Abstract

The Iowa Test of Consonant Perception (ITCP) was designed to test word-initial phoneme perception by uniformly sampling frequently used phonemes as well as balancing feature overlap of response competitors. However, the task has only been validated in normal hearing listeners. In this study, a large cohort of cochlear implant users completed the ITCP and two commonly used clinical measures of speech recognition [AzBio sentences and consonant-nucleus-consonant (CNC) words]. At two different signal-to-noise ratios, the ITCP showed strong convergent validity with other speech recognition tasks and good test-retest reliability. The ITCP is a useful tool for both clinicians and experimental researchers.
