A system for capturing a user's voice, including a plurality of microphones disposed about a vehicle cabin, each of the plurality of microphones generating a microphone signal, wherein the vehicle cabin defines a plurality of seating positions; a voice-activity detector configured to detect when, at least, a user seated in a target seat of the plurality of seating positions is speaking; and an adaptive beamformer configured to receive the microphone signals from the plurality of microphones and to generate, based on the microphone signals and a noise coherence matrix, an estimate of the acoustic signal at the target seating position, according to an adaptive beamforming algorithm, wherein the noise coherence matrix ceases to be updated when, according to the voice-activity detector, the user seated in the target seating position is speaking.
