Currently there are few standardized speech testing materials for Mandarin-speaking cochlear implant (CI) listeners. In this study, Mandarin speech perception (MSP) sentence test materials were developed and validated in normal-hearing subjects listening to acoustic simulations of CI processing. Percent distribution of vowels, consonants, and tones within each MSP sentence list was similar to that observed across commonly used Chinese characters. There was no significant difference in sentence recognition across sentence lists. Given the phonetic balancing within lists and the validation with spectrally degraded speech, the present MSP test materials may be useful for assessing speech performance of Mandarin-speaking CI listeners.
目前，针对普通话使用的人工耳蜗（CI）使用者，几乎没有标准化的言语测试材料。在本研究中，我们开发并验证了普通话言语感知（MSP）句子测试材料，该材料由正常听力受试者使用 CI 处理的声学模拟进行测试。每个 MSP 句子列表中的元音、辅音和声调的百分比分布与常见汉字中观察到的分布相似。句子列表之间的句子识别没有显著差异。鉴于列表内的语音平衡以及对频谱失真语音的验证，本 MSP 测试材料可能有助于评估普通话使用的 CI 使用者的言语表现。
