required;Moderate effort required;Considerable effort required ;No meaning understood with reasonable effort;Listening Effort Scale“ 在国际标准中,统一使用 MOS(MeanOpinionScore )方法来评价语音压缩后的质量。在 MOS 方法中,电话语音质量的标准定为 4 分。这就是说,如果一种算法将语音压缩后,MOS 值能达到 4 分,就说明其语音质量和电话质量等同,用户无法分辨出其中的区别。G.723.1 压缩算法的 MOS 评测值是:3.98(Source:DSPGroupInc., ) ,即非常接近电话质量。窄带环境下选用 G.723.1 语音压缩标准: a.压缩率高:G.723.1 算法将语音压缩到6.3Kbps,在同类压缩算法中压缩率是最高的。 ;b. 语音质量好:经 G.723.1 算法压缩后的语音质量 MOS 值能达到 3.98 分,即使说对于一般没有受过专门训练的耳朵,已经无法区分语音是否经过压缩。这样的语音质量完全满足了网络视频会议系统的需求。c.宽带环境下选用 Cep 语音压缩标准,以保证声音质量更加清晰丰满,满足宽带用户对质量的高要求。MOU minutes
