In-car infotainment systems are controlled by voice commands, whether that is to play music or make a call.
But a car can be noisy: traffic, general road noise, other passengers talking all disrupt voice calls and inhibit in-car speech recognition performance. Existing solutions based on noise suppression may reduce listener fatigue but won’t improve speech intelligibility and won’t remove competing speech.
Technology that relies on beamforming only focusses a device’s microphones in a specific direction, amplifying all sounds in that direction.
