British Version of the Iowa Test of Consonant Perception

Abstract

AbstractThe Iowa Test of Consonant Perception (ITCP) is a single-word closed-set speech- in-noise test with well-balanced phonetic features that provides a reliable testing option for real-world listening.Objectives.The current study aimed to establish a UK version of the test (B-ITCP) based on the British received pronunciation.Design.We conducted a validity test with 46 participants using the B-ITCP test, a sentence-in- noise test, and audiogram.Results.The B-ITCP demonstrated excellent test-retest reliability, cross-talker validity, and good convergent validity, consistent with the US results.Conclusions.These findings suggest that B-ITCP is a reliable measure of speech-in-noise perception, to facilitate comparative or combined studies in USA and UK. All materials (application and scripts) to run or construct the B-ITCP and ITCP are freely available online.
