"Person 00028 Authentification by Voice: A Need of Caution", Bonastre J.F., 00029 Bimbot F., Boe L.J., Campbell J.P., Douglas D.A., Magrin- 00030 chagnolleau I., Eurospeech 2003, Genova]. 00031 The conclusion of the paper of the paper is proposed bellow: 00032 [Currently, it is not possible to completely determine whether the 00033 similarity between two recordings is due to the speaker or to other 00034 factors, especially when: (a) the speaker does not cooperate, (b) there 00035 is no control over recording equipment, (c) recording conditions are not 00036 known, (d) one does not know whether the voice was disguised and, to a 00037 lesser extent, (e) the linguistic content of the message is not 00038 controlled. Caution and judgment must be exercised when applying speaker 00039 recognition techniques, whether human or automatic, to account for these 00040 uncontrolled factors. Under more constrained or calibrated situations, 00041 or as an aid for investigative purposes, judicious application of these 00042 techniques may be suitable, provided they are not considered as infallible. 00043 At the present time, there is no scientific process that enables one to 00044 uniquely characterize a person=92s voice or to identify with absolute 00045 certainty an individual from his or her voice.] 00046 Contact Jean-Francois Bonastre for more information about the licence or 00047 the use of ALIZE 00048 00049 Copyright (C) 2003-2010 00050 Laboratoire d'informatique d'Avignon [lia.univ-avignon.fr] 00051 ALIZE admin [alize@univ-avignon.fr] 00052 Jean-Francois Bonastre [jean-francois.bonastre@univ-avignon.fr] 00053 */ 00054 00055 #if !defined(ALIZE_MixtureFileReaderAmiral_h) 00056 #define ALIZE_MixtureFileReaderAmiral_h 00057 00058 #if defined(_WIN32) 00059 #if defined(ALIZE_EXPORTS) 00060 #define ALIZE_API __declspec(dllexport) 00061 #else 00062 #define ALIZE_API __declspec(dllimport) 00063 #endif 00064 #else 00065 #define ALIZE_API 00066 #endif 00067 00068 #include "MixtureFileReaderAbstract.h" 00069 00070 namespace alize 00071 { 00072 class DistribGD; 00073 class Config; 00074 00081 00082 class ALIZE_API MixtureFileReaderAmiral : public MixtureFileReaderAbstract 00083 { 00084 00085 public : 00086 00094 explicit MixtureFileReaderAmiral(const FileName& f, const Config& c, 00095 BigEndian be = BIGENDIAN_AUTO); 00096 00104 static MixtureFileReaderAmiral& create(const FileName& f, 00105 const Config& c, BigEndian be = BIGENDIAN_AUTO); 00106 00107 virtual ~MixtureFileReaderAmiral(); 00108 00115 virtual const Mixture& readMixture(); 00116 00123 virtual const MixtureGD& readMixtureGD(); 00124 00125 virtual String getClassName() const; 00126 00127 private : 00128 00129 unsigned long _vectSize; 00130 00132 00133 void readVersionGD2(); 00134 00136 00137 void readVersion2(); 00138 00140 00141 void readDistribGD(DistribGD&); 00142 00143 bool operator==(const MixtureFileReaderAmiral&) 00144 const; 00145 bool operator!=(const MixtureFileReaderAmiral&) 00146 const; 00147 const MixtureFileReaderAmiral& operator=( 00148 const MixtureFileReaderAmiral&); 00149 MixtureFileReaderAmiral( 00150 const MixtureFileReaderAmiral&); 00151 }; 00152 00153 } // end namespace alize 00154 00155 #endif // !defined(ALIZE_MixtureFileReaderAmiral_h) 00156
