Voice Source Modeling Using Harmonic Compensated LF Model

LF 모델에 고조파 성분을 보상한 음원 모델링

In speech synthesis, LF model is widely used for excitation signal for voice source coding system. But LF model does not represent the harmonic frequencies of excitation signal. We propose an effective method which use sinusoidal functions for representing the harmonics of voice source signal. The proposed method could achieve more exact voice source waveform and better synthesized speech quality than LF model.
