The goal of this project is to investigate the phonological systems of prelingually profoundly deafened children after long- term use of cochlear implants. Previous research has demonstrated that cochlear implants can be an effective device for promoting both speech perception and speech production in children with profound hearing impairment. However, because of the relatively recent introduction of cochlear implants as a treatment option for pediatric patients, speech production has not been assessed much beyond three years of device use. Using methods and techniques from clinical linguistics, the proposed project will provide detailed information regarding the phonological knowledge and underlying linguistic systems of ten children who have used cochlear implants for a much longer time, at least five years. The proposed project will therefore provide for the first time detailed information about the phonological systems that long-term users of cochlear implants actually develop, information about the differences between these systems and the target system, and information about directions of development and change in these systems. Data from this study will provide important new knowledge regarding the way in which language can develop using a type of auditory input (electrical stimulation) that is unique in the history of humankind. Specifically, it will provide new information about how this type of auditory input can facilitate the development of phonological systems similar to target phonological systems.

本研究的目的是研究长期使用人工耳蜗后的语前深度耳聋儿童的语音系统。先前的研究表明，人工耳蜗是促进重度听力障碍儿童语言感知和语言产生的有效手段。然而，由于耳蜗植入作为儿科患者的一种治疗选择相对较新，使用该设备三年后，对语音产生的评估并不多。利用临床语言学的方法和技术，该项目将提供10名使用人工耳蜗更长时间（至少5年）的儿童的语音知识和潜在语言系统的详细信息。因此，拟议的项目将首次提供长期人工耳蜗使用者实际发展的语音系统的详细信息，这些系统与目标系统之间的差异的信息，以及这些系统的发展和变化方向的信息。这项研究的数据将提供重要的新知识，关于语言是如何利用人类历史上独一无二的一种听觉输入（电刺激）发展的。具体来说，它将提供关于这种类型的听觉输入如何促进与目标语音系统相似的语音系统的发展的新信息。
