This investigation determined whether the signal provided by the Cochlear Corporation Nucleus cochlear implant can convey enough speech information to induce a response to delayed auditory feedback (DAF), and whether prelingually deafened children who received a cochlear implant relatively late in their speech development are susceptible. Ten children with the Nucleus cochlear implant spoke simple phrases, first without and then with DAF. Three prelingually deafened subjects and the only two postlingually deafened subjects demonstrated longer phrase durations when speaking with DAF than without it. Two of the prelingually deafened subjects who demonstrated a response received their cochlear implants at the age of 5 years.
本研究确定了科利耳公司的 Nucleus 人工耳蜗所提供的信号是否能够传达足够的语音信息，以引发对延迟听觉反馈（DAF）的反应，以及在言语发展过程中相对较晚接受人工耳蜗植入的语前聋儿童是否易受影响。十名植入 Nucleus 人工耳蜗的儿童先在无 DAF 的情况下、然后在有 DAF 的情况下说出简单短语。三名语前聋受试者以及仅有的两名语后聋受试者在有 DAF 时说话的短语持续时间比无 DAF 时更长。两名表现出有反应的语前聋受试者在 5 岁时接受了人工耳蜗植入。
