Child speech is highly variable. The speech apparatus--the vocal tract, tongue, teeth, and vocal folds--develop at different rates for different children, which helps explain some of the variability in children's speech. For example, the ratio of the oral to pharyngeal cavities changes as children age, making it difficult to establish reliable…

This longitudinal case study documents the emergence of bilingualism in a young monolingual Mandarin boy on the basis of an acoustic analysis of his vowel productions recorded via a picture-naming task over 20 months following his enrollment in an all-English (L2) preschool at the age of 3;7. The study examined (1) his initial L2 vowel space, (2)…

This study focuses on a trilingual toddler's ability to differentiate her Tagalog, Spanish and English productions on phonological/phonetic grounds. Working within the articulatory phonology framework, the word-initial segments produced by the child in Tagalog, Spanish and English words at age 1;10 were narrowly transcribed by two researchers and…

Purpose: Significant challenges face speech-language pathologists when children raised in bilingual environments are referred for speech-language evaluations. The situation is compounded for bilingual Mandarin-English children because no research-based data is available to date. This study is a preliminary examination of phonological acquisition…

This paper reports the results of a longitudinal case study examining the acquisition of the English voice system by a three-year-old native speaker of Dutch. The study aims to examine whether the child develops two different phonetic systems or uses just one system for both languages, and compares the early L2 acquisition process with L1,…

This paper is concerned with a specific case of L3 acquisition: the starting position for English vowel acquisition by infant German-Italian bilinguals will be investigated in light of prototype theory. The chosen example of triple language contact is characterised by consecutive bilingualism as the basis of L3 acquisition, where the learners' L2…

This article discusses the problems encountered by second language learners in mastering the phonology of the target language, and suggests the use of music in second language teaching, particularly for intonation. (Text is in French.) (CLK)

This volume contains the papers read at the Conference on Language and Language Behavior held at the University of Michigan's Center for Research on Language and Language Behavior in October 1966. Papers are ordered under the following topics: First Language Acquisition in Natural Setting, Controlled Acquisition of First Language Skills, Second…

Behavioral data establish a dramatic change in infants' phonetic perception between 6 and 12 months of age. Foreign-language phonetic discrimination significantly declines with increasing age. Using a longitudinal design, we examined the electrophysiological responses of 7- and 11-month-old American infants to native and non-native consonant…

This paper reports on a study in which twenty young adults were tested for their ability to accurately reproduce the articulatory and prosodic features of three non-Indo-European languages in which they had received instruction. The first of two basic goals of this research was to test, at the purely phonetic level, the "critical period for…

Videotape is much like audio tape in that it is magnetic tape on which a signal is electronically recorded, but it carries both an audio and a video signal. Video equipment demands a rather large initial expense but tape is relatively inexpensive. The magnifying, dynamic and synthesizing properties of this medium lend themselves to meeting some…

This volume is a collection of articles on various aspects of applied linguistics as it relates to language teaching. Chapter 1, by S. Pit Corder, entitled "Applied Linguistics and Language Teaching," gives a short, general survey of applied linguistics in language teaching. Chapters 2-5 give an account of the main concepts in what is now called…

Fifty-three papers on linguistic theory and language research, including a number of prize-winning essays, address these topics: aspects of discourse analysis; bilingualism; Chinese modal verbs; early bilingual speech; linguistic metatheory; music and accent discrepancy; diphthongs; hiatus; vowel patterns; suprasegmentals; neologisms; aspects of…
