Document Summary
Stops/glides /ba/ vs. /wa/ (hillenbrand, et al. , 1979) F1 and f2 formant transition duration differences . Slowly lengthen the transition to get to /wa/ Continuum needed to get from /ra/ to /la/ Adult japanese cannot discriminate /ra/ from /la/ Oral/nasal distinction /ba/ vs. /ma/ (eimas, 1980) Yes, babies can discriminate in a categorical way! Place of articulation for glides /wa/ vs. /ja/ (jusczky et al. , 1978) Infants are as good as adults in coping with speech variability. Babies tested by means of the high amplitude. Tested on english /i/ vowel and swedish /y/ vowel. Swedish /y/ and english /i/ are very different and. Prototype means an ideal representation of a vowel. The speech sounds around the prototype are variations of the prototype. The analysis consisted of comparing the number of sucks babies gave to prototype vowels vs. non-prototype vowels as a function of native vs. non-native. Main effect for native vs nonnative was significant.
