Document Summary
Linguistic properties = info about the speaker"s intended message. Lexical properties = info about the speaker"s voice: describe vowel transformations and why they haven"t worked. Vowel transformation = logarithms of formant frequencies, ratio of formant frequencies, logarithms of ratios of formant frequencies with these we can reduce or eliminate differences due to talker, age, and sex. Haven"t worked because we still get variability and vowels can have the same ratios. What do those results say about cp? categorical perception is not the same in all languages because. Spanish speaker start voicing sooner than english speaker. Speech is special evidence suggests that cp was unique to speech. Adults and infants perceive phonemes categorically, nonspeech sounds are not perceived categorically. Describe the evidence that cp is more general. Cp was unique to speech adults and infants perceive categorically non speech sounds are perceived categorically. Not all phonemes are perceived categorically: stop consonants are, vowels & fricatives are not.
