System for identifying and adapting a TV-user profile by means of speech technology
First Claim
1. A control system for audio/video equipment comprising:
- speaker verification/identification module for ascertaining the identity of a system user based on the user'"'"'s speech;
a user profile database that stores user-specific data based on the identity of a system user and retrieves said data in response to operation of said speaker verification/identification module;
said user profile database being further configured to store at least one user preference information selected from the group consisting of preferred channels, blocked channels and combinations thereof;
a speech recognizer and language parser system for extracting a semantic representation of spoken information provided by the user;
a command module coupled to said speech recognizer and language parser system for providing control signals to said audio/video equipment based on said extracted semantic representation;
said command module being further responsive to said user preference information in providing said control signals; and
wherein at least one of said speech recognizer and language parser system and said command module uses said user-specific data.

Abstract
Speech input supplied by the user is evaluated by the speaker verification/identification module, and based on the evaluation, parameters are retrieved from a user profile database. These parameters adapt the speech models of the speech recognizer and also supply the natural language parser with customized dialog grammars. The user'"'"'s speech is then interpreted by the speech recognizer and natural language parser to determine the meaning of the user'"'"'s spoken input in order to control the television tuner. The parser works in conjunction with a command module that mediates the dialog with the user, providing on-screen prompts or synthesized speech queries to elicit further input from the user when needed. The system integrates with an electronic program guide, so that the natural language parser is made aware of what programs are available when conducting the synthetic dialog with the user.

29. A method for controlling the operation of audio/video equipment comprising the steps of:
-
processing input speech from an equipment user to ascertain the user'"'"'s identity; and
maintaining a data store of user preference information selected from the group consisting of preferred channels, blocked channels and combinations thereof;
using said ascertained user'"'"'s identity to retrieve said preference information; and
controlling the operation of said equipment based on said preference information. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38)
storing profile information based on the identity of an equipment user, said profile information identifying at least one predetermined program selection; and
blocking said equipment from accessing said at least one predetermined program selection based on said ascertained identity.
