1. Title of invention: signal security device 2. SUMMARY OF THE INVENTION: The voice signal is divided into a plurality of frequency bands, and the respective frequency bands are transmitted at different times, at which point the voice signal will lose its intelligibility. In such a device, the transmission time in the frequency band mainly occupied by the consonants is at least longer than the average one syllable time compared with the transmission time in the frequency band mainly occupied by vowels. The above is the hair
