Young cochlear implant users' response to delayed auditory feedback.
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.
