Title:
SPEAKER RECOGNITION IN A MULTI-SPEAKER ENVIRONMENT AND COMPARISON OF SEVERAL VOICE PRINTS TO MANY
Document Type and Number:
WIPO Patent Application WO2004109657
Kind Code:
B1
Abstract:
One-to-many comparisons of callers' voice prints with known voice prints to identify any matches between them. When a customer communicates with a particular entity, such as a customer service center, the system makes a recording of the real-time call including both the customer's and agent's voices. The system segments the recording to extract at least a portion of the customer's voice to create a customer voice print, and it formats the segmented voice print for network transmission to a server. The server compares the customer's voice print with multiple known voice prints to determine any matches, meaning that the customer's voice print and one of the known voice prints are likely from the same person. The identification of any matches can be used for a variety of purposes, such as determining whether to authorize a transaction requested by the customer.
