摘要:
本文的目的是研究最新客观语音质量评估算法的表现。在通信系统中，语音的质量对于评估系统的表现是一个主要的因素。为了达到评估语音质量的目的，开发有效的语音质量评估算法是必须的。感知的语音质量客观评估算法是最有用和最便捷的方法。在这篇论文里，我们将要讨论评估通信系统和网路中的语音质量的最新的ITU标准PESQ (语音质量的感知评估)和POLQA (感知客观语音质量评估)算法。POLQA是一个技术升级，它能够覆盖最新的语音编码和网络传输技术，对于3G，4G/LTE和VoIP网络有了更高的准确度。我们分析了POLQA的表现，并且将POLQA和PESQ作了对比。从实验数据的结论来看，我们得出了如下结论：POLQA相较于PESQ有更好的表现，并且即将替代PESQ。The aim of this paper is to investigate the performance of the latest objective speech quality assessment algorithm. In the communication system, the quality of speech is an important factor to evaluate the performance of the system. In order to achieve speech quality assessment, it is necessary to develop effective speech quality assessment method. The perceptive speech quality objective assessment algorithm is the most useful and convenient method. In this paper we will discuss the PESQ (Perceptual Evaluation of Speech Quality) and POLQA (Perceptual objective listening quality assessment) algorithm, which are the latest ITU standard for evaluating speech quality for communication systems and networks. POLQA is a technology upgrade covering the latest speech coding and network transport technology, with higher accuracy for 3G, 4G/LTE and VoIP networks. We analyze the performance of POLQA, and make a comparison between POLQA and PESQ. From the result of the experiment data, we can conclude that the POLQA performance is better than the PESQ, and the POLQA will replace the PESQ in the future.
