Abstract: Systems and methods are provided for improving acoustic echo cancellation in a cabin of a vehicle. A source of far end speech is detected using a far end speech control module. A main beam directed at a speaking occupant and based on the far end speech is formed using a beam forming module. An echo cancelation filter is formed based on the far end speech using an acoustic echo cancellation module. An audible communication from the speaking occupant is received with at least one microphone in a microphone array to generate a microphone signal. The microphone signal is filtered using a spatial filter based on the main beam and the echo cancellation filter to generate a cabin output signal which is broadcasted to the source of far end speech.

Abstract: A system and methods are disclosed for improving communication between occupants in a cabin of a vehicle. A source location of a speaking occupant and an output location of a loudspeaker is identified using a microphone array. A beam forming module directs a main beam at the source location and a null beam at the output location. An audible communication from the speaking occupant is received with the microphone array, filtered with a spatial filter based on the main beam and the null beam and broadcast over the loudspeaker.
