| Abstract(in English) | The artificial voice conforming to ITU-T Recommendation P.50 has been only verified using LPC Cepstrum Distance measure as speech quality scale for conventional waveform coding. This paper verifies the availability of the P.50 for modern CELP-type coding distortion widely used in mobile telephone system and IP-based telephone system, and discontinuous distortion such as packet loss and transmission error. The speech quality scale used in the verification test is PESO (Perceptual Evaluation of Speech Quality) newly standardized as Recommendation P.862. It was concluded that the artificial voice standardized as Rec. P.50 is available for objective quality evaluation of CELP-type coding as well as waveformcoding. |
