摘要: Methods and systems are provided for receiving desired sounds. The system includes a position sensor configured to determine an occupant of engaging in speech within defined space transmit the speaking position. A plurality microphones receive sound from audio signals corresponding received sound. processor, communication with microphones, is signals, apply beamformer direct microphone beam toward position, generate output signal.
