Voice is not affected in a sensorineural hearing loss • Until the loss exceeds 50 dB in frequencies under 2000 Hz 1、common idea
Voice charateristcs in deaf or profoundly hard of hearing people • Elevated F0 • Varied pitch and loudness changes • Downward formant shifts • Resonance variations • Speech characteristics of those people • Slower rate of speech by prolonging vowels • Variations in the prosody or melody of speech 2、voice characteristics
Voice training for the severely hearing-impaired people should not begin • Until efforts are made to provide needed amplification. 3、management and therapy
3、management and therapy Awareness of voice Soft ware Cue arrows Fingers Visual feedback tactile feedback
