摘要: Measuring speech quality in Voice over Internet Protocol (VoIP) networks is an increasingly important application for legal, commercial and technical reasons. Any proposed solution measuring the should be applicable monitoring live-traffic non-intrusively. The E-Model by International Telecommunication Union-Telecommunication Standardisation Sector (ITU-T) achieves this, but it requires subjective tests to calibrate its parameters. In this paper a extend any new network conditions newly emerging codecs without need time-consuming, expensive, hard conduct tests. based on artificial neural model compared against check prediction accuracy.
