摘要 为了研究POLQA算法在Vo LTE语音质量评估中的表现,首先介绍了POLQA算法的原理,然后通过Vo LTE语音实测法,对比了POLQA算法和PESQ算法的评分差异以及影响POLQA评分结果的相关因素。测试结果表明,POLQA评分结果优于PESQ但会受到语料、网络制式、话音回落2G等情况的影响。 To investigate the performance of POLQA algorithm in Vo LTE speech quality test, the paper fi rst introduced the principle of POLQA algorithm, then through actual Vo LTE speech test compared the scoring differences POLQA and PESQ as well as infl uential factors. The results showed that the POLQA score is better than that of PESQ and was infl uenced by speech material, network type, return to 2G, etc.
