Subjective impressions of speech delivery in Autism Spectrum Disorder (ASD) as monotonic or over-precise are widespread but still lack robust acoustic evidence. This study provides a detailed acoustic characterization of the specificities of speech in individuals with ASD using an extensive sample of speech data, from the production of narratives…

Background: Metronome-paced speech results in the elimination, or substantial reduction, of stuttering moments. The cause of fluency during this fluency-inducing condition is unknown. Several investigations have reported changes in speech pattern characteristics from a control condition to a metronome-paced speech condition, but failure to control…

Purpose: The purpose of this study was to describe normative and validation data on the Intelligibility in Context Scale (ICS; McLeod, Harrison, & McCormack, 2012c) for English-speaking children. Method: The ICS is a 7-item, parent-report measure of children's speech intelligibility with a range of communicative partners. Data were collected…

In spontaneous speech, speakers sometimes replace a word they have just produced or started producing by another word. The present study reports that in these replacement repairs, low-frequency replaced words are more likely to be interrupted prior to completion than high-frequency words, providing support to the hypothesis that the production of…

Using English as a global communicating tool makes Taiwanese people have to speak in English in diverse international situations. However, consonants and vowels in English are not all effortless for them to articulate. This phonological reduction study explores concepts about phonological (articulating system) approximation. From Taiwanese folks'…

This study explored the relationship between articulator movement and prosody in children at different developmental ages. Jaw, lower lip, and upper lip kinematics were examined in 4-, 7-, and 11-year-old children as they produced the declarative and interrogative forms of utterances "Show Bob a bot" and "Show Pop a pot." Articulator movement…

Thirty children (aged 4-10) and 10 adults repeated 2 target syllables, which were analyzed acoustically to evaluate development of identification and discrimination in children for the vowel duration cue to final consonant voicing. Results showed that category boundary, category separation, response consistency, and perceptual consistency…

Investigation into age-related differences in production of fricative-vowel syllables with 10 adults and 30 children (ages 3, 5, and 7) found that age-related differences in vocal-tract geometry didn't explain age-related differences in vowel effects on fricative noise; children master intersyllabic gestural organization prior to intrasyllabic…

Research reports on the nature of speech, instrumentation for the investigation of speech, and practical applications of research are included in this status report for the April 1-June 30, 1980, period. The reports deal with the following topics: (1) the perceptual equivalent of two acoustic cues for a speech contrast is specific to phonetic…

This report is one in a regular series on the status and progress of speech research. The 11 manuscript topics are: towards a theoretical reassessment of the role of proprioception in the perception and control of human movement, interarticulator programing in stop production, the beginnings of speech, proofreading errors on the word "the," the…

One of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical research applications, this report consists of 14 papers. Topics covered in the papers are (1) skilled actions, (2) the control of fundamental frequency declination, (3) selective effects of masking on speech…

This book is designed for use by the preschool and kindergarten instructor as an outline for teaching the sound and name of each letter of the alphabet. It may also serve as a speech improvement program for those students who may enter school with one or more articulation errors. The program may be used in other grades as a supplement to classroom…

Thirteen manuscripts and extended reports on the nature of speech, instrumentation for its investigation, and practical applications of research are presented in this status report on speech research for the period of July-December 1979. The topics dealt with include speech perception, children's memory for sentences and word strings in relation…

This report is one of a regular series on the status and progress of speech research. The 16 manuscript topics are: the relative accessibility of semantic and deep structure syntactic concepts, some relationships between articulation and perception, reflex activation of laryngeal muscles by sudden induced subglottal pressure changes, dynamic…
