Abstract

© 2024 Author(s). The Iowa Test of Consonant Perception is a single-word closed-set speech-in-noise test with well-balanced phonetic features. The current study aimed to establish a U.K. version of the test (ITCP-B) based on the Southern Standard British English. We conducted a validity test in two sessions with 46 participants. The ITCP-B demonstrated excellent test-retest reliability, cross-talker validity, and good convergent validity. These findings suggest that ITCP-B is a reliable measure of speech-in-noise perception. The test can be used to facilitate comparative or combined studies in the U.S. and U.K. All materials (application and scripts) to run the ITCP-B/ITCP are freely available online.
