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.
