ABSTRACT:
A command input device to be used in a voice controllable elevator system, capable of enabling a user to perform a command input in voice more easily and accurately. The device includes a sensor for detecting presence of the user within a prescribed proximity to a microphone; and a unit for outputting the command recognized by a speech recognition unit to an elevator control unit of the elevator system in response to termination of detection of the user by the sensor. In addition, the speech recognition unit recognizes the last command given by the user while the sensor is detecting the presence of the user. The user can correct a command incorrectly recognized by the speech recognition unit by re-entering the command while the sensor is detecting the presence of the user.
