Abstract

PURPOSE:To allow hand-free service through a simplex operation transmitter and receiver, by equipping the transmitter and receiver with a voice recognizing circuit which recongizes a specific voice signal, and performing transmission/ reception switching by the output signal of said circuit. CONSTITUTION:When a voice is inputted from a microphone speaker 1, the voice recognizing circuit 8 which recognizes the specific voice recognizes it. In this case, a voice switching circuit 3 and a high-frequency switching circuit 6 are operated by the output of the circuit 8 and a transmission part 4 is actuated to maintain a transmission state. When the transmission ends and some specific voice, e.g. ''Roger'' or ''Over'' is inputted, the voice recognizing circuit 9 receives it. In this case, the actuation of the transmission part 4 is stopped by the output of the circuit 9 and while circuits 3 and 5 are released, a reception part 5 operates to enter a reception state. Thus, the hand-free service is allowed and the simplex operation transmitter and receiver which eliminates a break of voice and is easy to use is obtained.

By adding a voice recognition circuit that recognizes a certain voice signal (that is, a voice signal corresponding to a certain voice pattern)'f, it is possible to make phone calls free of calls. Moreover, it is an object of the present invention to provide a transmitting/receiving device for a simple communication system with fewer audio interruptions.

により。On the other hand, FIG. 2 shows an example of the configuration of a simplex system transmitter/receiver according to an embodiment of the present invention. When a voice is input from a microphone speaker, a voice recognition circuit 8 that recognizes a specific voice signal recognizes it. Based on the output of the voice recognition circuit 8 at this time.
