A method for generating a frequency warping function comprising preparing the training speech of a source and a target speaker; performing frame alignment on the training speech of the speakers; selecting aligned frames from the frame-aligned training speech of the speakers; extracting corresponding sets of formant parameters from the selected aligned frames; and generating a frequency warping function based on the corresponding sets of formant parameters. The step of selecting aligned frames preferably selects a pair of aligned frames in the middle of the same or similar frame-aligned phonemes with the same or similar contexts in the speech of the source speaker and target speaker. The step of generating a frequency warping function preferably uses the various pairs of corresponding formant parameters in the corresponding sets of formant parameters as key positions in a piecewise linear frequency warping function to generate the frequency warping function.

Generating a frequency warping function based on phoneme and context

A method and system that incorporates human recording with a TTS system to generate synthesized speech with high quality by searching over a database of pre-recorded utterances to select an utterance best matching text content to be synthesized into speech; dividing the best-matched utterance into a plurality of segments to generate remaining segments that are the same as corresponding parts of the text content and difference segments that are different from corresponding parts of the text content; synthesizing speech for the parts of the text content corresponding to the difference segments; and splicing the synthesized speech segments with the remaining segments of the best-matched utterance.
