Examines the relationship between phonetic substitution patterns in child speech and sound change patterns in dialects of adult language, basing an explanation of these phenomena on acoustic data and language universals. (AM)

Examined the phonological memory capacity, rate of articulation, phonological encoding, and perceptual-processing abilities of 13 specifically language-impaired (SLI) children and 13 language-matched normal (NL) children. The results of a nonsense word repetition task showed that SLI children repeated significantly fewer multisyllabic nonsense…

The errors on word-initial consonant clusters made by children (ages 2-9) in the Iowa-Nebraska Articulation Norms Project were tabulated by age range and frequency. Error data showed support for previous research in the acquisition of clusters. Cluster errors are discussed in terms of theories of phonologic development. (Author/JDD)

Presents findings from the first phase of a longitudinal study examining the development of articulation quality and specific phoneme awareness during the fourth year of life. Articulation and phoneme awareness of /r/ and a control phoneme were assessed for 80 3-year-old children. (Author/JL)

A study examined the role of phonological regression in the language learning patterns of two toddlers. The children's phonological development was measured by inventories of the words produced at the beginning and end of an eight-week period, and distinctions were made between regressions due to cognitive factors and those due to non-cognitive…

Three linguistic studies of Philippine languages are presented. In "Sociolinguistic Survey of Bantoanon" by M. Ruth Gordon and Heather J. Kilgour, sociolinguistic methods were used to study the Bantoanon area of northwest Ramblon province to learn how the Bantoanon people feel about their language and where its linguistic center is.…

A question of both theoretical and practical importance for the study of phonological development is whether there is a difference in the status of productions rendered spontaneously by the child and those repeated by the child after either an adult model or his own production. The relevant theoretical questions are: (1) Are all the child's…

This is a report on the deviant phonological system of a 4-year-old child. Although this system is characterized by deletions, assimilations, simplifications, and distortions, there is a regularity in the system which lends itself to systematic phonological analysis. Based on an examination of sample phonological deviations, the following rules…

The pronunciations of children do not merely represent accidental misses with respect to adult pronunciation. Children employ substitutions and deletions in highly systematic ways; child pronunciations reflect a set of simplification strategies. The major common processes of both normal and abnormal child phonology result in simplification of…

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 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…
