Abstract
A system and method for tracking and recognizing multiple desired acoustic signals and processing the multiple signals with a single microphone is disclosed. The microphone includes multiple transducer elements, each of which produces a distinct electrical signal. The electrical signal is converted to a digital signal and beamforming and digital signal processing is performed on the electrical signals. The signals are then analyzed for the presence of speech. In the case where speech is present in multiple signals, the speech containing signals are then mixed for outputting.
