Abstract:
Systems, methods, and computer-readable storage devices to improve the quality of synthetic speech generation. A system selects speech units from a speech unit database, the speech units corresponding to text to be converted to speech. The system identifies a desired prosodic curve of speech produced from the selected speech units, and also identifies an actual prosodic curve of the speech units. The selected speech units are modified such that a new prosodic curve of the modified speech units matches the desired prosodic curve. The system stores the modified speech units into the speech unit database for use in generating future speech, thereby increasing the prosodic coverage of the database with the expectation of improving the output quality.

Claim (Index 9):
A system comprising:\n a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising: determining a cost of modifying residual coefficients, the residual coefficients generated by decomposing speech units from a speech unit database, to yield a determination; modifying, via a pitch synchronous overlap and add algorithm, the residual coefficients, to yield modified residual coefficients based on the determination; and generating speech based on new speech units that are produced based on the modified residual coefficients.
