System and method for optimizing speech recognition in a vehicle
First Claim
1. A system for optimizing speech recognition in a vehicle, said system comprising:
- a microphone located in a vehicle for receiving input speech commands from a passenger;
a speech recognizer for recognizing the received speech commands;
a speech recognition grammar database comprising a plurality of stored grammars relating to known commands;
an occupant detector for detecting location of one or more passengers in a zone of the vehicle; and
a controller for processing the input speech commands to identify the received speech commands based on a comparison with the stored grammars in the grammar database, wherein the controller controls the amount of stored grammars that are processed based on the detected location of the one or more passengers in the vehicle.

Abstract
A system is provided for controlling personalized settings in a vehicle. The system includes a microphone for receiving spoken commands from a person in the vehicle, a location recognizer for identifying location of the speaker, and an identity recognizer for identifying the identity of the speaker. The system also includes a speech recognizer for recognizing the received spoken commands. The system further includes a controller for processing the identified location, identity and commands of the speaker. The controller controls one or more feature settings based on the identified location, identified identity and recognized spoken commands of the speaker. The system also optimizes on the beamforming microphone array used in the vehicle.
