Abstract: front page image
(EN) 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.
(FR) Procédé et dispositif d'évaluation objective de la qualité vocale d'un signal de parole, le dispositif comprenant : - un module (11 ) d'extraction à partir du signal de parole (SIG) d'un signal de bruit de fond, dit signal de bruit; - un module (13) de calcul de paramètres audio du signal de bruit; - un module (15) de classification du bruit de fond contenu dans le signal de bruit, en fonction des paramètres audio calculés, selon un ensemble prédéfini de classes de bruits de fond (CL); - un module (17) d'évaluation de la qualité vocale du signal de parole, en fonction d'au moins la classification obtenue relative au bruit de fond présent dans le signal de parole.
