Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and a system for tracking speakers with a simple structure, which can be executed in an environment such as an interior of a travelling vehicle and can distinguish the sound of a speaker through short communication from the sound of a speaker through long communication both through a loudspeaker of a hand-free phone system. SOLUTION: The system that has sound sensors and tracks at least one speaker to efficiently detect the sound from the speaker, is provided with a) a beam former actively coupled with the sound sensors to receive an electric signal and with b) a comparator that is actively coupled with the beam former to compare the power of beams with each other for determination of the most preferable direction to detect sound of the speakers.
