摘要：

Sinusoidal speech coders have been widely studied for low bit rate coding due to their capability of producing high quality speech. However, the estimation error of the sinusoidal model parameters, pitch in particular, would seriously degrade the speech quality. In this letter, we provide a Modified Pitch Detection Algorithm (MPDA). The experimental results show that the proposed method can provide a more accurate and smoother pitch tracking that that of IMBE, and the reconstructed speech sounds more continuous.
