【摘要】 文章介绍了一种以计算线性预测编码倒谱系数距离(LPC—CD)作为对受扰语音信号质量评价的客观测度准则。针对不同通信条件,不同干扰样式下的受扰语音信号进行客观测量,并拟合出用客观测量值来预测主观的二次拟合曲线,达到了较高的主客观一致性。更多还原

【Abstract】 By computing Linear Predictor Code Cep-strum - Distance, this thesis introduce a advanced method to test the speech signal quality objectively and in the end give curves to predict the Mean Opinion Score objectively in different condition and different jamming pattern. This method can get high coherence between subjective and objective opinion of signal quality.更多还原
