Development and evaluation of a Dutch diagnostic rhyme test for assessing the intelligibility of speech communication channels

A subjective intelligibility measuring method, based on a two-alternative forced-choice test, was developed for the Dutch language. This test is comparable with the American Diagnostic Rhyme Test as developed by Voiers. The fundamentals and phonetic background of the Dutch implementation are given. The reproducibility and the relation to other intelligibility measures were studied for 40 different reference channels. The results show that the subjects need not be trained and that the measuring results are comparable with results obtained with phonetically balanced word lists.
