Abstract:
1. A method comprising: receiving input text; when candidate phonemes for synthesizing speech based on the input text are available from a top N triphone units, applying, using a processor, a cost process to select a set of phonemes from the candidate phonemes, wherein the top N triphone units are determined, prior to receiving the input text, from a database comprising a plurality of triphone units, and wherein the top N triphone units comprise those triphone units having lowest target costs when each triphone unit is individually combined into a 5-phoneme combination; when no candidate phonemes are available in the top N triphone units, applying a single phoneme approach to select single phonemes for synthesis; and synthesizing speech using at least one of the set of phonemes from the candidate phonemes and the single phonemes, which, when used, are used independent of a triphone structure.
