Assessing Speech Perception in Children With Cochlear Implants Using a Modified Hybrid Visual Habituation Procedure

Objectives: The objectives of this research were to determine whether
an adapted version of a Hybrid Visual Habituation procedure could be
used to assess speech perception of phonetic and prosodic features of
speech (vowel height, lexical stress, and intonation) in individual preschool-
age children who use cochlear implants.
Design: Nine children ranging in age from 3;4 to 5;5 participated in this
study. Children were prelingually deaf and used cochlear implants and
had no other known disabilities. Children received two speech feature
tests using an adaptation of a Hybrid Visual Habituation procedure.
Results: Seven of the nine children demonstrated perception of at least
one speech feature using this procedure using results from a Bayesian
linear regression analysis. At least one child demonstrated perception of
each speech feature using this assessment procedure.
Conclusions: An adapted version of the Hybrid Visual Habituation
Procedure with an appropriate statistical analysis provides a way to
assess phonetic and prosodicaspects of speech in pre-school-age children
who use cochlear implants.
