Abstract
The developmental use of vowel duration, final transition and voicing during closure as cues to voicing in final stop consonants were investigated, using 10 three-year-old, 10 six-year-old and 10 adult subjects. The stimuli were alterations of eight stop-vowel-stop words. The presentation of each stimulus item was response contingent. The resulting data supported the ability of adults and children to use both temporal and spectral cues to acoustic/ phonetic distinctions. However, three-year olds relied more on temporal cues, six-year olds relied more on spectral cues, while adults used both spectral and temporal cues in judging the voicing feature of final stop consonants.
