The article describes an algorithm allowing intrusive speech transmission quality measurements in networks with low bit-rate coding schemes (600 ' 2400 bits/second) as used in satellite and military communications. The proposed algorithm is based on PESQ (ITU-T P.862) perceptual model, enhanced by input noise resistance capability. The new algorithm reflects also noise cancellation capabilities of modern audio coders. The correlation between Absolute Category Rating (ACR) Mean Opinion Score (MOS) listening test results and output of the developed algorithm achieves 0.89 without the knowledge of original noise-free speech sample.
