摘　　要：为了解决目前4G通信网络中语音质量评价问题,该研究基于PESQ算法,设计开发了语音质量评价系统。该系统主要由语音采样和语音质量评价两个部分组成,语音采样部分由具有录音功能的手机进行样本采集,语音质量评价系统则调用PESQ算法对语音样本文件给出MOS平均意见分。该系统个性化和模块化的设计特点保证它能对不同的4G网络类型进行语音质量评价。系统运行实践证明该系统能有效对4G网络通信语音质量做出客观评价,因而具有一定推广价值。With the popularization of 4G communication network in modern society,some new problems in the application process have occurred naturally. A speech quality evaluation system designed and developed on the basis of PESQ algorithm to solve the problem in evaluation of speech quality during the process of communication. The system is composed of two parts in which the first part is devoted to speech sampling and the second part is used to evaluate the speech quality. The speech sampling is conducted by the mobile phones which have the record function. The speech quality evaluation system gives a MOS average mark based on PESQ algorithm. The characteristics of individualization and modular design guaranteed the successful application of this system to evaluate different kinds of 4G communication networks. The operation practice of this system has proved this system can objectively evaluate speech quality of 4G network communication.
