目的：为了评估声调知觉的表现，在广东话的语前听力受损的儿童与人工耳蜗implants.Study设计和设置：区分和识别广东话的音调的能力进行了评估，对17个母语为广东话的语前听力受损的儿童。结果：被试在辨别和识别任务中的表现略高于机会水平。虽然音调的轮廓基频的变化为音调辨别提供了一些线索，但这些区别被证明不足以让受试者表现良好。声调6（低水平音）是最难识别的。受试者的表现与性别，植入年龄，植入使用的持续时间，频率的听觉训练会议，或一般的沟通能力。结论：虽然有些儿童能够区分和/或识别粤语声调，他们的表现是穷人。需要进一步的研究来了解音调感知与日常言语理解的关系。意义：可能需要修改耳蜗植入语音编码策略以优化音调感知。
OBJECTIVE: To evaluate tone perception performance in Cantonese-speaking prelingually hearing-impaired children with cochlear implants.STUDY DESIGN AND SETTING: The ability to discriminate and identify Cantonese tones was evaluated on 17 native Cantonese-speaking prelingually hearing-impaired children. Performance was correlated to factors like age of implantation and general communication ability.RESULTS: Subjects' performance in discrimination and identification tasks was slightly above chance level. Although variations in the contour fundamental frequency of the tones provided some cues for tone discrimination, these distinctions proved insufficient for subjects to perform well. Tone 6 (low level tone) was the most difficult to identify. Subjects' performance did not correlate with gender, age of implantation, duration of implant use, frequency of auditory training session, or general communication ability.CONCLUSION: Although some children were able to discriminate and/or identify Cantonese tones, their performance was poor. Further studies are needed to understand how tone perception relate to daily speech understanding.SIGNIFICANCE: Cochlear implant speech coding strategies may need modification to optimize tone perception.
