Intelligibility scores obtained with the Modified Rhyme Test (MRT), Oklahoma University Closed-Response Test (OUCRT), and the California Consonant Test (CCT) were compared. The word lists were recorded by a male speaker with general American English dialect. Twenty-four normal-hearing subjects heard the three lists monaurally at most comfortable loudness level. Four listening conditions, namely, lowband (100–1500 Hz), highband (2000–6000 Hz), speech-in-noise (S/N ratio = 0 dB), and wideband (100–6000 Hz) were employed. The mean intelligibility scores for the three lists across the four listening conditions ranged from 99.2% through 45.3%. An analysis of these findings from practical considerations will be discussed.
