| 摘 要： | 利用线谱对参数建立了针对紫外光通信的语音参数补偿模型,采用基于LSF参数奇偶采样插值方法和丢失能量线性补偿法,对样本的丢包补偿前后相关系数和音质进行了对比.仿真结果表明,前后帧的中值补偿替代丢失帧的参数效果最好;该方法简单有效,对语音质量有较大改善.

| Abstract: | A speech parameter compensation model aiming at UV communication was established by using LSP parameter.The "mode matching" and "pitch check" were applied to the analysis and comparison of all kinds of packets loss compensation methods based on "LSF Parameter Recovering".The simulation result shows that LSF parameter can be used to improve the speech quality. |
