Certain embodiments may include methods and systems for receiving first audio data from a plurality of microphones disposed in a cabin of a vehicle, calculating phase differences between the first audio data received from different ones of the plurality of microphones, determining a location of a source of the first audio data based on the calculated phase differences, isolating second audio data received from the plurality of microphones, taking into account the determined location of the source, and controlling a function of the vehicle based on the isolated second audio data. Some embodiments can further include detecting voice data in the second audio data based on audio characteristics of the second audio data, and determining a voice command in the voice data, where the controlling the function of the vehicle is based on the voice command in the voice data in the second audio data.
