Abstract
The most common recording of CNC words used to test speech perception by persons with cochlear implants utilizes a single male talker. However, research has shown that CI recipients often have difficulty perceiving speech by persons with high F0 and formant frequencies (Loizou, P., Dorman, M., and Powell, V. 1998. J. Acoust. Soc. Am. 103: 1141–1149). Presented here are CNC word lists recorded using an adult female talker. Ten normal hearing adults identified these words with 99% accuracy. Eight CI subjects also listened to the original (male voice) and new (female voice) recordings. The two star subjects identified the female speakers words 15% less accurately than the male speakers words (Male voice: 82% correct; Female voice: 67% correct). For the other CI subjects (mean performance around 40%) there was no effect of voice on their performance. Results of the acoustic analysis of all the stimuli will also be presented.
