Abstract:
A method for synthesizing speech from input speech segments, at least one input speech segment having an original prosody and having a mixed portion with a voiced component and an unvoiced component, the method comprising:selecting an input speech segment;identifying an output prosody;changing the original prosody of the selected input speech segment to produce an output speech segment so that the prosody of the output speech segment matches the output prosody through steps comprising:changing the prosody of a voiced component of a mixed portion of the input speech segment to produce an output voiced component;changing the prosody of an unvoiced component of the mixed portion of the input speech segment to produce an output unvoiced component by generating a frequency-domain representation of the unvoiced component directly from the input speech segment and changing the frequency-domain representation to change the prosody of the unvoiced component;combining the output voiced component and the output unvoiced component to produce an output mixed portion for an output speech segment; andcombining the output speech segment with other speech segments to form synthesized speech.
