This paper describes a high quality Japanese text to speech (TTS) system, PureTalk. This system is similar to the conventional diphone-based TTS using PSOLA except that PureTalk employs the following novel tech- niques which enable to produce more intelligible and nat- ural-sounding speech: 1) two-stage duration modeling based on a linear regression technique, 2) F0 contour modeling using polynomial segment models, 3) sophisti- cated waveform unit selection, and 4) ecient waveform compression designed for TTS system. The result of the subjective hearing test shows that PureTalk achieves high quality under practical computation and memory requirement.
