.75 ± 7.08, respectively, for patients with laryngopharyngeal reflux (LPR) and 4.02 ± 3.49 and 3.71 ± 3.82, respectively, for controls. The test-retest reliability was high in patients with LPR (rBP = 0.78) and in healthy subjects (rBP = 0.80). Cronbach's alpha was 0.85, indicating high internal consistency. The mean Fr-RSI score significantly improved from a baseline of 20.17 ± 5.76 to 5.58 ± 3.65 after 3 months of treatment (P = 0.001), and the initial mean VHI total score significantly improved from 20.29 ± 19.62 to 12.87 ± 12.04 after treatment (P = 0.029), indicating validity of the results. However, of the subcategories of the VHI, only the mean physical score improved from a baseline of 11.19 ± 9.22 to 7.35 ± 5.96 after treatment (P = 0.016). CONCLUSION: The Fr-RSI developed in this study demonstrated both reliability and validity. It can be easily administered to assist in diagnosing and monitoring of LPR in French-speaking patients.

The aim of this study is to explore voice quality modifications in laryngopharyngeal reflux (LPR) disease and to understand better the pathophysiological mechanisms underlying the development of communicative disability. Biological Abstracts, BioMed Central, Cochrane database, PubMed and Scopus were assessed for subject headings using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) recommendations. Relevant studies published between January 1990 and December 2015 describing the evaluation of voice quality in LPR disease were retrieved. Issues of clinical relevance, such as LPR diagnosis method, treatment efficacy and outcomes, were evaluated for each study. We determined the grade of recommendation for each publication according to the Oxford Centre for Evidence-Based Medicine evidence levels. The search identified 145 publications, of which 25 studies met the inclusion criteria for a total of 1483 LPR patients. Data were extracted by 2 independent physicians who identified 16 trials with a IIb evidence level, 7 trials with a IIa evidence level and 2 RCTs with a Ib evidence level where 4 patient-based instruments and 5 clinician-based instruments were used. The main voice assessment outcomes reported were hoarseness assessments by physicians or patients, followed by acoustic parameters; 15 and 14 articles, respectively, demonstrated significant improvements in subjective and objective voice assessments after treatment. The methodology used to measure acoustic parameters (i.e. sustained vowel duration, the sample portion choice for measurement, etc.) varied from one study to another. The majority of studies indicated that voice quality assessments (especially acoustic parameters) remain an interesting outcome to measure the effectiveness of treatment, but further studies using standardised and transparent methodology to measure acoustic parameters are necessary to confirm the place of each tool in the LPR disease evaluation.

OBJECTIVES: The study aimed to explore the impact of the selection of the analyzed time interval on the significance of acoustic measurements used to investigate laryngopharyngeal reflux (LPR) treatment efficacy, and based on these results to develop an alternative statistical approach in data analysis focusing on individual patient vocal behavior. STUDY DESIGN: This is a prospective case series. METHODS: From September 2013 to July 2015, 41 patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily and diet behavioral changes for 3 months. Voice recordings were performed at baseline and after 3 months of treatment. Most stable time intervals of 1, 2, 3, 4, and 5 seconds, and a 1-second time interval positioned at mid-production, were subjected to acoustic analysis. Based on the latter, we developed an "informativeness coefficient" for each acoustic parameter that aimed at assessing its sensitivity to clinical resolution in the case of LPR disease. RESULTS: Significant clinical improvement (RSI and RFS) was observed after treatment (P < 0.05). The acoustic analysis revealed that acoustic parameters significantly improving from pre- to posttreatment varied across time intervals. The duration and the position of the analyzed time interval in the production yielded considerable differences in the results. Analysis of the informativeness coefficient indicated that jitter, jitter percent, relative average perturbation (RAP), pitch perturbation quotient (PPQ), shimmer (ShdB), shimmer percent (Shim), amplitude perturbation quotient (APQ), and smoothed amplitude perturbation quotient (sAPQ) were the indices most sensitive to medical treatment efficacy, with a coefficient ranging from 75.86% to 86.21%. CONCLUSIONS: Depending on the selection of the time interval over which the acoustic parameters are measured, the potential effect of the treatment may or may not be statistically demonstrated. Future studies are needed to establish standardized methodological procedures for acoustic data analysis.

BACKGROUND: Laryngopharyngeal reflux is a prevalent, not well-understood disease affecting a high proportion of patients who seek laryngology consultation. The objective of this prospective case series is to explore the subjective and objective voice modifications in Laryngopharyngeal reflux (LPR), especially the usefulness of acoustic parameters as treatment outcomes, and to better understand the pathophysiological mechanisms underlying the development of voice disorder. METHODS: Forty-one patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily for three months. RSI, RFS, Voice Handicap Index (VHI), and Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI) were assessed at baseline and after three months post-therapy. Acoustic parameters were measured by selecting the most stable interval of the vowel /a/. A study of correlations between acoustic measurements and laryngoscopic signs was conducted in patients with roughness. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS). RESULTS: Significant improvement in RSI, RFS, VHI, jitter, percent jitter, relative average perturbation (RAP), shimmer, percent shimmer, and amplitude perturbation quotient (APQ) was found at 3 months of treatment (p < .05). A correlation analysis revealed significant correlations between the grade of dysphonia, breathiness, asthenia, instability and jitter, percent jitter, RAP, shimmer, percent shimmer and APQ. In dividing our cohort into two groups of patients according to the presence of roughness, shimmer, percent shimmer and APQ significantly improved in patients with roughness, but no positive correlation was found between acoustic parameters and laryngoscopic signs. CONCLUSION: Acoustic parameters can help to better understand voice disorders in LPR and can be used as treatment outcomes in patients with roughness.

In this paper, we introduce the concept of "phonetic compliance," which is defined as the intrinsic individual ability to produce speech sounds that are unusual in the native language, and constitutes a part of the ability to acquire L2 phonetics and phonology. We argue that phonetic compliance represents a systematic source of variance that needs to be accounted for if one wants to improve the control over the independent variables manipulated in SLA experimental studies. We then present the results of a two-fold proof-of-concept study aimed at testing the feasibility of assessing phonetic compliance in terms of gradient. In study 1, a pilot data collection paradigm is implemented on an occasional sample of 10 native French speakers engaged in two reproduction tasks involving respectively vowels and aspirated stops, and data are analyzed using descriptive statistics. In study 2, complementary data including L1-typical realizations are collected, resulting in the development of a first set of indicators that may be useful to appropriately assess, and further refine the concept of, phonetic compliance. Based on a critical analysis of the contributions and limitations of the proof-of-concept study, general discussion formulates the guidelines for the following stages of development of a reliable and valid test of phonetic compliance.
RESUMEN
This paper deals with the influence of ambient speech on individual speech productions. A methodological framework is defined to gather the experimental data necessary to feed computer models simulating self-organisation in phonological systems. Two experiments were carried out. Experiment 1 was run on French native speakers from two regiolects of Belgium: two from Liège and two from Brussels. When exposed to the way of speaking of the other regiolect via loudspeakers, the speakers of one regiolect produced vowels that were significantly different from their typical realisations, and significantly closer to the way of speaking specific of the other regiolect. Experiment 2 achieved a replication of the results for 8 Mons speakers hearing a Liège speaker. A significant part of the imitative effect remained up to 10 min after the end of the exposure to the other regiolect productions. As a whole, the results suggest that: (i) imitation occurs automatically and unintentionally, (ii) the modified realisations leave a memory trace, in which case the mechanism may be better defined as 'mimesis' than as 'imitation'. The potential effects of multiple imitative speech interactions on sound change are discussed in this paper, as well as the implications for a general theory of phonetic implementation and phonetic representation.
