Sixth International Conference on Spoken Language Processing
In this paper, we propose a novel unit concatenation and synthesis method using ABS/OLA sinusoidal model. Phase succession is used in the unit synthesis assuming that the pitch onset time of the first frame in a given unit is the frame center. In the unit concatenation, the phase succession and interpolation of the sinusoid amplitudes via several frames around the concatenation point is utilized. As a result of applying this method to the Text-to- Speech(TTS) system, we got speech samples which were more intelligible and natural than those produced by conventional method.
