บทคัดย่อ
The aim of this research is to the improve performance of the E-model, which is one of the most successful non-intrusive speech quality prediction models for voice communication over a packet based network. However, the E-model still has limitations. The calculation method of the E-model is restricted to a set of voice codecs from ITU-T. This paper proposes a method to estimate two codec-related parameters that used to calculate the E-model, which are called equipment impairment factor Ie and packet loss robustness factor Bpl of the non ITU-T codec. The process to estimate both parameters uses a curve fitting method to calculate Ie values from PESQ results under various levels of network packet loss. The set of Ie and Bpl of eight narrowband codecs (G.711, G.729, GSM, AMR, iLBC, Speex, Silk, and Opus) are presented. Statistical analysis was also performed for model validation. The results show that the E-model with our Ie and Bpl parameters achieved a good accuracy and a good correspondence with PESQ MOS among the eight codecs. ฉ Springer International Publishing Switzerland 2016.
