Non-Intrusive voice Quality Analyzer
NIQA
-
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).
