Fig. 1 is a principle diagram of a desirable voice secret communication device according to the present invention, Fig. 2 is an example of the original waveform of a voice signal to be transmitted to the other party using this device, and Fig. 3 is a diagram showing the principle of the voice signal transmitted to the other party using this device. An example of the waveform actually transmitted when transmitting an audio signal, Figure 4 is the waveform of the audio signal that the legitimate receiver receives and reproduces the signal in Figure 3, and Figure 5 is an example of the waveform that is actually transmitted when transmitting the audio signal. This shows an example of the waveform of a signal that was accidentally generated by an eavesdropper who attempted to restore and reproduce the data without knowing the replacement order. 1...Microphone, 2...Analog/digital converter, 3...Memory, 4...Digital/analog converter, 5...Control device, 6...Transmitter, 11...Sound pressure waveform, 12...
... Time division position used for conversion, 13 ... Name indicating the order of division, 21 ... Sound pressure waveform, 22
... Time division position used for conversion, 23 ... Name indicating the order of division, 31 ... Sound pressure waveform, 3
2...Correct time break position used for playback, 3
3... Name indicating the order of division, 41... Waveform of sound pressure, 42... Incorrect time division position used for reproduction, 43... Name indicating the order of division.

適当な時間間隔に区切り、区切られた信号を取り
入れた順序と異なる順序で送信することによつて
、傍受者に解釈不能のすることを特長とする音声
秘話装置。 Incorporates audio signals and stores them in the device,
A voice secret communication device characterized by dividing signals into appropriate time intervals and transmitting the divided signals in an order different from the order in which they were taken in, thereby making it impossible for an eavesdropper to interpret the signals.
