Codec-dependent unit selection for mobile devices
First Claim
1. A method of extracting a subset of speech units from a larger set of speech units for use by a codec in combination with a speech synthesizer in synthesizing speech, the method comprising:
- from the larger set of speech units, selecting members of the subset of speech units based in part on a cost measure associated with using the codec; and
storing the selected subset of speech units on a speech-enabled device.

Abstract
A method of extracting a subset of speech units from a larger set of speech units for use by a speech synthesizer in synthesizing speech, wherein the speech units are stored in a compressed encoded representation that was generated by a codec, the method comprising: selecting members of the subset of speech units based on an overall cost associated with using the speech synthesizer to synthesize a test set of speech, wherein the overall cost includes at least one error introduced by using the codec to decode the stored representations of the speech units; and storing the selected subset of speech units on a speech-enabled device.
