ITU-T P.505 AMD 1-2012 语音质量测量结果的单视图可视化.修改件1:新附录II.质量饼状图用在线工具.12号研究组

This tool provides a novel methodology for quality representation, which is both easy to use and easy to understand for non-experts and which can serve as a basis for commercial decisions on a management or marketing level. It offers: quick and easy recognition of expected speech quality problems for selected parameters(limit value violation); assessment of strengths and weaknesses of signal processing implemented in a terminal or other telecommunication equipment, including end-to-end considerations (quality statement); easy comparison of different equipment or connections based on the corresponding representations; easy extension of the representation by new parameters that will be relevant to quality in the future.
