Improving Quality and Prosody of CHATR
Synthesis Speech
Based on PSOLA
Abstract:We address two issues in this paper : (1) How to derive a perceptual discontinuity function to determine the perceptually significant amount of discontinuity
between two candidate units, while (2) taking into account the constraints of possible prosodic modification (pitch/duration scaling using signal processing). Both
the techniques are tested with the unit selection and synthesis modules and the
changes in voice quality and prosody are evaluated.
