title: Longitudinal effects of single-channel cochlear implantation on voice quality.
abstract: No studies have reported longitudinal group data on the voice characteristics of adult participants with adventitious profound sensorineural hearing loss before and after single-channel cochlear implantation. This study investigated voice fundamental frequency, intensity, and speaking duration preimplantation and longitudinally 1-day, 6-months, and 1-year poststimulation. Results revealed only fundamental frequency 1-day poststimulation to be significantly different from preimplantation. Trends for all three variables, i.e., lowered Fo, reduced intensity, and shortened speaking duration (a faster rate), however, moved toward the measures that typify normal-hearing speakers.
