The invention provides an escalator accident automatic voice brake device. According to the escalator accident automatic voice brake device, the connecting wire ends of voice sensors mounted on the left side and the right side of an escalator are connected with an or circuit, a signal processing circuit, a voice emotion recognition circuit and a summing unit in series through wires, and the summing unit is connected with an escalator stop circuit and a loudspeaker in parallel. A volume average value circuit and a comparator are connected in series by arranging another wire on the wire for connecting the signal processing circuit with the voice emotion recognition circuit, and are connected with the summing unit. During operation of the escalator after mounting, once the escalator gets an accident, the circuits of the escalator can be disconnected automatically to stop the escalator operating via voice calls for help.
