A comparison of subjective speech intelligibility tests in reverberant environments

K. Kruger, K. Gough, P. Hill

Abstract


This study compared intelligibility scores for three subjective test methods against a wide range of reverberant conditions. The three subjective methods were the CID phonetically balanced word test, modified rhyme test and CID test sentences. Reverberation times varied from approximately 1 second to 6 seconds. Other aspects, not typically explored in previous studies, included a rating scale of difficulty, a measure of the subjects comprehension of speech, and a phonemic analysis of phonetical balanced wordlist errors
