An automatic pitch-marking method using wavelet transform

Masaharu Sakamoto, Takashi Saitoh

This paper describes a new automatic pitch-marking method using wavelet transform. This method detects discontinuity in the speech waveform which occurs at the glottal closure instant (GCI). A time domain prosodic modification technique requires an appropriate determination of the synthesis pitch-marks. We evaluated the performance of the newly developed pitchmarking method by using our internal speech databases with an electroglottograph signal. We achieved 96 percent detection accuracy on the performance evaluation. We confirmed that the proposed pitch-marking method is suitable for waveform concatenation-based synthesis through a listening test using pitch modified speech.
