Perceptual and Acoustic Properties of Phonemes in Continuous Speech for Different Speaking Rate

Investigations have been made on the perceptual properties of CV-syllables taken out from continuous speech spoken with three different speaking rate. Fifteen short Japanese sentences were spoke by a male speaker with 1) fast speaking rate, 2) normal rate and 3) slow rate. The results reveal that individual syllables do not have enough phonetic information to be correctly identified especially for the fast speech. The average identification of syllables for the fast speech is 35%, 59% for the normal and 86% for the slow. It has been found that syllable perception almost entirely depends on the consonant identification.
