The current study examined the relation between speaking-style categorization and speech recognition in post-lingually deafened adult cochlear implant users and normal-hearing listeners tested under 4- and 8-channel acoustic noise-vocoder cochlear implant simulations. Across all listeners, better speaking-style categorization of careful read and casual conversation speech was associated with more accurate recognition of speech across those same two speaking styles. Findings suggest that some cochlear implant users and normal-hearing listeners under cochlear implant simulation may benefit from stronger encoding of indexical information in speech, enabling both better categorization and recognition of speech produced in different speaking styles.
本研究考察了在 4 通道和 8 通道声码器人工耳蜗模拟条件下，对成年后天聋的人工耳蜗使用者和正常听力者的言语风格分类与言语识别之间的关系。在所有的听众中，仔细阅读和随意交谈这两种言语风格的说话者分类越准确，对这两种言语的识别也越准确。研究结果表明，在人工耳蜗模拟条件下，一些人工耳蜗使用者和正常听力者可能受益于言语中索引信息的更有效编码，从而更好地对不同言语风格的言语进行分类和识别。
