1. A method of circumstantial speech recognition in a vehicle, the method comprising the steps of:
- detecting user interaction with a particular one of a plurality of different vehicle devices located in the vehicle;
identifying the particular vehicle device as a candidate for user-intended automatic speech recognition (ASR) control based on receiving speech from the user within an elapsed time following the detection of the user interaction; and
thencarrying out speech recognition on the received speech using an automatic speech recognition system that is configured based on the identified vehicle device.

Abstract
A method of circumstantial speech recognition in a vehicle. A plurality of parameters associated with a plurality of vehicle functions are monitored as an indication of current vehicle circumstances. At least one vehicle function is identified as a candidate for user-intended ASR control based on user interaction with the vehicle. The identified vehicle function is then used to disambiguate between potential commands contained in speech received from the user.

8. A method of circumstantial speech recognition in a vehicle based on user interactivity with the vehicle, the method comprising the steps of:
-
receiving speech from a user in a vehicle via a microphone pre-processing the received speech; decoding the pre-processed speech into recognized speech data using an automatic speech recognition system; monitoring a plurality of different vehicle devices for interaction by the user using at least one processor located in the vehicle; and
thenidentifying a vehicle device for user-intended automatic speech recognition (ASR) control if the user has interacted with the identified vehicle device within a predetermined elapsed time; and
thencontrolling the identified vehicle device using the recognized speech data. - View Dependent Claims (9, 10, 11, 12)

13. A method of circumstantial speech recognition in a vehicle based on user interactivity with the vehicle, the method comprising the steps of:
-
monitoring a plurality of different vehicle devices for interaction by a user using at least one processor located in the vehicle; and
thenidentifying a vehicle device for user-intended automatic speech recognition (ASR) control based on user interaction with the vehicle device; and
thenreceiving speech from the user via a microphone located in the vehicle, the received speech being received within an elapsed time following the user interaction; and disambiguating between two or more possible commands contained in the speech based at least in part on the user interaction with the identified vehicle device. - View Dependent Claims (14, 15, 16, 17, 18)
