摘要 水声语音通信质量的实时测量是保障通信质量的重要环节,利用实时测量结果可及时调整语音业务的调制参数,提高链路的自适应能力。本文提出了一种基于参数表示的语音通信质量实时估测模型,该模型提取语音3个特征参数,即:Mel频率倒谱系数(Mel-frequency cepstum coefficient,MFCC)、线性预测倒谱系数(Linear predictive cepstrum coefficient,LPCC)及加权对数谱(Log spectral deviation,LSD),构建3种特征参数的权重谱失真测度。利用失真测度与接收语音质量(Perceptual evaluation of speech quality-mean opinion score,PESQ-MOS)之间的映射关系,建立语音质量估测模型。引入动态MFCC(Dynamic Mel-frequency cepstrtum coefficient,DMFCC)的谱失真测度作为质量估测模型的调节因子,使估测系统具有更好的适应性。实验及海测结果显示,利用本模型估测的语音MOS值与人主观感受误差较小,具有一定的实用性。 The real‐time measurement of quality of the underwater acoustic voice communication is crucial to communication quality .Real‐time measurements can help to adjust voice modulation parameters time‐ly and improve the adaptive ability of link .An objective assessment model for voice quality is proposed based on parameter extraction ,based on the underwater acoustic channel characteristics .Three feature parameters of voice are extracted :Mel‐frequency cepstrum coefficient (MFCC) ,linear predictive ceps‐trum coefficient(LPCC ) and log spectral deviation(LSD) .The three parameters form the weight spec‐tral distortion evaluation .the mapping relationship of distortion evaluation and receive voice quality of perceptual evaluation of speech quality ‐mean opinion score (PESQ‐MOS) is used to conduct quantiza‐tion .Dynamic Mel‐frequency cepstrum coefficient (DMFCC) spectral distortion evaluation is also intro‐duced as regulatory factor ,which improves the adapt‐ability .The results of simulation and sea test show that the measured MOS via the assessment model is close to PESQ‐MOS ,which indicated the model has practical value .
