Title:
SPEECH SYNTHESIS SYSTEM, SPEECH SYNTHESIS PROGRAM, AND SPEECH SYNTHESIS METHOD
Document Type and Number:
WIPO Patent Application WO/2018/159402
Kind Code:
A1
Abstract:
This speech synthesis system includes: a first extraction unit that extracts, at every unit interval, a fundamental frequency of a speech waveform corresponding to a known text; a second extraction unit that extracts, at every unit interval, a periodic component and a non-periodic component from the speech waveform; a third extraction unit that extracts spectral envelopes of the extracted periodic component and non-periodic component; a generation unit that generates a context label on the basis of context information of the known text; and a learning unit that performs learning by associating an acoustic feature amount including the fundamental frequency, the spectral envelope of the periodic component, and the spectral envelope of the non-periodic component with the corresponding context label, thereby constructing a statistical model.
