摘　　要：提出一种基于PESQ算法的彩铃铃音质量评估系统,将通过网络传输后录制的音频文件与上传到彩铃平台上的对应的音频文件通过音质评价模块进行算法比较,得出客观评价,预知传输网络对该彩铃的影响到底有多大,从而得出该铃音是否适合作为彩铃铃音使用的结论。同时,通过对录制铃音的主观评价以及通过该系统对铃音的客观评价对比,最后确定该系统的主观和客观相关度达到95%以上,证明该系统可以以较高的准确率判断某音乐文件是否适合在某一地区作为彩铃铃音使用。In this paper we present a PESQ algorithm-based colour ring tone quality assessment system. The system conducts algorithm comparison on the audio file recorded after network transmission with the corresponding audio file uploaded to colour ring platform through audio quality assessment module to attain the objective evaluation, to foresee how much the influence of transmission network on the colour tings will be, and to derive the conclusion that whether the ring tone suites as the colour rings to use or not. What＇ s more, by comparing the subjective evaluation on ring tones recorded and the objective evaluation on ring tones via this system, eventually it confirms that the subjective and objective correlation in the system achieves 95% or higher. This testifies that this system is able to judge in high accuracy if a certain music file would be suitable for using as a colour ring tone in a certain region.
