| Abstract(in English) | For quality assessment of Voice over IP (VoIP), subjective methods have been used. Nowadays, objective methods are being developed and focused on because they can assess the quality or speech more inexpensively than subjective methods. In this report, we evaluated the applicability of PSQM+, one of the objective methods, to speech deteriorated by background traffic on our VoIP network. First, we show that PSQM+ measurement results for samples of the same quality vary and it is impossible to estimate the quality of speech. Only the average of PSQM+ results can estimate the average quality of speech. Next, we show the quality of speech under the same network condition also varies and by using PSQM+, we can judge the quality of VoIP on the network to be always good, indeterminable, or always bad. |
