Infant-directed speech (IDS) is phonetically distinct from adult-directed speech (ADS): It is typically considered to have special prosody--like higher pitch and slower speaking rates--as well as unique speech sound properties, for example, more breathy, hyperarticulated, and/or variable consonant and vowel articulation. These phonetic features…

Purpose: Spoken language is inherently multimodal and multidimensional in natural settings, but very little is known about how second language (L2) learners undertake multilayered speech signals with both phonetic and affective cues. This study investigated how late L2 learners undertake parallel processing of linguistic and affective information…

We longitudinally investigated the development of deictic and general accompanying gestures in one 5-year-old boy with autism spectrum condition (ASC) and intellectual disability. The investigation was performed during an intervention focusing on phonological segments. The purpose was to see whether gestures developed in conjunction with language.…

The areas of "mispronunciation detection" (or "accent detection" more specifically) within the speech recognition community are receiving increased attention now. Two application areas, namely language learning and speech recognition adaptation, are largely driving this research interest and are the focal points of this work.…

This study investigates the phonetic implementation of stress in American English compounds by measuring the interaction of stress cues with different intonation patterns. Participants in an experiment produced compounds and phrases such as "greenhouse" and "green house" in different prosodic positions and sentence types to elicit the contrast in…

Imitation in speech refers to the unintentional transfer of phonologically irrelevant acoustic-phonetic information of auditory input into speech motor output. Evidence for such imitation effects has been explained within the framework of episodic theories. However, it is largely unclear, which neural structures mediate speech imitation and how…

This thesis provides a comprehensive account of the intonational phonology of Lakota, an indigenous North American language of the Siouan family. Lakota is predominantly a verb final language, characterized by complex verbal morphology. The phonological description of Lakota intonation and prosody presented here is based on acoustic analysis of…

Prosodic information aids segmentation of the continuous speech signal and thereby facilitates auditory speech processing. Durational and pitch variations are prosodic cues especially necessary to convey prosodic boundaries, but alaryngeal speakers have inconsistent control over acoustic parameters such as F0 and duration, being as a result noisy…

Experiments were conducted to examine the influence of syntactic boundaries on the operation of a phonological rule in speech production. Results indicate that traditional metrics of boundary strength, as well as linguistic formulations of phonological rules, must be elaborated to recognize the special status of clause boundaries and deletion…

A pneumotachographic investigation of intervocalic /p/, /t/ and /k/ was undertaken to isolate physiological parameters responsible for coarticulatory air-flow phenomena. Airflow was most sensitive during the /k/ closure phase. The dynamics of the closure phase for each place of articulation and their implications for pneumotachography are…

A study of the utterances of young children, aged 7 to 22 months, is described. These utterances, varying in length from one to 17 syllables, contain only suprasegmental information because the verbal content was incomprehensible to hearers who were not acquainted with the child and the situation in which the utterances occured. In the corpus,…

Reviews research on prosody and segmental perception, segmentation and invariance, categorical perception of speech and nonspeech, feature detectors, scaling speech sounds to an auditory-articulatory space, acoustic-phonetic dependencies within the syllable, higher order (nonphonetic) factors in the comprehension of fluent speech, and cerebral…

An approach to a contrastive analysis of phonologies for pedagogic purposes is illustrated through the discussion of selected problems of interference which arise in the teaching of Russian pronunciation to native speakers of American English. The need for a recognition of a hierarchy of errors and the importance of the phonetic level of analysis…

This is one of a series of reports intended to make the results of research available and to serve as progress reports. The following abstracts are included: (1) "Learning the Phonetic Cues to the Voiced-Voiceless Distinction: Preliminary Study of Four American English Speaking Children," Mel Greenlee; (2) "Learning the Phonetic Cues to the…

The material in this book is the result of an investigation to determine how to teach English intonation effectively and to find the smallest number of patterns which could be used as a basis for initial drills in the language. The book presents a statement of the structure of the English intonation system in relation to the structural systems of…
