| Abstract(in English) | As broadband and high-speed IP networks spread, IP-telephony services have become a popular speech communication application over IP networks. Recently, the speech quality of IP-telephony services has become close to that of conventional PSTN services. To provide better speech quality to users, wideband speech communication is investigated. To ensure desirable quality, we should design the quality before services start and manage it while they are being provided. To design and manage the quality appropriately, an effective means for estimating conversational quality is indispensable. We propose a model for estimating the conversational quality of wideband speech communication services from physical characteristics of terminals and networks. Based on the subjective conversational quality evaluation experiments, it is shown that the proposed model can accurately estimate the subjective quality for wideband speech. |
