Abstract
The correlation between ripple spectrum resolution and speech recognition in prelingual and postlingual cochlear implant users was analysed. The test signal had a band-limited rippled spectrum with a bandwidth of 2 octaves. The central frequency of the spectrum was 1, 2, or 4 kHz. The ripple phase reversion test of was used for estimation of ripple spectrum discrimination. A balanced test set of Russian worlds by Greenberg–Zinder was used for estimating the speech recognition. The average ripple discrimination thresholds were approximately 2 ripples/oct in both pre- and postlingual patients. The thresholds did not depend on the central frequency. The best correlation between speech recognition and rippled spectrum resolution was found in the prelingual patients with a perimodiolar electrode array (r = 0.85).
