        authentication in a forensic context.

        The "Person  Authentification by Voice: A Need of Caution" paper 

        proposes a good overview of this point (cf. "Person  

        Authentification by Voice: A Need of Caution", Bonastre J.F., 

        Bimbot F., Boe L.J., Campbell J.P., Douglas D.A., Magrin-

        chagnolleau I., Eurospeech 2003, Genova].

        The conclusion of the paper of the paper is proposed bellow:

        [Currently, it is not possible to completely determine whether the 

        similarity between two recordings is due to the speaker or to other 

        factors, especially when: (a) the speaker does not cooperate, (b) there 

        is no control over recording equipment, (c) recording conditions are not 

        known, (d) one does not know whether the voice was disguised and, to a 

        lesser extent, (e) the linguistic content of the message is not 

        controlled. Caution and judgment must be exercised when applying speaker 

        recognition techniques, whether human or automatic, to account for these 

        uncontrolled factors. Under more constrained or calibrated situations, 

        or as an aid for investigative purposes, judicious application of these 

        techniques may be suitable, provided they are not considered as infallible.

        At the present time, there is no scientific process that enables one to 

        uniquely characterize a person=92s voice or to identify with absolute 

        certainty an individual from his or her voice.]
