PROBLEM TO BE SOLVED: To provide a wireless microphone communication system that selects different bit lengths, so as to enhance the man-machine interface. SOLUTION: The wireless microphone communication system 100 is provided with a wireless microphone 101, that controls the time interval of a tone signal having a prescribed level and being generated intermittently at a prescribed time interval so as to set a start bit, High level data and Low level data and transmits the data and with a wireless microphone receiver 102, that integrates the level of the tone signal by each prescribed time, in the case of receiving a tone signal to detect the transmitted data on the basis of a change in the calculated integral value, and the wireless microphone 101 transmits the data to the wireless microphone receiver 102.
