Home robots will help us household works in the living environment. The robots need to listen to user's order and communicate with him/her. For the interaction between the user and the robot, we developed the omni-directional auditory process. This process allows the robot recognize the direction of the sound source of user's voice - that is the direction of user. It extracts the sound stream of user's speech, and recognizes the contents of the speech. We implemented this process into ApriAlpha™ V3 - Sharp Ear Robot, and exhibited in Aichi Expo 2005. This paper describes the summary of ApriAlpha™ V3 and the omni-directional auditory process - the estimation of the voice direction with the function and the experimentation of the process.
