Abstract

A method for determining a speech quality measure of an output speech signal with respect to an input speech signal, wherein the input signal passes through a signal path of a data transmission system resulting in the output signal, includes the steps of pre-processing the output signal; determining at least one of an interruption rate of the pre-processed output signal and a measure for an intensity of musical tones present in the pre-processed output signal; and determining the speech quality measure from at least one of the interruption rate and the measure for the intensity of the musical tones.
