A system and method for enabling a caller to obtain access to services via a telephone network by entering a spoken first character string having a plurality of digits. Preferably, the method includes the steps of prompting the caller to speak the first character string beginning with a first digit and ending with a last digit thereof, recognizing each spoken digit of the first character string using a speaker- independent voice recognition algorithm (49a, 69a), then following entry of the last digit of the first string, initially verifying the caller's identity using a voice verification algorithm (49b, 66b). After initial verification, the caller is again prompted to enter a second character string, which must also be recognized (49c, 66c) before access is effected.

Système et procédé permettant à un appelant d'avoir accès à des services via un réseau téléphonique en composant vocalement un premier numéro d'identification à plusieurs chiffres. Le procédé consiste de préférence à inviter l'appelant à épeler le premier numéro du premier au dernier chiffre, à reconnaître chacun des chiffres ainsi épelés, à l'aide d'un algorithme de reconnaissance de voix multilocuteur (49a, 69a), puis à vérifier l'identité de l'appelant à l'aide d'un algorithme de vérification de voix (49b, 66b). Après une première vérification, l'appelant est invité à composer un second numéro qui doit également être reconnu (49c, 66c) avant de lui donner accès aux services.
