Corner frequencies for analysis band filters used in cochlear implant simulation.
Voice gender identification scores for CI and NH listeners. The left panels [(a) and (c)] show results for Talker Set 1 and the right panels [(b) and (d)] show results for Talker Set 2. In all panels, individual CI results (open symbols) are shown for performance with clinically assigned speech processors. Mean NH listener data are shown for spectrally matched speech in the top panels [(a) and (b)] and spectrally shifted speech in the bottom panels [(c) and (d)], as a function of the number of channels; the closed symbols show performance for the different envelope cut-off frequency conditions. Error bars indicate standard deviation. N22, N24, MelEL, and CII refer to data from CI patients using the Nucleus-22, Nucleus-24M, MedEL , and Clarion CII implant devices, respectively.
Relevant information for cochlear implant subjects who participated in the experiment.
Acoustic measures for each talker in Talker Sets 1 and 2. F0 is the fundamental frequency, F1, F2, and F3 refer to the lowest three formant frequencies, respectively, and VTL refers to vocal-tract length. Note that the formant frequency measurements are for the vowel ∕ε∕ as in “head” only.
