Speech recognition of customer identifiers using adjusted probabilities based on customer attribute parameters
First Claim
1. A method of recognizing a customer identifier comprising the steps of:
- (a) receiving a speech signal from a customer;
(b) generating a first plurality of customer identifier choices from the speech signal and a probability associated with each of the first plurality of choices;
(c) querying a database using said first plurality of choices, the database having stored thereon a plurality of customer attribute parameters indexed to a second plurality of customer identifier choices;
(d) retrieving one or more customer attribute parameters;
(e) adjusting the probabilities based on said retrieved customer attribute parameters; and
(f) selecting the customer identifier from the first plurality of choices based on the adjusted probabilities.

Abstract
A speech recognition system recognizes a customer identifier received as a speech signal from a customer. The system generates a first plurality of customer identifier choices from the speech signal and a probability associated with each of the first plurality of choices. The system includes a database having stored thereon a plurality of customer attribute parameters indexed to a second plurality of customer identifier choices. The system queries the database using the first plurality of choices, and retrieves one or more customer attribute parameters from the database. The probabilities are adjusted by the system based on the retrieved customer attribute parameters. The customer identifier is then selected from the first plurality of choices based on the adjusted probabilities.

12. A speech recognition system for recognizing a customer identifier comprising:
-
a speech processing computer that generates a first plurality of customer identifier choices from a speech signal and a probability for each customer identifier choice; and a database coupled to said computer, said database having stored thereon a plurality of customer attribute parameters indexed to a second plurality of customer identifier choices; wherein said speech processing computer selects one of the first plurality of customer identifier choices as said customer identifier based on the probabilities and one or more of said customer attribute parameters which adjust said probabilities. - View Dependent Claims (13, 14, 15, 16, 17)
