Abstract
The paper deals with a non-intrusive approach to the speech quality assessment and examines an
impact of network jitter on effective equipment impairment factor in E-model. In order to improve currently
used computational E-model (ITU-T G.107), we proposed an optimization based on numerous measurements
and experiments with an objective intrusive method PESQ (Perceptual Evaluation of Speech Quality) under
varying delay, packet loss, jitter and play-out buffer. Comparing achieved results in experiments and the
computed values in E-model, we proposed modification which improves estimated MOS of E-model.
