00003 toolkit for speaker recognition. ALIZE toolkit is required to use LIA_RAL.

00005 LIA_RAL project is a development project was initiated by the computer
00006 science laboratory of Avignon / France (Laboratoire Informatique d'Avignon -
00007 LIA) [http://lia.univ-avignon.fr <http://lia.univ-avignon.fr/>]. Then it
00008 was supported by two national projects of the French Research Ministry:
00009         - TECHNOLANGUE program [http://www.technolangue.net]
00010         - MISTRAL program [http://mistral.univ-avignon.fr]

00026 The LIA team as well as the LIA_RAL project team wants to highlight the
00027 limits of voice authentication in a forensic context.
00028 The "Person Authentification by Voice: A Need of Caution" paper
00029 proposes a good overview of this point (cf. "Person
00030 Authentification by Voice: A Need of Caution", Bonastre J.F.,
00031 Bimbot F., Boe L.J., Campbell J.P., Douglas D.A., Magrin-
00032 chagnolleau I., Eurospeech 2003, Genova].
00033 The conclusion of the paper of the paper is proposed bellow:
00034 [Currently, it is not possible to completely determine whether the
00035 similarity between two recordings is due to the speaker or to other
00036 factors, especially when: (a) the speaker does not cooperate, (b) there
00037 is no control over recording equipment, (c) recording conditions are not
00038 known, (d) one does not know whether the voice was disguised and, to a
00039 lesser extent, (e) the linguistic content of the message is not
00040 controlled. Caution and judgment must be exercised when applying speaker
00041 recognition techniques, whether human or automatic, to account for these
00042 uncontrolled factors. Under more constrained or calibrated situations,
00043 or as an aid for investigative purposes, judicious application of these
00044 techniques may be suitable, provided they are not considered as infallible.
00045 At the present time, there is no scientific process that enables one to
00046 uniquely characterize a persones voice or to identify with absolute
00047 certainty an individual from his or her voice.]
