Summary
Seminal quantitative group acoustic data are presented on voice quality changes following electrical stimulation (ES) of the auditory nerve via a single-channel cochlear implant (CI). It was found that the fundamental frequency (Fo) of our patients was significantly lower after the first day of ES, while intensity and speaking duration were not significantly different from pre-CI values. These results suggest that the CI provides enough frequency information < 300 Hz to permit immediate and independent alterations in voice Fo towards normal-hearing speakers values. Our findings also indicate that intensity and speaking duration require additional time before differences found become significant. Longitudinal data are still needed to determine if Fo continues to lower and if intensity and/or speaking duration change significantly to approximate values observed in normal-hearing individuals.
