This paper presents a speech analysis and synthesis method that can precisely synthesize speech waveforms for high quality statistical parametric speech synthesis. The proposed method is based on pitch-synchronous analysis. A power spectrum, aperiodicity measure, pitch, and phase spectrum of each analysis frame is represented by a mel LSP (MLSP), band aperiodicity (BAP), log fundamental frequency (LF0) and new band group delay with compensation parameter (BGRDC), respectively. The BGRDC consists of a band group delay parameter which represents a mean time of each frequency band and a compensation parameter which recovers a phase spectrum at the boundary of the band. We also propose a band group delay vocoder that enables fast generation of speech waveforms by using time domain excitation generation and a vocal tract filter. We show that the proposed method can precisely generate speech waveforms by objective and subjective evaluations. |
