The impact of enhanced Milieu teaching with phonological emphasis (EMT + PE) on the speech and language outcomes for toddlers with cleft palate in Brazil and the United States of America.

PURPOSE: The purpose of this study was to compare the speech and language outcomes of children with cleft palate with or without cleft lip (CP+/-L) in the USA to children with CP+/-L in Brazil who underwent intervention with enhanced Milieu teaching with phonological emphasis (EMT + PE), as there are few cross-country intervention comparisons for children with CP+/-L. METHOD: This is a retrospective analysis of 29 participants from the USA and 24 participants from Brazil who were matched on age. The US participants were between the ages of 13-35 months (M = 23.76), spoke Standard American English in the home, and were recruited from East Tennessee State University and Vanderbilt University. The Brazilian participants were between the ages of 20-34 months (M = 25.04), spoke Brazilian Portuguese in the home, and were recruited from the Hospital de Reabilitação de Anomalias Craniofaciais-Universidade de São Paulo. All treatment participants received EMT + PE from trained speech-language pathologists in hospital-university clinics. RESULT: The treatment groups demonstrated greater gains than comparison groups in percent consonants correct, number of different words, and expressive/receptive vocabulary. There was no main effect nor interaction by country. CONCLUSION: The application of EMT + PE in a second culture and language is a viable early intervention option for participants with CP+/-L.

Enhanced milieu teaching with phonological emphasis: A pilot, telepractice study for parent training in early intervention.

PURPOSE: This pilot study evaluated enhanced milieu teaching with phonological emphasis (EMT + PE) parent training intervention delivered through telepractice and its impact on parent implementation, child speech outcomes, and child language outcomes. METHOD: A multiple baseline design across behaviours was used to assess response to parent training and child outcomes. The intervention was delivered to four parents and their young children with repaired cleft palate. Speech production, receptive language, and expressive language were assessed prior to intervention. EMT + PE strategies including matched turns, modelling and expansions, and prompting/speech recasting were taught to parents using the teach-model-coach-review model. Social validity questionnaires were administered pre- and post-intervention to assess parents' rating of competence and confidence for managing their child's early development. Reliability and procedural fidelity were conducted. RESULT: All parents increased their use of modelling and expansions, and prompting and speech recasting in response to training, as evidenced by large effect sizes. Children also responded positively to these strategies by increasing percentage of consonants correct (PCC) and target vocabulary, although PCC gains were less than observed in a prior hybrid telepractice and face-to-face intervention. Social validity measures indicated parents increased their confidence to provide intervention for their children. CONCLUSION: This pilot study indicated that effective parent training in EMT + PE strategies can be delivered through telepractice.

Precision Medicine as a New Frontier in Speech-Language Pathology: How Applying Insights From Behavior Genomics Can Improve Outcomes in Communication Disorders.

PURPOSE: Precision medicine is an emerging intervention paradigm that leverages knowledge of risk factors such as genotypes, lifestyle, and environment toward proactive and personalized interventions. Regarding genetic risk factors, examples of interventions informed by the field of medical genomics are pharmacological interventions tailored to an individual's genotype and anticipatory guidance for children whose hearing impairment is predicted to be progressive. Here, we show how principles of precision medicine and insights from behavior genomics have relevance for novel management strategies of behaviorally expressed disorders, especially disorders of spoken language. METHOD: This tutorial presents an overview of precision medicine, medical genomics, and behavior genomics; case examples of improved outcomes; and strategic goals toward enhancing clinical practice. RESULTS: Speech-language pathologists (SLPs) see individuals with various communication disorders due to genetic variants. Ways of using insights from behavior genomics and implementing principles of precision medicine include recognizing early signs of undiagnosed genetic disorders in an individual's communication patterns, making appropriate referrals to genetics professionals, and incorporating genetic findings into management plans. Patients benefit from a genetics diagnosis by gaining a deeper and more prognostic understanding of their condition, obtaining more precisely targeted interventions, and learning about their recurrence risks. CONCLUSIONS: SLPs can achieve improved outcomes by expanding their purview to include genetics. To drive this new interdisciplinary framework forward, goals should include systematic training in clinical genetics for SLPs, enhanced understanding of genotype-phenotype associations, leveraging insights from animal models, optimizing interprofessional team efforts, and developing novel proactive and personalized interventions.

Virtual Post-Intervention Speech and Language Assessment of Toddler and Preschool Participants in Babble Boot Camp.

PURPOSE: Babble Boot Camp (BBC) is a parent-implemented telepractice intervention for infants at risk for speech and language disorders. BBC uses a teach-model-coach-review approach, delivered through weekly 15-min virtual meetings with a speech-language pathologist. We discuss accommodations needed for successful virtual follow-up test administration and preliminary assessment outcomes for children with classic galactosemia (CG) and controls at age 2.5 years. METHOD: This clinical trial included 54 participants, 16 children with CG receiving BBC speech-language intervention from infancy, age 2 years, five children receiving sensorimotor intervention from infancy and changing to speech-language intervention at 15 months until 2 years of age, seven controls with CG, and 26 typically developing controls. The participants' language and articulation were assessed via telehealth at age 2.5 years. RESULTS: The Preschool Language Scale-Fifth Edition (PLS-5) was successfully administered with specific parent instruction and manipulatives assembled from the child's home. The GFTA-3 was successfully administered to all but three children who did not complete this assessment due to limited expressive vocabularies. Referrals for continued speech therapy based on PLS-5 and GFTA-3 scores were made for 16% of children who received BBC intervention from infancy as compared to 40% and 57% of children who began BBC at 15 months of age or did not receive BBC intervention, respectively. CONCLUSIONS: With extended time and accommodations from the standardized administration guidelines, virtual assessment of speech and language was possible. However, given the inherent challenges of testing very young children virtually, in-person assessment is recommended, when possible, for outcome measurements.

Speech Production Errors in Children With Cleft Palate With or Without Cleft Lip.

PURPOSE: The purpose of this study was to describe the frequency of speech production errors in children with cleft palate with or without cleft lip (CP±L) and explore characteristics related to speech production errors. METHOD: Fifty-six children with nonsyndromic CP±L between the ages of 4;0 and 7;11 (years;months) were included in this study. The children's audio-recorded production of a sentence repetition task was transcribed using narrow transcription and coded for speech error type. RESULTS: Children used, on average, 18 speech errors during the sentence repetition task that sampled 59 phoneme targets. On average, phonological errors were used most frequently, with nine errors per sample, followed by anterior oral speech errors at four errors per sample, and non-oral compensatory errors at three errors per sample. Individual-level characteristics including age and cleft type were related to frequency of phonological errors and anterior oral speech errors, respectively. One treatment-level characteristic, hypernasality, was related to use of non-oral compensatory errors and passive speech errors. CONCLUSIONS: This study identified the most frequent speech production errors as phonological errors, followed by anterior oral speech errors and non-oral compensatory errors. Individual-level and treatment-level characteristics were related to speech production errors. Future research should explore additional characteristics that may influence use of speech production errors. Clinically, this study adds information regarding speech error types that should be monitored throughout cleft care, including phonological errors that were most prevalent among this sample.

Consonant-Vowel Transition Models Based on Deep Learning for Objective Evaluation of Articulation.

Spectro-temporal dynamics of consonant-vowel (CV) transition regions are considered to provide robust cues related to articulation. In this work, we propose an objective measure of precise articulation, dubbed the objective articulation measure (OAM), by analyzing the CV transitions segmented around vowel onsets. The OAM is derived based on the posteriors of a convolutional neural network pre-trained to classify between different consonants using CV regions as input. We demonstrate that the OAM is correlated with perceptual measures in a variety of contexts including (a) adult dysarthric speech, (b) the speech of children with cleft lip/palate, and (c) a database of accented English speech from native Mandarin and Spanish speakers.

Feasibility of a Proactive Parent-Implemented Communication Intervention Delivered via Telepractice for Children With Classic Galactosemia.

PURPOSE: This study evaluated the feasibility of Babble Boot Camp (BBC) for use with infants with classic galactosemia (CG) starting at less than 6 months of age. BBC is a parent-implemented intervention delivered by speech-language pathologists (SLPs) entirely via telepractice with the potential to increase access to early preventative interventions. We evaluated BBC feasibility based on acceptability, implementation, and practicality. METHOD: We obtained data from 16 parents of infants with CG (mean age at enrollment = 3.38 months) involved in a large randomized clinical trial of BBC. BBC uses a teach-model-coach-review approach to provide parents with strategies to support their child's communication development. Families completed, on average, eighty-one 15-min sessions over a 20-month intervention period. We drew data from surveys completed by parents at the end of the intervention period, intervention logs maintained by the SLPs, and intervention fidelity checks completed by research assistants. RESULTS: Data drawn from parent surveys, intervention logs, and intervention fidelity checks revealed high parent acceptability, high rates of completion and compliance, and low costs in terms of parent and clinician time. CONCLUSION: Results suggest that BBC is feasible for families of infants with CG, warranting further examination of BBC across a broader range of children with CG as well as other infants who are at predictable risk for speech and language impairment.

Translating principles of precision medicine into speech-language pathology: Clinical trial of a proactive speech and language intervention for infants with classic galactosemia.

Precision medicine is an emerging approach to managing disease by taking into consideration an individual's genetic and environmental profile toward two avenues to improved outcomes: prevention and personalized treatments. This framework is largely geared to conditions conventionally falling into the field of medical genetics. Here, we show that the same avenues to improving outcomes can be applied to conditions in the field of behavior genomics, specifically disorders of spoken language. Babble Boot Camp (BBC) is the first comprehensive and personalized program designed to proactively mitigate speech and language disorders in infants at predictable risk by fostering precursor and early communication skills via parent training. The intervention begins at child age 2 to 5 months and ends at age 24 months, with follow-up testing at 30, 42, and 54 months. To date, 44 children with a newborn diagnosis of classic galactosemia (CG) have participated in the clinical trial of BBC. CG is an inborn error of metabolism of genetic etiology that predisposes up to 85% of children to severe speech and language disorders. Of 13 children with CG who completed the intervention and all or part of the follow-up testing, only one had disordered speech and none had disordered language skills. For the treated children who completed more than one assessment, typical speech and language skills were maintained over time. This shows that knowledge of genetic risk at birth can be leveraged toward proactive and personalized management of a disorder that manifests behaviorally.

Early speech and language intervention in Brazilian-Portuguese toddlers with cleft lip and/or palate.

Young children with cleft palate with or without cleft lip (CL/P) are at risk for early vocabulary and speech sound production delays. Early intervention studies have shown some promising findings to promote early speech and vocabulary development following palate repair; however, we know little about how these interventions can be used in other international contexts. This study adapted an early speech and language intervention developed in the US, Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE), to the Brazilian context at the Hospital for Rehabilitation of Craniofacial Anomalies at the University of São Paulo-Bauru. The purpose of this study was to compare the speech and language performance of 24 toddlers with CL/P randomized into an EMT+PE intervention group and a business-as-usual (BAU) comparison group over three time points: prior to, immediately following, and three months after intervention. Results immediately following intervention indicate gains in multiple measures of language. Three months following intervention, participants showed gains in both language and speech measures.

Reading Development in Children With Nonsyndromic Cleft Palate With or Without Cleft Lip: Meta-analysis and Systematic Review.

OBJECTIVE: We conducted a meta-analysis and systematic review of literature comparing pre-reading and general reading in school-age children with nonsyndromic cleft palate with or without cleft lip (NSCP/L) to their peers without NSCP/L. METHODS: Our literature search identified 1238 possible records. After screening we identified 11 samples for inclusion for systematic review and eight for meta-analysis. We compared 292 children with NSCP/L to 311 peers for 23 pre-reading effect sizes and 17 general reading effect sizes (EFg). We conducted a random-effects metaregression using robust variance estimation. RESULTS: On average school-age children with NSCP/L scored lower on pre-reading (EFg = -0.36) and general reading measures (EFg = -0.38) compared to their peers. We conducted post-hoc analyses on phonological awareness and word decoding effect sizes; children with NSCP/L performed lower on phonological awareness (EFg = -0.22) and word decoding (EFg = -0.39) compared to their peers. There was weak evidence that hearing status and/or speech-language functioning might moderate reading development. There was limited evidence that age or socioeconomic status moderated reading development. However, samples did not consistently report several characteristics that were coded for this project. CONCLUSIONS: Our findings suggest that school-age children with NSCP/L have persistent reading problems. Further research is needed to explore reading development in children with NSCP/L, as well as the relationships among hearing, speech, language, and reading development.

Waveform Amplitude and Temporal Symmetric/Asymmetric Characteristics of Phoneme and Syllable Segments in the W-1 Spondaic Words Recorded by Four Speakers.

BACKGROUND: The amplitude and temporal asymmetry of the speech waveform are mostly associated with voiced speech utterances and are obvious in recent graphic depictions in the literature. The asymmetries are attributed to the presence and interactions of the major formants characteristic of voicing with possible contributions from the unidirectional air flow that accompanies speaking. PURPOSE: This study investigated the amplitude symmetry/asymmetry characteristics (polarity) of speech waveforms that to our knowledge have not been quantified. STUDY SAMPLE: Thirty-six spondaic words spoken by two male speakers and two female speakers were selected because they were multisyllabic words providing a reasonable sampling of speech sounds and four recordings were available that were not related to the topic under study. RESEARCH DESIGN: Collectively, the words were segmented into phonemes (vowels [130], diphthongs [77], voiced consonants [258], voiceless consonants [219]), syllables (82), and blends (6). For each segment the following were analyzed separately for the positive and negative datum points: peak amplitude, the percent of the total segment datum points, the root-mean-square (rms) amplitude, and the crest factor. DATA COLLECTION AND ANALYSES: The digitized words (44,100 samples/s; 16-bit) were parsed into 144 files (36 words × 4 speakers), edited, transcribed to numeric values (±1), and stored in a spread sheet in which all analyses were performed with in-house routines. Overall approximately 85% of each waveform was analyzed, which excluded portions of silent intervals, transitions, and diminished waveform endings. RESULTS: The vowel, diphthong, and syllable segments had durations (180-220 ms) that were about twice as long as the consonant durations (∼90 ms) and peak and rms amplitudes that were 6 to 12 dB higher than the consonant peak and rms amplitudes. Vowel, diphthong, and syllable segments had 10% more positive datum points (55%) than negative points (45%), which suggested temporal asymmetries within the segments. With voiced consonants, the distribution of positive and negative datum points dropped to 52 and 48% and essentially was equal with the voiceless consonants (50.3 and 49.6%). The mean rms amplitudes of the negative datum points were higher than the rms amplitudes for the positive points by 2 dB (vowels, diphthongs, and syllables), 1 dB (voiced consonants), and 0.1 dB (voiceless consonants). The 144 waveforms and segmentations are illustrated in the Supplementary Material along with the tabularized positive and negative segment characteristics. CONCLUSIONS: The temporal and amplitude waveform asymmetries were by far most notable in segments that had a voicing component, which included the voiced consonants. These asymmetries were characterized by larger envelopes and more energy in the negative side of the waveform segment than in the positive side. Interestingly, these segments had more positive datum points than negative points, which indicated temporal asymmetry. All aspects of the voiceless consonants were equally divided between the positive and negative domains. There were female/male differences but with these limited samples such differences should not be generalized beyond the speakers in this study. The influence of the temporal and amplitude asymmetries on monaural word-recognition performance is thought to be negligible.

Toward Preventing Speech and Language Disorders of Known Genetic Origin: First Post-Intervention Results of Babble Boot Camp in Children With Classic Galactosemia.

Purpose Babble Boot Camp (BBC) is a package of proactive activities and routines designed to prevent speech and language disorders in infants at predictable risk. It is implemented via parent training and currently undergoing clinical trial in children with a newborn diagnosis of classic galactosemia (CG), a metabolic disease with high risk of speech and language disorders. The purpose of this study is to provide updates to a previous pilot study and to present the first set of post-intervention results. Method The intervention and data collection occurred during child ages < 6-24 months, with follow-up assessments of speech and language at ages 2.5 and 3.5 years. Treatment targets included earliest vocalization rates, babble complexity, speech production accuracy, and vocabulary and syntactic growth. The oldest 15 children with CG (including three untreated controls) completed the first set of follow-up assessments. Aggregate data up to 10 months were available for 17 treated children with CG, six untreated children with CG, and six typical controls. Results At ages 7-9 months, babbling complexity, as measured with mean babbling level, was higher in the treated children with CG than in the untreated children with CG and the typical controls. Prior to 24 months of age, the treated children with CG had greater expressive but not receptive vocabulary sizes than an untreated control. Follow-up testing showed typical language scores for all 12 treated children with CG and typical articulation scores for 11 of these, whereas one of three untreated children with CG had low articulation and expressive language scores. Conclusions The BBC appears to be a viable intervention to support the speech and expressive language development of children with GC. Future studies will evaluate the relative contributions of the earliest and later BBC components to outcomes.

Enhanced Milieu Teaching with Phonological Emphasis: A Pilot Telepractice Parent Training Study for Toddlers with Clefts.

OBJECTIVE: the purpose of this study was to evaluate the effects of training caregivers to use intervention strategies from the Enhanced Milieu Teaching with Phonological Emphasis (EMT + PE) program, delivered via telepractice, and to examine the effects on child speech and language outcomes for children with repaired cleft lip +/- palate (CL/P). DESIGN: A multiple baseline within subject design across parent behaviors was replicated across three participating dyads. A pre-post intervention comparison was provided with a non-cleft twin. PARTICIPANTS: Three mother-child dyads participated in this study. Children ranged in age from 21 to 27 months at the beginning of the study and all had a diagnosis of CL/P. A noncleft twin without CL/P was assessed pre- and post-intervention to provide a normative comparison. RESULTS: Parents demonstrated a positive intervention effect by substantially increasing their use of EMT + PE intervention strategies during telepractice intervention sessions (Tau 0.675 to 1.1333). Following the conclusion of intervention, parents were able to maintain their use of strategies once direct coaching had been discontinued. Children demonstrated increased talking rate, improved speech production and expanded expressive vocabulary measures over the course of intervention. Speech and language development of a child without cleft palate was provided as a comparison. CONCLUSIONS: Parents were trained through telepractice to effectively deliver EMT + PE speech and language facilitation strategies that resulted in increased language and speech outcomes for their children with CL/P.

A phenotypically diverse family with an atypical 22q11.2 deletion due to an unbalanced 18q23;22q11.2 translocation.

The 22q11.2 deletion syndrome (22q11.2 DS) is the most common deletion syndrome in humans. In most cases, it occurs de novo. A rare family of three with 22q11.2 deletion syndrome (22q11.2 DS) resulting from an unbalanced 18q;22q translocation is reported here. Their deletion region is atypical in that it includes only 26 of the 36 genes in the minimal critical 22q11.2 DS region but it involves the loss of the centromeric 22q region and the entire p arm. The deletion region overlaps with seven other rare atypical cases; common to all cases was the loss of a region including SEPT5-GP1BB proximally and most of ARVCF distally. Interrogation of the deleted 22q region proximal to the canonical 22q11.2 deletion region in the DECIPHER database showed seven cases with isolated or combined traits of 22q11.2 DS, including three with clefts. The phenotypes in the present family thus may result from the loss of a subset of genes in the critical region, or alternatively the loss of other genes or sequences in the proximal 22q deletion region, or interactive effects among these. Despite the identical deletion locus in the three affected family members, expression of the 22q11.2 DS traits differed substantially among them. These three related cases thus contribute to knowledge of 22q11.2 DS in that their unusual deletion locus co-occurred with the cardinal features of the syndrome while their identical deletions are associated with variable phenotypic expression.

A Deep Learning Algorithm for Objective Assessment of Hypernasality in Children With Cleft Palate.

OBJECTIVES: Evaluation of hypernasality requires extensive perceptual training by clinicians and extending this training on a large scale internationally is untenable; this compounds the health disparities that already exist among children with cleft. In this work, we present the objective hypernasality measure (OHM), a speech-based algorithm that automatically measures hypernasality in speech, and validate it relative to a group of trained clinicians. METHODS: We trained a deep neural network (DNN) on approximately 100 hours of a publicly-available healthy speech corpus to detect the presence of nasal acoustic cues generated through the production of nasal consonants and nasalized phonemes in speech. Importantly, this model does not require any clinical data for training. The posterior probabilities of the deep learning model were aggregated at the sentence and speaker-levels to compute the OHM. RESULTS: The results showed that the OHM was significantly correlated with perceptual hypernasality ratings from the Americleft database (r = 0.797, p < 0.001) and the New Mexico Cleft Palate Center (NMCPC) database (r = 0.713, p < 0.001). In addition, we evaluated the relationship between the OHM and articulation errors; the sensitivity of the OHM in detecting the presence of very mild hypernasality; and established the internal reliability of the metric. Further, the performance of the OHM was compared with a DNN regression algorithm directly trained on the hypernasal speech samples. SIGNIFICANCE: The results indicate that the OHM is able to measure the severity of hypernasality on par with Americleft-trained clinicians on thisdataset.

Effects of a naturalistic intervention on the speech outcomes of young children with cleft palate.

Purpose: The purpose of this study was to investigate the extent to which a naturalistic communication intervention, Enhanced Milieu Teaching with Phonological Emphasis (EMT + PE) improved the speech outcomes of toddlers with cleft palate with or without cleft lip (CP ± L)Method: This study was a stratified randomised controlled trial.Setting: Treatment was delivered in a university clinic by a trained speech-language pathologist.Thirty children aged between 15 and 36 months (M = 25) with nonsyndromic CP ± CL and typical cognitive development were randomly assigned to a treatment (EMT + PE) or business as usual comparison condition.Participants in the EMT + PE treatment group received 48, 30-min sessions, over a 6-month period. Fidelity of treatment was high across participants.The primary outcome measures were percent consonants correct (PCC), consonant inventory, compensatory articulation errors, and nasal emission.Result: Regression analyses controlling for pre-intervention child characteristics were conducted for PCC and consonant inventory. Intervention was not a significant predictor of post-intervention outcome. Words per minute differentiated the children who benefitted from the intervention from those who did not. Reduction in compensatory errors and nasal emission occurred in both groups but to a greater degree in the EMT + PE group.Conclusion: EMT + PE is a promising early speech intervention for young children with CP ± L, especially for children with higher rates of word use.

Early Speech and Language Development in Children With Nonsyndromic Cleft Lip and/or Palate: A Meta-Analysis.

Objective The aim of the study was to conduct a meta-analysis of research examining the early speech and language functioning of young children, birth to age 8;11 (years;months), with nonsyndromic cleft lip and/or palate (NSCL/P) compared to their peers without NSCL/P. Method We conducted a random-effects metaregression using 241 effect sizes from 31 studies comparing 955 young children with NSCL/P to 938 typically developing peers on measures of speech and language functioning. Moderators were sample characteristics (i.e., age, cleft type, publication year, and study location) and measurement characteristics (i.e., speech sample material, language modality and domain, and assessment type). Results Young children with NSCL/P scored significantly lower on measures of speech and language compared to children without NSCL/P. Children with NSCL/P had smaller consonant inventories (standardized mean difference effect size [ESg] = -1.24), less accurate articulation (ESg = -1.13), and more speech errors (ESg = 0.93) than their peers. Additionally, children with NSCL/P had poorer expressive (ESg = -0.57) and receptive (ESg = -0.59) language skills than their peers. Age and assessment type moderated effect sizes for expressive language. As children with NSCL/P aged, their expressive language performance became more similar to their peers. Expressive language effect sizes from parent reports and observational language measures (estimated effect size = -0.74) were significantly lower than those from standardized norm-referenced tests (estimated effect size = -0.45). Conclusions These findings suggest that young children with NSCL/P experience delays relative to their peers across multiple speech and language constructs. Differences between children with NSCL/P and their typically developing peers appear to decrease with age. Supplemental Material https://doi.org/10.23641/asha.11356904.

The Influences of Child Intelligibility and Rate on Caregiver Responses to Toddlers With and Without Cleft Palate.

OBJECTIVE: The purpose of this study was to investigate the influences of child speech intelligibility and rate on caregivers' linguistic responses. DESIGN: This study compared the language use of children with cleft palate with or without cleft lip (CP±L) and their caregivers' responses. Descriptive analyses of children's language and caregivers' responses and a multilevel analysis of caregiver responsivity were conducted to determine whether there were differences in children's productive language and caregivers' responses to different types of child utterances. SETTING: Play-based caregiver-child interactions were video recorded in a clinic setting. PARTICIPANTS: Thirty-eight children (19 toddlers with nonsyndromic repaired CP±L and 19 toddlers with typical language development) between 17 and 37 months old and their primary caregivers participated. MAIN OUTCOME MEASURES: Child and caregiver measures were obtained from transcribed and coded video recordings and included the rate, total number of words, and number of different words spoken by children and their caregivers, intelligibility of child utterances, and form of caregiver responses. RESULTS: Findings from this study suggest caregivers are highly responsive to toddlers' communication attempts, regardless of the intelligibility of those utterances. However, opportunities to respond were fewer for children with CP±L. Significant differences were observed in children's intelligibility and productive language and in caregivers' use of questions in response to unintelligible utterances of children with and without CP±L. CONCLUSIONS: This study provides information about differences in children with CP±L's language use and caregivers' responses to spoken language of toddlers with and without CP±L.

Longitudinal Comparison of the Speech and Language Performance of United States-Born and Internationally Adopted Toddlers with Cleft Lip and Palate: A Pilot Study.

OBJECTIVE: This study compares the early speech and language development of children with cleft palate with or without cleft lip who were adopted internationally with children born in the United States. DESIGN: Prospective longitudinal description of early speech and language development between 18 and 36 months of age. PARTICIPANTS: This study compares four children (age range = 19 to 38 months) with cleft palate with or without cleft lip who were adopted internationally with four children (age range = 19 to 38 months) with cleft palate with or without cleft lip who were born in the United States, matched for age, gender, and cleft type across three time points over 10 to 12 months. MAIN OUTCOME MEASURES: Children's speech-language skills were analyzed using standardized tests, parent surveys, language samples, and single-word phonological assessments to determine differences between the groups. RESULTS: The mean scores for the children in the internationally adopted group were lower than the group born in the United States at all three time points for expressive language and speech sound production measures. Examination of matched pairs demonstrated observable differences for two of the four pairs. No differences were observed in cognitive performance and receptive language measures. CONCLUSIONS: The results suggest a cumulative effect of later palate repair and/or a variety of health and environmental factors associated with their early circumstances that persist to age 3 years. Early intervention to address the trajectory of speech and language is warranted. Given the findings from this small pilot study, a larger study of the long-term speech and language development of children who are internationally adopted and have cleft palate with or without cleft lip is recommended.

The Effects of Enhanced Milieu Teaching With Phonological Emphasis on the Speech and Language Skills of Young Children With Cleft Palate: A Pilot Study.

PURPOSE: The purpose of this pilot study was to investigate the extent to which a naturalistic communication intervention, enhanced milieu teaching with phonological emphasis (EMT+ PE), improved the language and speech outcomes of toddlers with cleft lip and/or palate (CL/P). METHOD: Nineteen children between 15 and 36 months (M = 25 months) with nonsyndromic CL/P and typical cognitive development were randomly assigned to a treatment (EMT+PE) or nontreatment, business-as-usual (BAU), experimental condition. Participants in the treatment group received forty-eight 30-min sessions, biweekly during a 6-month period. Treatment was delivered in a university clinic by trained speech language pathologists; fidelity of treatment was high across participants. RESULTS: Children in the treatment group had significantly better receptive language scores and a larger percentage of consonants correct than children in the BAU group at the end of intervention. Children in the treatment group made greater gains than children in the BAU group on most language measures; however, only receptive language, expressive vocabulary (per parent report), and consonants correct were significant. CONCLUSIONS: The results of this preliminary study indicate that EMT+PE is a promising early intervention for young children with CL/P. Replication with a larger sample and long-term follow-up measures are needed.
