For a mobile robot to serve people in actual environments, such as a living room or a party room, it must be easy to control because some users might not even be capable of operating a computer keyboard. For non-expert users, speech recognition is one of the most effective communication tools when it comes to a hands-free (human-robot) interface. This paper describes a new mobile robot with hands-free speech recognition. For a hands-free speech interface, it is important to detect commands for a robot in spontaneous utterances. Our system can understand whether user’s utterances are commands for the robot or not, where commands are discriminated from humanhuman conversations by acoustic features. Then the robot can move according to the user’s voice (command). In order to capture the user’s voice only, a robust voice detection system with AdaBoost is also described.
