PURPOSE This study investigated formant frequencies for their role as acoustic and perceptual correlates to the place of articulation of Cantonese final stops produced by profoundly hearing impaired speakers. METHOD Speakers were 10 Cantonese adolescents (mean age=13;5 [years;months]) who were profoundly hearing impaired (HI). Control speakers were 10(More)
This study investigated the role of Voice Onset Time (VOT) as perceptual cue to the aspiration contrast of Cantonese initial stops produced by adolescent profoundly hearing impaired speakers. Speakers with normal hearing signalled the aspiration contrast through VOT differences. Hearing impaired speakers produced initial stops with no significant VOT(More)
OBJECTIVE This study investigated five acoustic parameters of fundamental frequency (f0), one related to average f0 level and four related to change of f0 (f0 change) over four consecutive quarters of the vocalic segment, for their roles as acoustic correlates to the perception of Cantonese lexical tones produced by profoundly hearing-impaired speakers.
