Abstract
Ten subjects responded in a conventional multiple-choice format to two randomized lists of Diagnostic Rhyme Test (DRT) words in white noise at 3 dB signal-to-noise ratio. The DRT consists of 96 word-pairs whose initial phonemes differ by one feature: voice-unvoiced, nasal-oral, sustained-interrupted, sibilated-unsibilated, grave-acute, and compact-diffuse. List one consisted of DRT words counter-balanced for each feature and list two contained the contrasting feature. Three replicates were obtained for each subject for each list. Errant responses were analyzed for differences between distinctive features. Results are consistent with previous findings for equality of percent correct across DRT word lists. However, distinctive feature contrasts within word pairs were not equally difficult. For example, sibilated and unvoiced phonemes were significantly more difficult than their unsibilated or voiced counterpart, respectively. DRT word difficulty differences may \be attributed to at least three components: inherent energy differences between phonemes, temporal characteristics, and similarity to spectral content of the masking noise. © 2009 Acoustical Society of America.
