We propose a beamforming method that is applicable to near sound fields, where a filter-and-sum microphone array which maintains better quality for the target sound than the conventional delay-and-sum array, and describe a real-time implementation that includes steering of the beam to detected talker locations. With the use of a microphone array, our system also reduces levels of noise, to achieve high-quality sound acquisition; furthermore, it allows the talker to be in any position. Computer simulation and experiments show that our method will be effective in teleconferencing systems.
