Document Summary

Categorical perception - act of perceiving physically distinct stimuli as identical for a specific purpose, we group several physically distinct speech sounds into a single category. Different individuals create slightly different formant values for the same phoneme. Children must learn the boundaries between phonemes in the continuum. Children acquire phonemes and phonology gradually; hence, children"s utterances are different from adults" utterances. Today"s objective is to look at some data of children"s production and consider how they differ from adults" ways of speaking. Stages of babbling: ba, ma, da (frequently, repetition of the same syllable, ba, bi, da, do, sounds only come from the adult language, words. The data below are from a child named paul at the age of two. Paul has difficulty pronouncing the s" if it is followed by another consonant and instead pronounces the second consonant as the first consonant. He does not have this difficulty when the s" is followed by a vowel.
