We have presented models for objective prediction of the voice quality for IP networks and also monitor the quality control of VoIP networks. We studied the methods to find the quality of audio. The study has analysed the quality of VoIP connection and indicate during quality decrease. This exercise provided the chance of solving the issues in VoIP network before users are affected by VoIP specific connection problems (echo, noise or breaks in the conversation). The signal waveform envelope distortion is reviewed; practical questions of its numerical implementation are discussed. We supported the study with many illustrations.}, }
