This experiment investigated the abilities of adults and normal children to imitate normal, lateralized, and retracted fricatives in CV contexts. Distribution measures derived from spectral analyses of the fricative noise were evaluated with respect to subject age, phonetic context and articulatory distortion. The results revealed significant manner/place influences on fricative production as well a trend towards less articulatory precision by the children. Although lateral /s/ was difficult for children, their measurable /s/ distortions were very similar to those of adults.
