Diagnostic Rhyme Test (DRT)

     

Status Completely developed test.
Goal Diagnostic and comparative evaluation of the intelligibility of single initial consonants.
Languages Originally English [Voiers et al. (1975), Voiers (1983)], adapted (at least) to Dutch [Steeneken (1982)], and French [Peckels & Rossi (1973)].
Items Fixed set of 192 meaningful CVC-words. Examples: dune and tune. The Dutch version has 384 stimulus words from which different lists of 192 stimulus words can be composed.
Procedure Closed response  identification among two meaningful alternatives differing by a single phonetic feature in the initial consonant. Both alternatives are presented as a stimulus, so both dune and tune are presented with the response alternatives dune and tune. Six contrasts are represented, namely voicing , nasality , sustention , sibilation , graveness , and compactness . Each contrast is included 32 times in the test, combined with 8 different vowels.
Time With an interstimulus interval of 3 sec, about 15 min per synthesiser.
Analysis Intelligibility is expressed as the percentage correct initial consonants per contrast and for all initial consonants together. The percentages are corrected for chance.
