No objective group data on speaking rate or speaking duration have been reported on the speech of adventitiously profoundly hearing‐impaired adults. Results of the present study showed that speaking rate, i.e., number of syllables per second, was significantly slower and speaking duration was significantly longer for 25 adventitiously profoundly hearing‐impaired adult male cochlear implant candidates than for 10 normal‐hearing control subjects. The factors of length of time since onset of profound hearing loss and hearing aid use did not significantly affect speaking rate. Based on these objective data, a rationale and method are presented for aural rehabilitation of the profoundly hearing‐impaired who exhibit speaking rate abnormalities.
