Abstract (en)
[origin: WO2010119216A1] The invention relates to a method and device for the objective evaluation of the voice quality of a speech signal, the device including: a module (11) for extracting a background noise signal, referred to as a noise signal, from the speech signal (SIG); a module (13) for calculating the audio parameters of the noise signal; a module (15) for classifying the background noise contained in the noise signal on the basis of the calculated audio parameters, according to a predefined set of background noise classes (CL); a module (17) for evaluating the voice quality of the speech signal on the basis of at least the resulting classification relative to the background noise in the speech signal.
