A method for automatically and reproducibly rating the transmission quality of a speech transmission system, comprising the steps of: generating a test signal containing a predetermined recorded voice signal; transmitting the test signal by the speech transmission system from a transmitting end to a receiving end; extracting characteristic values from the received test signal; determining a differential pattern corresponding to the difference between the characteristic values and predetermined reference values; and feeding the differential pattern to a neural network that has been trained for classifying patterns according to a number of predetermined transmission quality classes.
