Modelling hesitation for synthesis of spontaneous speech
2006 (English)In: Proceedings of Speech Prosody 2006, Dresden, Germany, 2006, 69-72 p.Conference paper (Refereed)
The current work deals with the modelling of one type of disfluency, hesitations. A perceptual experiment using speech synthesis was designed to evaluate two duration features found to be correlates to hesitation, pause duration and final lengthening. A variation of F0 slope before the hesitation was also included. The most important finding is that it is the total duration increase that is the valid cue rather than the contribution by either factor. In addition, our findings lead us to assume an interaction with syntax. The absence of strong effects of the induced F0 variation was unexpected and we consider several possible explanations for this result.
