Realtime detection and identification of plural speakers using a microphone array

Voices are used as primary media in human communication. A human voice is a sound generated by the complex movements of the vocal organs, and is the most important media employed for the communication in the day life to logical discussions. A human is able to detect the position of a source sound in 3D space by perceiving the time difference reaching to the both ears. Furthermore we can selectively listen to an objective voice in the crowds. This paper presents a realtime detection and identification of a particular person among plural speakers using a microphone array. The system identifies the position of a particular speaker, and enhances the voice signal selectively.
