Abstract
Background Considerable variability exists in the speech recognition abilities achieved by children
with cochlear implants (CIs) due to varying demographic and performance variables
including language abilities.
Purpose This article examines the factors associated with speech recognition performance
of school-aged children with CIs who were grouped by language ability.
Research Design This is a single-center cross-sectional study with repeated measures for subjects
across two language groups.
Study Sample Participants included two groups of school-aged children, ages 7 to 17 years, who
received unilateral or bilateral CIs by 4 years of age. The High Language group (N = 26) had age-appropriate spoken-language abilities, and the Low Language group (N = 24) had delays in their spoken-language abilities.
Data Collection and Analysis Group comparisons were conducted to examine the impact of demographic characteristics
on word recognition in quiet and sentence recognition in quiet and noise.
Results Speech recognition in quiet and noise was significantly poorer in the Low Language compared with the High Language group. Greater hours of implant use and better adherence to auditory-verbal (AV)
therapy appointments were associated with higher speech recognition in quiet and noise.
Conclusion To ensure maximal speech recognition in children with low-language outcomes, professionals
should develop strategies to ensure that families support full-time CI use and have
the means to consistently attend AV appointments.
