人工耳蜗植入（cochlear implant, CI）是重度、极重度感音神经性聋听力重建的重要方法。CI可以提供理想听力环境下较好的言语识别，然而由于频谱分辨率的不足和以及精细结构信息的缺乏，CI植入者对真实听力环境中韵律信息和索引信息的感知仍有较大的困难。前期研究表明真实环境下的言语训练对CI植入者的言语感知具有积极影响，本研究通过探索韵律信息及索引信息对汉语普通话CI植入者真实环境下言语识别的影响，阐明汉语普通话CI植入者真实环境下言语感知机理。拟对汉语普通话CI植入者进行包含韵律信息和索引信息的言语训练，以探索提高汉语普通话CI植入者真实环境下言语感知能力的方法，以期为汉语普通话CI植入者提供新的言语康复策略。

Cochlear implant(CI) is an important method for hearing reconstruction in severe to very severe sensorineural deafness. Currently, cochlear implant can result in good speech recognition performance in quiet environments. However, the reduced spectral resolution and lack of fine-structure cues, CI users have difficulty perceiving prosodic and indexical information, resulting in the poor real-world speech perception by far. Previous studies have shown that speech training in the real-world may have positive effect on the real-world speech perception of CI users. Thus, we will explore the effects of prosodic and indexical information on Mandarin-speaking CI users’ perception of real-world speech in order to further illuminate the speech perception mechanism of Mandarin-speaking CI users. Meanwhile, we will explore approaches toward improving Mandarin-speaking CI users’ understanding of real-world speech through training with prosodic and indexical information, in order to provide new speech rehabilitation strategies.
