This paper proposes virtual wireless microphone (VWM) as a novel application of computer vision and signal processing. It integrates real-time face tracking and sound signal processing. Utilizing a microphone array, VWM can dynamically realize “acoustic focus” at human face. VWM is intended to be used as a speech signal input method for human computer interaction, especially for autonomous intelligent agent that interacts with humans like as “digital secretary”. Utilizing VWM, the agent can clearly listen human speaker's voice remotely as if a wireless microphone was put just in front of the speaker
