This paper proposes a set of underlying vowels, alternate to those of Chomsky and Halle, to account for vowel alternations. This phonetic representational system, which is to a degree an extension of Chomsky's and Halle's basic framework, is demonstrated in the Laxing Rule and the Vowel Alternation Rule for all vowel variables. An appendix…

The concept of the chorophone forms the basis for this study of vowel differences between Southern Negro English and Southern white English. The author isolates chorophones for the speech community under study according to the occurrence of a particular segmental phoneme or corresponding phoneme sequences in a set of words, all of which contain…

This book presents an acoustical and physiological Investigation of contemporary standard Arabic as spoken in Iraq. Spectrograms and X-ray sound films are used to perform the analysis for the study. With this equipment, the author considers the vowels, consonants, pharyngealized consonants, pharyngeals and glottals, duration, gemination, and…

This work contains five papers in the area of experimental linguistics. Papers include: (1) "Units of Speech Perception," a study which deals with problems of the temporal organization of speech; (2) a study, "Manner of Articulation, Parallel Processing, and the Perception of Duration," which examines the durational patterns characterizing the…

This project began with a theory about the prediction of errors in childrens' attempts to pronounce utterances modeled for them by adults. Subjects were children from 15 to 54 months old in all positions in the family. The sample from each child was an unprompted utterance judged to be an attempt to say something in English. Differences between…

Stampe's (1969, 1973) hypotheses regarding innate mental phonological processes are tested against some of the extant data on speech perception. (AM)

Presents two analyses of deviant phonological systems. The one based on production evidence alone accounts for (1) differences in surface behavior of a set of phonetic segments with three possible phoneme sources, and (2) obstruent clusters across morpheme boundaries. The "substitution analysis" identifies the child's underlying representations…

Compares the production of speech and sign: the approaches used in research, the cognitive processes involved, and the output timing mechanism. (AM)

This article describes the Colorado Phonetic/Phonologic Assessment of Hearing-Impaired Infants and Toddlers (PHONE) and the speech of 91 hearing-impaired infants and toddlers, examining number of vowels, consonants, elements per utterance, and utterances; differences by age and by hearing loss for each vowel and consonant; and relationship to…

This study evaluated the use of the computer-assisted accent-modification program, Speech Works, with beginning college students of English as a second language with a non-speech-language pathologist trainer. Students who had weekly one-on-one sessions with a teacher and independent practice, especially when the practice was computer monitored,…

This study investigated the encoding of syllable boundary information during speech production in Dutch. Based on Levelt's model of phonological encoding, we hypothesized segments and syllable boundaries to be encoded in an incremental way. In a self-monitoring experiment, decisions about the syllable affiliation (first or second syllable) of a…

The relatedness of phonological coding to the articulatory mechanisms in visual word recognition vary in different writing systems. While articulatory suppression (i.e., continuous verbalising during a visual word processing task) has a detrimental effect on the processing of Japanese words printed in regular syllabic Khana script, it has no such…

The purpose of this study was to assess the influence of phonological priming on the speech reaction time (SRT) of children who do (CWS) and who do not (CWNS) stutter during a picture-naming task. Participants were eighteen 3-5-year-old CWS (M = 50.67 months, SD= 11.83 months), matched in age and gender with 18 CWNS (M = 49.44 months, SD = 10.22…

The present paper comprises an overview of techniques using ultrasound in speech (re)habilitation. Ultrasound treatment techniques have been developed for English lingual stops, vowels, sibilants, and liquids. These techniques come from a series of small "n" studies with adolescents and adults with severe hearing impairment, residual…

Converging evidence supports the hypothesis that the most common subtype of childhood speech sound disorder (SSD) of currently unknown origin is genetically transmitted. We report the first findings toward a set of diagnostic markers to differentiate this proposed etiological subtype (provisionally termed "speech delay-genetic") from other…
