This paper reviewed the literature on the development of and factors affecting speech perception of Mandarin-speaking children with cochlear implantation (CI). We also summarized speech outcome measures in standard Mandarin for evaluating auditory and speech perception of children with CI. A comprehensive search of Google Scholar and PubMed was conducted from March to June 2021. Search terms used were speech perception/lexical tone recognition/auditory perception AND cochlear implant AND Mandarin/Chinese. Unilateral CI recipients demonstrated continuous improvements in auditory and speech perception for several years post-activation. Younger age at implantation and longer duration of CI use contribute to better speech perception. Having undergone a hearing aid trial before implantation and having caregivers whose educational level is higher may lead to better performance. While the findings that support the use of CI to improve speech perception continue to grow, much research is needed to validate the use of unilateral and bilateral implantation. Evidence to date, however, revealed bimodal benefits over CI-only conditions in lexical tone recognition and sentence perception in noise. Due to scarcity of research, conclusions on the benefits of bilateral CIs compared to unilateral CI or bimodal CI use cannot be drawn. Therefore, future research on bimodal and bilateral CIs is needed to guide evidence-based clinical practice.
本文回顾了有关汉语人工耳蜗植入（CI）儿童言语感知发展及影响因素的文献。我们还总结了用于评估CI儿童听觉和言语感知的标准普通话言语结果测量方法。于2021年3月至6月对谷歌学术和PubMed进行了全面检索。使用的检索词为言语感知/声调识别/听觉感知 以及 人工耳蜗 以及 普通话/中文。单侧CI接受者在开机后的几年里听觉和言语感知持续改善。植入时年龄较小以及CI使用时间较长有助于更好的言语感知。植入前接受过助听器试验且照顾者教育水平较高可能会带来更好的表现。虽然支持使用CI改善言语感知的研究结果不断增加，但仍需要大量研究来验证单侧和双侧植入的使用。然而，迄今为止的证据表明，在声调识别和噪声中的句子感知方面，双模式比仅使用CI有更多益处。由于研究较少，无法得出关于双侧CI与单侧CI或双模式CI使用相比的益处的结论。因此，需要对双模式和双侧CI进行未来研究，以指导循证临床实践。
