DiSS-LPSS Joint Workshop 2010
The 5th Workshop on Disfluency in Spontaneous Speech
This paper investigates the prosodic patterns of non-lexical response tokens in a Swedish call-in radio show. The feedback of a professional speaker was investigated to give insight in how to build a simulated active listener that could encourage its users to continue talking. Possible domains for such systems include customer care and second language learning. The prosodic analysis of the non-lexical response tokens showed that the engagement level decreases over time. Prosodic cues to this include change in syllabicity, pitch slope and loudness. We have also investigated prosodic alignment, to see to what extent the active listener mimic the prosody of the callers in his non-lexical response tokens.
