Modelling Hesitation for Synthesis of Spontaneous Speech

  title={Modelling Hesitation for Synthesis of Spontaneous Speech},
  author={Rolf Carlson and Kjell Gustafson and Eva Strangert},
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… CONTINUE READING
