Abstract :
The topic addressed by this paper is related to a very specific operation in prosodic modifications, the calculus of the virtual time instants, for speech models based on a pitch synchronous analysis/synthesis. We propose and describe in detail a straightforward algorithm for the calculus of these moments. Also we present the results we obtained with the proposed algorithm, which show that the pitch synchronism is kept, without altering the quality of the time/pitch scaled signal.
