Abstract:
1. A method for evaluating the voice quality of telephone calls, comprising: (a) setting up a test plan specifying nominal experimental conditions and nominal quality levels for carrying out tests and collecting data during the tests relating to the quality of voice calls transmitted over a mobile telecommunications network; (b) performing a current test by establishing a first connection between a platform and a first experimenter and a second connection between the platform and a second experimenter; (c) interconnecting the first and second connections by means on the platform to establish a call between the first and second experimenters for enabling them to converse, the platform being cut into the call in order to acquire data about the call; (d) acquiring current experimental conditions by collecting data including opinions of the first and second experimenters concerning their perceptions of the quality level they note during their conversation; (e) evaluating consistency between nominal experimental conditions and the nominal quality level associated with the current test; and (f) determining, as a function of the test plan and of the result of the evaluation, how performance of the current test is to be continued.
