Abstract
Methods and systems are provided for filtering sound. A position sensor determines positions of a plurality of occupants in a defined space. Multiple microphones receive sound and generate corresponding audio signals. A processor in communication with the microphones and the position sensor receives the positions of the occupants and the audio signals. The processor determines which of the occupants are engaging in speech and applies a temporal-spatial filter to the audio signals to generate a plurality of output signals corresponding respectively to each occupant of the defined space.
