Multimodal perception of Mandarin tone for cochlear implant users
Due to limitations of cochlear implant (CI) technology in transmitting fundamental frequency (f0), there is poor perception of lexical tone by CI users. Here simulated cochlear implant audio is used to investigate the role of visual speech information in Mandarin tone discrimination. Results showed that visual information improved tone perception in both Mandarin and Australian English listener...
متن کاملLexical tone perception with HiResolution and HiResolution 120 sound-processing strategies in pediatric Mandarin-speaking cochlear implant users.
OBJECTIVES Lexical tone recognition tends to be poor in cochlear implant users. The HiResolution (HiRes) sound-processing strategy is designed to better preserve temporal fine structure, or the detailed envelope information, of an acoustic signal. The newer HiRes 120 strategy builds on HiRes by increasing the amount of potential spectral information delivered to the implant user. The purpose of...
متن کاملContribution of bimodal hearing to lexical tone normalization in Mandarin-speaking cochlear implant users.
Native Mandarin normal-hearing (NH) listeners can easily perceive lexical tones even under conditions of great voice pitch variations across speakers by using the pitch contrast between context and target stimuli. It is however unclear whether cochlear implant (CI) users with limited access to pitch cues can make similar use of context pitch cues for tone normalization. In this study, native Ma...
متن کاملMelodic contour identification and music perception by cochlear implant users.
Research and outcomes with cochlear implants (CIs) have revealed a dichotomy in the cues necessary for speech and music recognition. CI devices typically transmit 16-22 spectral channels, each modulated slowly in time. This coarse representation provides enough information to support speech understanding in quiet and rhythmic perception in music, but not enough to support speech understanding i...
متن کاملMusical pitch and lexical tone perception with cochlear implants.
OBJECTIVE The purpose of the present study was to test the hypothesis that cochlear implant (CI) users' music perception is correlated with their lexical tone perception, and the two types of perception share similar mechanisms in electric hearing. DESIGN A lexical tone perception test and a pitch interval discrimination test were administered to a group of CI users and a group of normal-hear...
