Ten mothers and 20 children, aged 5 and 10 years, were examined to determine the time at which velopharyngeal port opening began in /dVn/ syllables and velopharyngeal port closing reached completion in /nVd/ syllables. Adults and children nasalized most vowels in the /dVn/ context and the /nVd context. (Author/JDD)

This is a report on an investigation of the correct production of /s/ in spontaneous speech of children. A greater incidence of incorrect production was found for pre-boundary /s/ than for /s/ in other lexical positions. Lexical position is related to articulatory inconsistencies in child speech. (SC)

This research report examines the pronunciation that children give to synthetic words containing vowel-cluster spellings and analyzes the observed pronunciations in relation to common English words containing the same vowel clusters. The pronunciations associated with vowel-cluster spellings are among the most unpredictable letter-sound…

Irregularities in oral fluency, or "disfluencies," are common in the speech habits of both children and adults. Disfluencies can take the form of hesitations, revisions, repetitions, or interjections. Most disfluenceies do not occur at random, but are directly linked to other factors such as verbal planning--the combination of decisions…

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 study is concerned with misarticulated speech sounds of children and the phonetic realization of these sounds. The articulation errors of 384 standard-English-speaking school children were analyzed in speech samples obtained by the National Speech and Hearing Survey and were samples of both free speech and of performance on the…
