Abstract

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
