Abstract
The present invention provides a method for synthesizing speech by modifying the prosody of individual components of a training speech signal and then combining the modified speech segments. The method includes selecting an input speech segment and identifying an output prosody. The prosody of the input speech segment is then changed by independently changing the prosody of a voiced component and an unvoiced component of the input speech signal. These changes produce an output voiced component and an output unvoiced component that are combined to produce an output speech segment. The output speech segment is then combined with other speech segments to form synthesized speech.
