In my dissertation, I examine four notation systems used to represent hand configurations in child acquisition of signed languages. Linguists have long recognized the descriptive limitations of Stokoe notation, currently the most commonly used system for phonetic or phonological transcription, but continue using it because of its widespread…

In her interesting article, Stoel-Gammon (this issue) reviews studies concerning the interactions between lexical and phonological development. While the focus of the review is on vocabulary production from children acquiring American English, she also suggests that cross-linguistic research be undertaken to examine how universal and…

Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

Reports on an experiment, conducted on ten children who misarticulated /s/, and designed to survey the effect of consonant context on misarticulation. Suggests that a context-sensitive model of phonetic performance is needed to account for variation in correct /s/ production. (Author/AM)

Analyzes early lexical and phonological development in three children from late babbling through the acquisition of 50 conventional words. Focuses on (1) the relationship between prelinguistic and linguistic vocalizations, (2) phonological development after the onset of speech, (3) patterns of lexical selection, (4) rate of lexical acquisition,…

Describes acoustic analysis of the speech of a child from 46 to 149 weeks in which overall word duration, pitch perturbation, and within-word phonetic segments were measured. The subject's overall word duration decreased considerably at a relatively late stage, supporting the claim that a child's neuromuscular control improves with maturation.…

Describes vocalizations of five 13-month-old infants. Data are reported on syllable shape, vowel-like and consonant-like production in context and time, periodic utterances, complex babbling sequences, recurrent phonetic forms, fundamental frequency, and intonation types. Results are consistent with data from other studies and support theory of…

Reports on an experiment which sought to compare child and adult speech in terms of (1) stop productions evidencing devoicing during consonant closure, and (2) consonant closure evidencing voicing in the case of devoiced stops. (Author/AM)

This paper reports on an investigation of the voice-onset-time (VOT) characteristics of word-initial stops produced by four four-year-old children. Instrumental analysis of the children's spontaneous speech showed that they had distinct distributions for voiced and voiceless stops at all three places of articulation and that there was very little…

Children and adults participated in two speech perception experiments in which they listened to recorded consonant-vowel-consonant (CVC) words in random order and resPonded by indicating which number of a word-pair they had heard. Some but not all stimuli that were intended to induce perceptual cross-over were successful in getting subjects to…

Describes a study that examined the organization inherent in children's misarticulations of final consonant sounds. Specifically, it inquired whether, when children with final stop and fricative omissions are taught to produce either stops or fricatives in word-final positions, generalization occurs to untaught items or only to taught items.…

Presents the results of a study of attention as a factor in children's natural and experimental acquisition of articulatory behavior. (TO)

Assesses the relationship between production deficits and speech perception abilities. A categorical perception paradigm was administered to a group of communication disordered children and to a matched control group. Group results are tentatively interpreted as showing a moderate perceptual deficit in the communication disordered children of this…

Examines the phonetic patterns and linguistic development of an infant who was tracheostomized during the period that infants normally begin to produce syllabic vocalization. It was found that the infant had developed only a tenth of the canonical syllables expected in normally developing infants, a small inventory of consonant-like segments, and…

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,…
