Optimal Training Methods for Lexical Tone Perception by Children with Cochlear Implants: Application of Experimental Psychology Techniques

点击翻译按钮获取中文摘要

Cochlear implants (CIs) stimulate the auditory nerve via electrodes in the cochlear to provide auditory information to people who would otherwise be functionally deaf. Cochlear site stimulation is at a constant rate so, despite the genius of the CI, it cannot convey pitch information effectively. Such information is essential for perceiving and speaking tone languages, in which word meaning depends on consonants, vowels, and tones (conveyed mainly by pitch). A training method to improve tone perception will be developed with non-tone language non-CI through to tone language CI children drawing on experimental psychology methods, auditory and visual (lip & face) speech information, exaggerated tone cues, and metalinguistic instruction.
