Abstract: The voice quality of telephone calls is evaluated. A first connection is established between a computerized apparatus and a person acting as a first experimenter, and a second connection is established between the platform and a second experimenter. The first and second connections are interconnected by the computerized apparatus to establish a call between the two experimenters and enable them to converse, the apparatus being cut into the call in order to acquire data about the call. The experimenters' opinions are solicited concerning their perceptions of the quality level they observe during their conversation. The apparatus evaluates consistency of the data collected with the nominal experimental conditions and the nominal quality level associated with the current test. Then, a determination is made as to how the current test is to be carried out as a function of a test plan and of the result of the evaluation. The test plan is set up by specifying nominal conditions for the experiment and nominal quality levels for carrying out the tests, and in collecting data during the tests.

Abstract translation: 评估电话的语音质量。 在计算机化装置和作为第一实验者的人之间建立第一连接，并且在平台和第二实验者之间建立第二连接。 第一和第二连接通过计算机化设备相互连接，以在两个实验者之间建立一个呼叫，并且使得它们可以将设备切换成呼叫，以便获取有关呼叫的数据。 征求实验者的意见，了解他们对谈话期间观察到的质量水平的看法。 该设备评估所收集的数据与标称实验条件和与当前测试相关的名义质量水平的一致性。 然后，根据测试计划和评估结果确定如何进行当前测试。 测试计划是通过指定实验的名义条件和进行测试的名义质量水平以及在测试期间收集数据来设置的。
