Zusammenfassung:	The present invention relates to a method for identifying at least one person on board a motor vehicle by voice analysis, the method comprising: - a step of acquiring and digitising a voice signal (Ea) of a user in order to obtain a digitised signal, - a step of processing the digitised signal (Eb), - a step of comparing (Ec) the digitised signal with a voice profile, - a step of establishing a correspondence rate (Ed), - a step of comparing the correspondence rate (Ef) with a predefined threshold, - an identification step (Ef) in which, if the correspondence rate is greater than or equal to the predefined threshold, the user is identified, the voice profile selected in the comparison step (Ec) being a contextual voice profile comprising the vocal characteristics of a sound signal comprising a reference voice signal and noises present in the vehicle.
