METHOD AND DEVICE FOR THE OBJECTIVE EVALUATION OF THE VOICE QUALITY OF A SPEECH SIGNAL TAKING INTO ACCOUNT THE CLASSIFICATION OF THE BACKGROUND NOISE CONTAINED IN THE SIGNAL

摘要

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.
