Lexical 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 کاملMultimodal 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 کاملMusic Training Can Improve Music and Speech Perception in Pediatric Mandarin-Speaking Cochlear Implant Users
Due to limited spectral resolution, cochlear implants (CIs) do not convey pitch information very well. Pitch cues are important for perception of music and tonal language; it is possible that music training may improve performance in both listening tasks. In this study, we investigated music training outcomes in terms of perception of music, lexical tones, and sentences in 22 young (4.8 to 9.3 ...
متن کاملEvaluation of the ClearVoice Strategy in Adults Using HiResolution Fidelity 120 Sound Processing
OBJECTIVES This study aimed to evaluate the benefits of ClearVoice strategy on speech perception in noise and in everyday listening situations in Cantonese-speaking cochlear implant users. METHODS Twelve experienced adult users of the Harmony implant and HiRes 120 sound processing participated in the study. The study employed a prospective within-subjects design wherein speech recognition in ...
