Expectations for discourse genre identification: a prosodic study

Speech can be divided into discourse genres based on the contextual environment it occurs in (e.g. political speech, sport commentary speech, etc.). The present study investigated whether listeners can distinguish between speech from different discourse genres on the basis of acoustic prosodic cues only 1 . In a perception experiment with delexicalized speech 70 listeners with varying experience in French (native speakers, nonnative speakers, and non-speakers) were asked to identify four different types of discourse genres (church service, political, journal, and sport commentary). Results revealed a fair identification ability with a significant increase in performance with increasing experience in French. Identification confusion was used to cluster discourse genres according to their perceptual similarity. The possible application of the results for the evaluation of speaking style speech synthesis will be discussed.
