Abstract:     A high performance voice transformation apparatus and method is provided in which voice input is transformed into a symbolic representation of phonemes in the voice input. The symbolic representation is used to retrieve output voice segments of a selected target speaker for use in outputting the voice input in a different voice. In addition, voice input characteristics are extracted from the voice input and are then applied to the output voice segments to thereby provide a more realistic human sounding voice output.

First Claim:
Show all 32 claims
What is claimed is:     1. A method of transforming a voice input into a voice output of a target speaker, comprising:
  • receiving the voice input;
  • extracting voice input characteristics from the voice input;
  • identifying voice input segments in the voice input;
  • identifying voice output segments of the target speaker corresponding to the voice input segments;
  • applying the voice input characteristics to the voice output segments of the target speaker to obtain output segments;
  • outputting the output segments;
  • identifying portions of the voice input that cannot be identified as voice input segments; and
  • outputting the portions of the voice input that cannot be identified as voice input segments;
  • wherein outputting the portions of the voice input that cannot be identified as voice input segments includes identifying target speaker output voice characteristics; and
  • applying the target speaker output voice characteristics to the portions of the voice input that cannot be identified as voice input segments.
