The experiment investigated the effects of lingual coarticulation in the speech stimuli of five adults and 14 children. CV syllables ([ki], [ka]) were analysed both acoustically and perceptually to determine the effect of the vocalic environment on the preceding velar stop consonant. In the acoustic analyses, short-time spectra were computed for each consonantal stimulus. Perceptual tests were then conducted by presenting the initial burst portion of the [ki] and [ka] syllables to adult subjects for identification. The acoustic results indicate that the adult stimuli, as expected, show significant coarticulatory effects. In the child data, however, the differences between the velar stops preceding front and back vowels are not always present. Moreover, the perceptual data show that the coarticulatory cues in the adult stimuli are perceptually salient but that these cues are not as perceptible in some of the children's stimuli. The results are discussed in terms of their implications for language learning.
