Abstract
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.
Claims
1. A method for enabling a caller to obtain access to one or more services via a telephone network by speaking first and second character strings each having a plurality of characters, comprising the steps of:
(a) prompting the caller to speak the first character string beginning with a first character and ending with a last character thereof;
(b) generating speech feature data for each spoken character of the first character string; (c) applying the speech feature data and voice recognition feature transformation to generate a first set of perameters for each spoken character of the first character string, the first set of parameters for use in a voice recognition system;
(d) applying the speech feature data and voice verification feature transformation data to a voice verification feature transformation to generate a second set of parameters for each spoken character of the first character string, the second set of parameters for use in a voice verification system;
(e) recognizing the first character string using the first set of parameters;
(f) initially verifying the caller's identify using the second set of parameters generated for the first character string; and (g) repeating steps (a)-(c) and (e) using the second character string instead of the first character string to confirm the caller's identity.
2. The method as described in Claim 1 wherein the second character string confirms the caller's identity only during a predetermined time period.
3. A method for enabling a caller to obtain access to one or more services via a telephone network by speaking first and second character strings each having one or more characters, comprising the steps of:
(a) prompting the caller to speak the first character string beginning with a first character and ending with a last character thereof; (b) generating speech feature data for each spoken character of the first character string; (c) applying the speech feature data and voice recognition feature transformation data to a voice recognition feature transformation to generate a firs set of parameters for each spoken character of the first character string, the first set of parameters for use in a voice recognition system; (d) applying the speech feature data and voice verification feature transformation data to a voice verification feature transformation to generate a second set of parameters for each spoken character of the first character string, the second set of parameters for use in a voice verification system;
(e) recognizing the first character string using the first set of parameters; (f) initially verifying the caller's identity using the second set of parameters generated for the first character string;
(g) prompting the caller to enter the second character string beginning with a first character and ending with a last character thereof;
(h) generating speech feature data for each spoken character of the second character string;
(i) applying the speech feature data and voice recognition feature transformation data to a voice recognition feature transformation to generate a first set of parameters for each spoken character of the second character string, the first set of parameters for use in a voice recognition system; and (j) recognizing the second character string using the first set of parameters.
4. The method of Claims 3 further including the step of determining if the recognized second character string is a password associated with the caller verified in Step (f).
5. The method as described in Claim 3 further including the step of periodically changing the second character string for confirming the identity of the caller.
