Purpose: This study collected measures of auditory-perceptual and oral somatosensory acuity in typically developing children and adolescents aged 9-15 years. We aimed to establish reference data that can be used as a point of comparison for individuals with residual speech sound disorder (RSSD), especially for RSSD affecting American English…

Purpose: Nonnative consonant cluster learning has become a useful experimental approach for learning about speech motor learning, and we sought to enhance our understanding of this area and to establish best practices for this type of research. Method: One hundred twenty individuals completed a nonnative consonant cluster learning task within a…

Purpose: Generalizations can be made about the order in which speech sounds are added to a child's phonemic inventory and the ways that child speech deviates from adult targets in a given language. Developmental and disordered speech patterns are presumed to reflect differences in both phonological knowledge and skilled motor control, but the…

Children with dysarthria due to cerebral palsy (CP) present with decreased vowel space area and reduced word intelligibility. Although a robust relationship exists between vowel space and word intelligibility, little is known about the intelligibility of vowels in this population. This exploratory study investigated the intelligibility of American…

The purpose of this study was to determine whether or not decreased articulation of speech played a role in the ability of an individual with Down syndrome or Fragile X syndrome to signal noncomprehension and whether the two groups differed in their levels of articulation of speech and noncomprehension signaling ability. The research was conducted…

Purpose: This study explored relationships among perceptual, ultrasound, and acoustic measurements of children's correct and misarticulated /r/ sounds. Longitudinal data documenting changes across these parameters were collected from 2 children who acquired /r/ over a period of intervention and were compared with data from children with typical…

English-speaking preschoolers who knew letters but were nonreaders (M = 4 years 9 months; n = 60) were taught to segment consonant-vowel (CV), VC, and CVC words into phonemes either with letters and pictures of articulatory gestures (the LPA condition) or with letters only (the LO condition). A control group received no treatment. Both trained…

The purpose of this descriptive investigation was to explore perceptual judgments of speech naturalness, compared to judgments of articulation, language, disfluency, and speaking rate, in the speech of two youths who differed in cluttering severity. Two groups of listeners, 48 from New York and 48 from West Virginia, judged 93 speaking samples on…

THE INVESTIGATION STUDIED THE RELATIONSHIPS BETWEEN (1) AUDITORY PERCEPTUAL ABILITIES AND ARTICULATION DEVELOPMENT AND (2) INVESTIGATED QUALITATIVE AND QUANTITATIVE ASPECTS OF THESE ABILITIES AS SHOWN IN MENTALLY RETARDED AND NORMAL CHILDREN. THE STUDY INVOLVED MONTHLY TESTING OF ARTICULATION, PHONETIC DISCRIMINATION, AND PHONETIC SYNTHESIS…

This transcript of and guide to a two-cassette course designed to assist New Yorkers in erasure of their accents can be used for either individual or group study. Narrative and taped demonstrations of Standard American English that pinpoint typical phonological barriers and pronunciation difficulties are outlined. The author's own system of…

THIS STUDY OF THE ARTICULATORY AND INTELLIGIBILITY LEVEL OF A SOCIALLY DISADVANTAGED GROUP OF CHILDREN IN THE HEAD START PROGRAM INVOLVED 150 CHILDREN, 4 1/2 - 6 YEARS OF AGE, WITH EQUAL NUMBERS OF BOYS AND GIRLS. THIS GROUP WAS COMPOSED OF CHILDREN OF FAMILIES WITH SPANISH LANGUAGE BACKGROUND, OF CHILDREN OF NATIVE NEGRO FAMILIES, AND OF CHILDREN…
