Abstract:
This document is devoted to and analysis of the intelligibility of semantically anomalous sentences presented in four acoustically different conditions: (1) natural speech, no noise; (2) vocoded speech, no noise; (3) vocoded speech, noise added to the pitch track; (4) vocoded speech, noise to the spectrum. One objective was to analyze the specific types of errors in each conditions. The other objective was to compare results of this analysis with results obtained from the Diagnostic Rhyme Test (DRT). Results revealed that intelligibility was quite good in conditions (1) and (2), relatively poor in (3), and quite poor in (4) -- results consistent with DRT data. Further, about 60% of all errors were phonemic, while 40% were syntactic and semantic. We conclude that information in the spectrum is more critical than information in the pitch track, that most errors affect the phonological component when intelligibility is poor and context is uncertain, and that the DRT is an appropriate though perhaps insufficient test of speech intelligibility. Additional keywords: Speech perception. (Author)
