User identification system using improved voice print identification processing

A method of operating a user identification validation system that verifies the identity of a user who provides a voice input to said user identification validation system, comprising the steps of:

• storing in a memory a plurality of user identification data entries, each of said user identification data entries serving to uniquely identifying a particular user and comprising at least one voice input segment provided by said particular user, comprising:
• indexing each of said plurality of user identification data entries by a sort key provided by said particular user,
• writing in each of said plurality of user identification data entries a prestored
• user provided voice input segment;
• converting, in response to a service requesting user accessing said user identification validation system, at least a portion of a voice input provided by said service requesting user into a text string;
• identifying at least one of said plurality of user identification data entries stored in said means for storing that contains data matching said text string;
• and
• operating a voice recognition system to compare said voice input provided by said service requesting user with said at least one of said plurality of user identification data entries to validate the identity of said service requesting user.

A user identification validation system that verifies the identity of a user who provides a voice input to said user identification validation system, comprising:

• a memory for storing a plurality of user identification data entries, each of said user identification data entries serving to uniquely identifying a particular user and comprising at least one voice input segment provided by said particular user:
• means for storing a string of text as a sort key in said user identification data entry corresponding to said particular user, which sort key is provided by said particular user;
• voice to text conversion means, responsive to a service requesting user accessing said user identification validation system, for converting at least a portion of a voice input provided by said service requesting user into a text string;
• means for identifying at least one of said plurality of user identification data entries stored in said memory that contains a sort key that matches said text string comprising:
• means for generating data indicative of all of said sort keys stored in said memory that differ from said text string by less than a predetermined amount,
• means, responsive to said generated data, for presenting said voice recognition system seriatim with each of said user provided voice input segments corresponding to each of said all of said sort keys stored in said memory that substantially match said text string to enable said voice recognition system to identify a match between said voice input provided by said service requesting user with a one of said user provided voice input segments corresponding to each of said all of said sort keys stored in said memory that substantially match said text string;
• and
• a voice recognition system that is operational to compare said voice input provided by said service requesting user with said at least one voice input segment that is stored in said at least one of said plurality of user identification data entries to validate the identity of said service requesting user.
