Abstract

A distributed voice application execution environment system conducts a voiceprint analysis when a user initially begins to interact with the system. If the system is able to identify the user through a voiceprint analysis, the system immediately begins to interact with the user utilizing voice applications which have been customized for that user.

Claims

1. A method of identifying a user in a system that performs voice applications, comprising:

receiving spoken input from an unidentified user;

conducting a voiceprint analysis using the spoken input received from the unidentified user;

determining if a voiceprint score from the voiceprint analysis is above a threshold confidence value;

interacting with the user using at least one voice application that has been customized for the user if the voiceprint score from the voiceprint analysis is above the threshold confidence value; and

interacting with the user using generic one voice applications if the voiceprint score from the voiceprint analysis is below the threshold confidence value.
