METHOD, DEVICE, AND PROGRAM FOR SPEECH ANALYSIS AND SYNTHESIS, AND RECORDING MEDIUM WITH SAME PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a speech analyzing and synthesizing method of extracting a sine wave component of an input speech and synthesizing a speech by using the extracted sine wave component while the quality of an output speech is improved. SOLUTION: The method has a procedure of estimating a momentary frequency by precisely decomposing an input speech signal into a sine wave component by extracting a harmonic component of the input speech signal as a momentary frequency attractor, a procedure of estimating a spectrum envelope of the input speech signal, and a procedure of synthesizing a speech by driving a sine wave with the estimated momentary frequency and the spectrum envelope of the speech signal.
