| Abstract(in English) | POLQA that corresponds to wideband as an objective evaluation method of voice quality are being utilized. With this technology, it can quantitatively measure the quality of a VoIP application, captures the quality degradation events of the end-to-end, it is expected the application of network operation. On the other hand, when measuring the quality of the actual VoIP application using POLQA, it is necessary to such characteristics and volume setting evaluation terminal to properly grasp the influence of the measurement. Therefore, the approach to implementing the voice quality measurement for multiple VoIP applications on multiple terminals, the acoustic characteristics of the terminal is to consider the impact of POLQA, and selects an evaluation terminal suitable for using the POLQA voice quality evaluation. |
