Frequency Feature

This study examined the interaction of ambient frequency and feature complexity in the diphthong errors produced by Cantonese-speaking children with phonological disorders. A total of 611 diphthongs produced by 13 Cantonese-speaking children with speech disorders were subjected to perceptual analysis. The percentage accuracy of production and error patterns was examined. Perceptual analysis showed that /i/ and /ui/ were most frequently in error, whereas /ei/, /ou/, and /u/ were least frequently in error. Diphthong errors (usually diphthong reduction) arise as a function of both ambient frequency and feature complexity. The combination of ambient frequency and feature complexity yields a complexity metric reflecting accuracy of production. Treatment guidelines include consideration of three basic factors: ambient frequency, feature complexity, and error patterns.

This paper presents a case study of a Jordanian child with phonological speech disorders. It seeks to investigate functional phonological disorders and their treatment among Jordanian children within an Optimality Theoretic (OT) perspective. It aims to provide treatment for children’s speech errors within a constraint-based system. The analysis of the data identifies seven error patterns in the child’s productions, namely: fronting, lateralization, stopping, devoicing, de-emphasization, syllable deletion and cluster reduction. Furthermore, OT is employed at the end of the study as a guideline to select the priority of treatment goals by demoting responsible markedness constraints below faithfulness constraints.

Abstract Purpose Investigate the association between levodopa therapy and vocal characteristics in Parkinson’s disease patients. Search strategy Studies published at MEDLINE, LILACS, and SciELO, from 1960 to December 2016. A systematic review and meta-analysis was performed using the following keywords: Parkinson’s disease; levodopa; L-dopa; voice; speech disorders; dysphonia; dysarthria. After analyzing titles and abstracts, two independent reviewers selected all clinical trials that met the eligibility criteria and selected the articles and the data recorded in a previously standardized table. Selection criteria Trials published in English between 1960 and December 2016 individuals with clinical diagnosis of Parkinson’s disease; use of levodopa therapy in stable doses; acoustic analysis combined or not with auditory-perceptual analysis to evaluate the vocal parameters under investigation. Data analysis The following vocal parameters were analyzed: fundamental frequency (F 0), jitter, and vocal intensity. Standardized mean differences (SMD) were calculated using the Comprehensive Meta-analysis V2 software. Results Nine articles met the eligibility criteria and were selected, with a total of 119 individuals. From these, six articles with 83 individuals were included in the meta-analysis. During the levodopa therapy “on” state, modifications in F 0 (SMD=0.39; 95% CI - 0.21-0.57) and jitter (SMD=0.23; 95% CI - 0.02-0.45) were observed. Vocal intensity was not affected (SMD=0.09; 95% CI - 0.22-0.39) by levodopa ingestion. Data of the included studies were controversial in the auditory-perceptual analysis of voice. Conclusion Levodopa therapy modifies F0 and jitter. No changes in vocal intensity were observed in either the “on” or “off” states of levodopa therapy.

Fifteen caregivers each glossed a simultaneously videotaped and audiotaped sample of their child with speech delay engaged in conversation with a clinician. One of the authors generated a reference gloss for each sample, aided by (a) prior knowledge of the child’s speech-language status and error patterns, (b) glosses from the child’s clinician and the child’s caregiver, (c) unlimited replays of the taped sample, and (d) the information gained from completing a narrow phonetic transcription of the sample. Caregivers glossed an average of 78 of the utterances and 81 of the words. A comparison of their glosses to the reference glosses suggested that they accurately understood an average of 58 of the utterances and 73 of the words. Discussion considers the implications of such findings for methodological and theoretical issues underlying children’s moment-to-moment intelligibility breakdowns during speech-language processing.

Mode A

The pedigrees of 4 children with a severe phonological disorder demonstrating three generations of members with speech/language problems are presented. All 4 probands were female with two mothers, two fathers, and five out of six siblings affected. All pedigrees contained family members with dyslexia and learning disabilities as well as speech disorders. Family members varied in the type of speech problems that they demonstrated and the severity of their disorder, thus suggesting variable expressivity and incomplete penetrance. An autosomal dominant mode, a multifactorial-polygenic model, and a sex-specific threshold model for expression are discussed.

Subgroup Classification

Speech sound disorders affect more children than any other developmental communication disorder and are associated with long-term social and academic difficulties. The diversity of presenting symptoms has resulted in the need for classifying subgroups of speech disorders. Research on English-speaking children suggests that there are four types of surface speech error patterns (B. Dodd, 1995): articulation disorder (e.g., lisp); delay (i.e., normal developmental patterns that are inappropriate for chronological age); consistent use of atypical error patterns (e.g., deletion of all initial consonants); and inconsistent pronunciation of the same lexical items. Classification typologies should be language independent. This study investigated whether the same four subgroups, in similar proportions, would be found in German-speaking children who had disordered speech. A total of 110 monolingual German-speaking children, aged 2 years 7 months to 7 years 7 months, participated in the study. They had been referred for assessment of a suspected speech disorder. The results supported the subgroup classification, providing evidence for the universal character of speech disorders. One significant difference was the relatively high proportion of children classified as having an articulation disorder. This was explained by the uncertainty regarding a lisp as a disorder in German, since it is also found in up to 40% of normally developing children of the same age. The theoretical and clinical implications of the findings are discussed.

This tutorial presents an introduction to the contemporary linguistic framework known as optimality theory (OT). The basic assumptions of this constraint-based theory as a general model of grammar are first outlined, with formal notation being defined and illustrated. Concepts unique to the theory, including “emergence of the unmarked,” are also described. OT is then examined more specifically within the context of phonological acquisition. The theory is applied in descriptions of children's common error patterns, observed inter- and intrachild variation, and productive change over time. The particular error patterns of fronting, stopping, final-consonant deletion, and cluster simplification are considered from an OT perspective. The discussion concludes with potential clinical applications and extensions of the theory to the diagnosis and treatment of children with functional phonological disorders.

Children With Intellectual Disability

Phonology refers to the speech sound systems of a language. The term ‘phonemic’ refers to speech sound use. Most of the previous research reveals that phonological skills develop with age and thus older children had more accurate speech and fewer error patterns in their speech. The present study aimed to obtain extensive phonological data among in Hindi-speaking typically developing children across age-matched children with intellectual disability. The results revealed that phonology develops significantly with the age. Thus, older children had more accurate production and fewer error patterns in their speech relative to younger group. Also, typically developing children had a better control over their phonological aspects compared to children with intellectual disability.  A comparison with related studies has been discussed clearly in the paper which reveals a number of studies supporting the finding. The present study has significant implications for assessment of developmental speech disorders among Hindi-speaking Indian population.
