抄録

<p>This study has investigated a technique that replicates waveform fluctuations of speech signals by combining partials of limited Q, a parameter defined as the ratio dividing a center frequency of a resonance by its bandwidth. This paper shows that the proposed technique may potentially generate amplitude and period fluctuations of 1/f-like frequency characteristics, which are considered to be one of the indices reflecting the naturalness of human speech.</p>
