The method and the device for effecting objective quality measures on speech transmission apparatuses allow the reproduction of the characteristics of the linear part of a system under test, utilizing only the system input and output signals; these characteristics are used to generate a reference signal, obtained from the input signal to the system, with which to compare the output signal of the system, and then to obtain an objective quality measure. …<??>This allows elimination of the effects of the linear characteristics, which affect the objective measure without influencing the quality of system performance. |
