Abstract:
A template generation system for generating a duration template from a plurality of input words, comprising:a phonetic processor operable to segment each of said input words into input phonemes and group said input phonemes into constituent syllables, each of said constituent syllables having an associated syllable duration;a phoneme clustering module to cluster said input phonemes comprising a constituent syllable into input phoneme pairs and input single phonemes;a global static table containing a plurality of stored phonemes comprising stored phoneme pairs and stored single phonemes, each of said stored phonemes having associated static duration information;a normalization module to generate a normalized duration value for each of said constituent syllables, wherein said normalized duration value is generated by dividing the syllable duration by the combined static duration of the corresponding stored phonemes that comprise said constituent syllable;the duration template for storing the normalized duration value, said template being specified by text grouping feature, such that the normalized duration value for each constituent syllable having a specific grouping feature is contained in the associated duration template.
