A classification and description of cry types stimulated by different internal sources--hunger, pain, illness and alarm. Various features of each type were distinguished by spectrographic analysis. Pain cries seemed to be the basic type from which other types evolve. Comparisons with other studies were made. (AMH)

This study constitutes the beginning of a longitudinal investigation of phonological development of four children from birth to 2 years. Little variation was found in mean fundamental frequency. Duration, within-utterance range and variability did show developmental change. (RM)

Using Locke's 1983 model, analyzes one tendency, consonant use in babbling and early words, and phonological word-selection patterns in 10 children, aged 8 to 16 months. Individual differences were found in all three domains analyzed, with some increase in uniformity across subjects with increasing knowledge of language. (Author/SED)

A study of the babbling and phonological development of 54 infants used half-hour videotape recordings of the children at play in their own homes. The vocal output was phonetically transcribed twice for interrater agreement, and analyzed for the consonants used five times or more in the child's vocal repertoire. These consonants were considered to…

The first part of this bibliography contains annotations of articles on the acquisition of voice onset time (VOT) as the marker of a phonological contrast, that is, the studies concern children who are already developing a phonological system. The most common questions are the following: (1) When children begin to produce initial stops, how are…

A case study analyzed the babbling and speech production of an infant, aged 20 to 24 months, whose family members spoke Portuguese, English, and French interchangeably. Focus was on vowel production, choice of lexicon, and the relationship between babbling and speech in the interaction of his languages. The child's utterances were recorded in…

One of the most remarkable aspects of the babbling of some babies is that it is produced with intonation contours that sound very much like adult sentence melodies. This study reviews the literature and examines longitudinal data collected from seven children. Some of the non-adult-like syntactic uses made of intonation by children for…
