<p>A prosody modification system and methodology calculates synchronization marks in an original, quasi-periodic signal to a finer precision than the sampling rate of the original signal (200). Synthetic synchronization marks are generated according to the desired prosody modification also to a finer precision than the sampling rate of the original signal (202). Waveforms are extracted from the original signal (204) and are fine-shifted to the exact location on the synthetic time axis (206) by a resampling technique (208). The fine-shifted waveforms are windowed by an asymmetric filtering window (210), overlapped, and summed together to produce a synthetic signal (212).</p> |
