multimedia perception assessment center (MPAC)

Multimedia Perception Assessment Center (MPAC) is a speech quality assessment procedure developed by Lucent, similar to Perceptual Evaluation of Speech Quality

(PESQ). The MPAC procedure evaluates speech samples at various packet loss rates. In addition, it also deals with the evaluation of speech quality in the case of loss of several consecutive data packets

, data bursts. Since these disturbances cannot be compensated on the receiving side, they have a direct impact on the speech quality. In the MPAC evaluation, the Mean Opinion Score (MOS) and the PESQ value are averaged before calculation.
