摘要：
Based on the Mixed Excitation Linear Prediction (MELP) model, this paper presents a vocoder to obtain high-quality synthetic speech at 800 bps with 25% redundancy for channel coding. The vocoder parameters are designed and an unequal error protection method is proposed to improve the robustness over random error channel. Several channel coding schemes are compared and the optimal one is then selected. Test results show that the proposed speech coding algorithm could provide satisfactory speech quality and also have strong robustness for channel error.
