Tone languages differ from English in that the pitch pattern of a single-syllable word conveys
lexical meaning. In the present study, dependence of tonal-speech perception on features of
the stimulation was examined using an acoustic simulation of a CIS-type speech-processing
strategy for cochlear prostheses. Contributions of spectral features of the speech signals
were assessed by varying the number of filter bands, while contributions of temporal
envelope features were assessed by varying the low-pass cutoff frequency used for …
