ABSTRACT
This brief study has two essential aims. First, it is directed toward the measurement
of changes in voice control that may be consequent on the overnight deactivation of
cochlear implants (CIs) by individual young children in a residential school for the
deaf. Second, the work is based on the exploratory use of a set of voice analytic
procedures that, although developed in the first instance for work on connected speech
with hearing-impaired children, have subsequently been applied extensively in voice
clinic environments. Acoustic and electrolaryngograph speech recordings have been
made and analyzed for a group of children with CIs, early in the morning with acoustic
and CI aids switched off and at the end of a normal day's use. Special attention has
been paid to the analysis of perceptually relevant physical aspects of pitch, intonation,
and voice quality. Differences in voice control between these conditions of implant
use have been found for all of the children.
