dc.description.abstractA new speech-processing strategy has been developed for the Cochlear Pty. Ltd. 22-electrode cochlear prosthesis which codes an estimate of the first formant frequency in addition to the amplitude. voice pitch and second formant frequencies. Two groups of cochlear implant patients were tested 3 months after implant surgery, one group (n= 13) having used the old (F0F2) processing strategy and the other (n=9) having used the new (F0FIF2) strategy. All patients underwent similar postoperative training programs. Results indicated significantly improved speech recognition for the F0FIF2 group particularly on open set tests with audition alone. Additional testing with a smaller group of patients was carried out with competing noise (speech babble). Results for a closed set spondee test showed that patient performance was significantly degraded at a signal-to-noise ratio of 10 dB when using the F0F2 strategy, but was not significantly affected with the F0FIF2 strategy.en_US
