Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. GSM PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for GSM mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles, frequency hopping sequences and variable Additional White Gaussian Noise (AWGN).

PESQ measurements employ a level adaptation algorithm and are hence widely insensitive to absolute level. However, if the tests are performed via a speech codec, the driving level of the codec has an influence on the MOS result. Therefore careful alignment of the level is required. This application note provides an application program which runs on the Audio Analyzer R&S UPV or R&S UPV66 and can be used to calibrate signal levels for the PESQ measurement.
30-Jun-2011 | AN-No. 1GA50
This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively.
21-Feb-2014 | AN-No. 1MA204
Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. CDMA2000® PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for CDMA2000® mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles and variable Additional White Gaussian Noise (AWGN).
