Time window and short time power estimation for short time spectrum estimation unaffected by window position, apparent subharmonic components due to sidelobes of time window spectrum, nonparametric spectral envelope estimation, using speech spectral range information. We will present basic problems such as F0 estimation, periodicity measures, F0 likelihood, sound source pulse train frequency fluctuations, odd harmonic and even harmonic component ratios caused by sound source waveform duty ratio fluctuations, and present solutions and discuss solutions.}, title = {高精度音声信号解析に向けた試論}, year = {2024} }
