Abstract

Most of the languages in the world are tonal. In a tonal language, voice pitch variation (i.e., tone) at the syllable level is a segmental structure that conveys lexical meaning of words. Multichannel cochlear implants (CIs) have shown great success in providing profoundly-deafened individuals with satisfactory speech perception in quiet. However, contemporary speech-processing strategies used in CIs do not explicitly code pitch information. This presentation will be focused on (1) acoustic cues for recognition of lexical tones, primarily the Mandarin Chinese tones, and the relative contributions of various cues to tone recognition, (2) results of tone recognition experiments in implant recipients in relation to their differences in demographics, devices, strategies, and psychoacoustic abilities, (3) relationship between music pitch perception and lexical tone recognition, and (4) results on tone production and vocal singing in prelingually-deafened, native tonal-language speaking children with CIs.
