System and method for activating a voice assistant for a vehicle

A method for activating a voice assistant of a vehicle, the method comprising:

• transmitting a plurality of original training signals on a plurality of subcarriers using a first wireless module;
• receiving a plurality of propagated training signals using a second wireless module;
• determining a deviation between the plurality of original training signals and the plurality of propagated training signals;
• identifying a motion marker based at least in part on the deviation, wherein identifying the motion marker further comprises:
• determining a plurality of channel state information (CSI) values based at least in part on the deviation between the plurality of original training signals and the plurality of propagated training signals;
• and
• identifying the motion marker based at least in part on the plurality of CSI values, wherein the motion marker includes at least one of:
• a low-fidelity motion marker and a high-fidelity motion marker;
• and
• activating the voice assistant of the vehicle to receive a voice command using a microphone based at least in part on the motion marker.

A system for activating a voice assistant of a vehicle, the system comprising:

• a microphone configured to receive voice commands;
• a first wireless module, wherein the first wireless module is a first digital wireless local area network (WLAN) transceiver system configured to implement a wireless communication protocol;
• a second wireless module, wherein the second wireless module is at least one of:
• a second digital wireless local area network (WLAN) transceiver system configured to implement the wireless communication protocol and a signal conversion device configured to convert signals between at least two frequency bands;
• a controller in electrical communication with the microphone, the first wireless module, and the second wireless module, wherein the controller is programmed to:
• transmit a plurality of original training signals on a plurality of subcarriers using the first wireless module;
• receive a plurality of propagated training signals using the second wireless module;
• determine a deviation between the plurality of original training signals and the plurality of propagated training signals;
• determine a plurality of channel state information (CSI) values based at least in part on the deviation between the plurality of original training signals and the plurality of propagated training signals;
• and
• identify a motion marker in the plurality of CSI values, wherein the motion marker includes at least one of:
• a low-fidelity motion marker and a high-fidelity motion marker;
• and
• activate the voice assistant of the vehicle to receive a voice command using the microphone based at least in part on the motion marker.
