NON-INTRUSIVE SPEECH-QUALITY ASSESSMENT

阅读:656发布:2021-08-25

专利汇可以提供NON-INTRUSIVE SPEECH-QUALITY ASSESSMENT专利检索,专利查询,专利分析的服务。并且This invention relates to non-intrusive speech-quality assessment using vocal-tract models, in particular for testing telecommunications systems and equipment. This process requires the reduction of the speech stream under assessment into a set of parameters that are sensitive to the types of distortion to be assessed. Once parameterised, the data is used to generate a set of physiologically-based rules for error identification, using a parametric modelling of the shape of the vocal tract itself, by comparison between derived parameters and the output of models of physiologically realistic forms for the vocal tract, and the application of physical constraints on how these can change over time.,下面是NON-INTRUSIVE SPEECH-QUALITY ASSESSMENT专利的具体信息内容。
