Rhyming word lists isolate consonant confusion as the measure of speech intelligibility

Evidence

Subjective measures of intelligibility are often based on the use of lists of words that rhyme, differing only in their initial consonant. In a diagnostic rhyme test (DRT), listeners fill in the leading consonants on listening to the speech, and often the possible consonants will be indicated. In a modified rhyme test (MRT), each test consists of a pair-wise comparison of acoustically close initial consonants such as feel—veal, bowl—dole, fought—thought, pot—tot. — David M.
