Modified Rhyme Test (MRT)

A word list for statistical intelligibility testing. The modified Rhyme Test uses 50 six-word lists of rhyming or similar-sounding monosyllabic English words, as shown here. Each word is constructed from a consonant-vowel-consonant sound sequence, and the six words in each list differ only in the initial or final consonant sound. Listeners are shown a six-word list and then asked to identify which of the six is spoken by the talker. A carrier sentence is usually used.

MRT test results indicate errors in discrimination of both initial and final consonant sounds. Listener responses can be scored as (1) the number of words heard correctly; (2) the number of words heard incorrectly; or (3) the frequency of particular confusions of consonant sounds.
