PURPOSE: A voice guide apparatus for an emergency exit route in a building is provided to detect the entry and the entry direction of people through light emitting and receiving units and provide an emergency exit route even for the blind. CONSTITUTION: A voice guide apparatus for an emergency exit route in a building comprises light emitting units(10), light receiving units(20), a signal processing unit, a voice memory unit, and a voice output unit. The light emitting units are arranged at regular intervals along both side walls of a passage in a building. The light receiving units are arranged facing the respective light emitting units and receive signals from the light emitting units. The signal processing unit determines the entry of a person according to the signal sensed by the outermost light receiving unit and the moving direction of the person from the time difference between the outermost light receiving unit and the adjacent light receiving unit. The voice memory unit stores voice information corresponding to the entry and moving direction of the person. The voice output unit outputs voice information from the voice memory unit according to the entry and moving direction of the person. |
