Speaking fundamental frequency of postlingually profoundly deaf adult men.

We investigated the speaking fundamental frequency (F0) of 21 postlingually profoundly sensorineurally deaf men. Results indicated that speaking F0 was significantly higher for the deaf group than for normal-hearing, age-matched men. Neither duration of profound deafness nor hearing aid usage affected speaking F0 values significantly. The findings of the present study provide a baseline for determining the effects of rehabilitation.
