Abstract:
In this paper, we compare two methods for prosody (duration and pitch) modification. These are prosody modification using instants of Significant Excitation and Mel-Cepstral vocoder. We show that duration modifications are better using Mel- Cepstral vocoder for higher modification factor while pitch modifications are better using instants of Significant Excitations. In the end we show that Mel-Cepstral vocoder provides flexibility for non-uniform prosody manipulation
