听觉质量客观感知评估算法及其应用

摘要

ITU P.863是下一代语音质量测试技术，适用于固话、手机和IP网络。通过比较已知的参考信号和经过待测系统后的退化信号，得到MOS分。应用POLQA算法对手机的通话语音质量进行客观评估，分析影响手机通话性能的各种因素。%ITU-T P.863 is the next generation voice quality testing technique suitable for ifxed, mobile and IP-based networks. A known reference signal is compared with the degraded signal to obtain P.863 mean opinion score (MOS). The voice quality of handset with perceptual objective listening quality assessment (POLQA) algorithm was objectively assessed and the different factors affecting voice quality of handset were analyzed.
