PHONOLOGICAL SYSTEMS AFTER LONGTERM COCHLEAR IMPLANT USE

本研究的目的是探讨长期使用人工耳蜗后，语前深度退化儿童的语音系统。 先前的研究已经证明，人工耳蜗植入可以是一种有效的设备，以促进语言感知和语言产生的儿童有深刻的听力障碍。 然而，由于相对较新引入的人工耳蜗植入作为儿科患者的治疗选择，言语产生没有被评估超过三年的设备使用。 使用临床语言学的方法和技术，拟议的项目将提供有关语音知识和基本语言系统的详细信息，这些儿童使用人工耳蜗植入的时间要长得多，至少五年。 因此，拟议的项目将首次提供有关人工耳蜗长期使用者实际发展的语音系统的详细信息，有关这些系统与目标系统之间差异的信息，以及有关这些系统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，关于语言可以使用人类历史上独一无二的听觉输入（电刺激）来发展的方式。具体来说，它将提供新的信息，这种类型的听觉输入如何促进语音系统的发展类似于目标语音系统。

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.
