| Wideband extension to Recommendation P.862 for the assessment of wideband telephone networks and speech codecs |
 |
ITU-T Recommendation P.862.2 describes a simple extension to the perceptual evaluation of listening speech quality (PESQ) algorithm defined in ITU-T Recommendation P.862. It allows ITU-T Recommendation P.862 to be applied to the evaluation of conditions, such as speech codecs, where the listener uses wideband headphones. (In contrast, ITU-T Recommendation P.862 assumes a standard IRS-type narrow-band telephone handset which attenuates strongly below 300 Hz and above 3100 Hz.).
This Recommendation is mainly intended for use with wideband audio systems (50-7000 Hz), although it may also be applied to systems with a narrower bandwidth. |
