Determined how proficiently children identify gender of adults and children, based on whispered and phonated vowels. Compares performance with adult listeners. Both groups obtained simiiar average rates of accuracy when identifying gender based on preadolescent children's phonated vowels. Adults were more accurate when perceiving whispered vowels.…

Investigates the principles underlying the perception of vowel stimuli. The results support Chistovich's claim. When judging the distance between synthetic vowel stimuli, speakers refer to the phonemic structure of their native language. They determine the phonemes closest to the stimuli and then compare the phonemes and not the stimuli…

Electromyographic experiments were performed indicating that durational differences between vowels that precede voiced consonants and those that precede voiceless ones are due to a sustention of muscular activity in articulation, which occurs only with vowels preceding voiced consonants. (SC)

Investigates the effects of morphological boundaries and the voicing characteristics of the following consonant on the duration of stressed vowels produced by hearing impaired adults. They do not vary the duration of stressed vowels in accordance with the durational recording observed in normal speech; however, this deviance is systematic. (PMJ)
