Actuator control of adjustable elements by speech localization in a vehicle
First Claim
Patent Images
1. A system for adjusting an adjustable element associated with a vehicle, the system-comprising:
- an actuator adapted to adjust the adjustable element;
at least one microphone array for detecting speech from a speaker within the vehicle and generating speech signals corresponding to the detected speech;
a localization detector configured to determine a position of the speaker based on the speech signals and configured to output a localization signal that encodes the determined position of the speaker;
a speech recognition system configured to receive the speech signals and output a command signal based on content of the speech signals; and
a controller for controlling the actuator, the controller adapted to receive the localization signal and the command signal and to control the actuator to adjust the state of the adjustable element on the basis of the determined position of the speaker encoded in the localization signal and the command signal, where the controller is configured to operate the actuator in response to a change in the position of the speaker being greater than a predetermined amount.

13. A method of adjusting an adjustable element associated with a vehicle, the adjustable element including an actuator for adjusting the adjustable element, the method comprising:
-
providing at least one microphone array; detecting speech emanating from a first person by the at least one microphone array such that the at least one microphone array produces voice signals corresponding to the detected speech; determining a position of the first person based on the voice signals; encoding the determined position of the first person in a localization signal; providing a speech recognition system adapted to recognize speech input commands uttered by the first person; determining which adjustable element of a plurality of adjustable elements is to be adjusted based on the received input command; and controlling the actuator of the adjustable element to adjust the adjustable element to a position commensurate with the determined position of the first person encoded in the localization signal, the adjustable element adjusted in response to a change in the position of the first person being greater than a predetermined amount. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
