음성 파형코딩의 음원피치 변경에 관한 연구 - LPC와 주기반분법에 의한 피치변경법 -
On Altering the Pitch of Speech Signals in Waveform Coding -(Altering Method by the LPC and the Pitch Halving)-
초록
In area of the speech synthesis, the waveform coding with high quality are mainly used to the synthesis by analysis. However, it is difficult to applying the waveform coding to the synthesis by rule, because the parameters of this coding are not classified as either excitation parameters and vocal tract parameters. In this paper, we proposed a new pitch change method that can alter the pitch periods in the waveform coding. The proposed method expands the pitch period by the LPC synthesis method, and then the period is compressed by the waveform halving technique. Thus, it is possible that the waveform coding is carried out the synthesis by rule in speech processing.
