Document Summary

We understand other people"s speech from speech perception and spoken word recognition. Speech perception - process by which the sounds of language are heard, interpreted and understood. Speech is dynamic and continuous but ipa symbols are static and cannot represent everything. Duration of a sound: vowel duration, vot, etc. Spectral properties: pitch, resonant frequencies, amplitude, etc. Spectral transitions from one sound to another. Participants however couldn"t detect that a sound was missing. They appear to restore the /s/ phonemes to the word (cid:824)legislatures(cid:825) they continue to report the deleted phoneme is perceptually restored even if it"s missing. The english words "lag" and "rag" would sound the same to non native english speakers. A phenomenon of perception in which an individual sorts continuous stimuli into stimulus categories. Occurs when items that range along a continuum are perceived as being either more/less similar to each other than they are b/c of the way they"re categorized.
