1. Festival extracts utterance information from an input text.
2. The uttrance information is saved as "utt.feats" on working directory.
3. Festival calls htsvoice.pl.
4. In htsvoice.pl, the utterance information is converted to corresponding context-dependent label sequence.
5. hts_engine is called from htsvoice.pl.
6. A waveform is synthesized and saved in raw audio format.
7. RIFF header is appended to raw audio by sox.
8. Resultant wav file is loaded by festival,

Please see hts.scm included in our hts voices.

In the next festival release (2.0?), hts_engine will be integrated as a function of the festival.
