Abstract: The frogman underwater voice communicator is an essential equipment for underwater operation of frogman, which has attracted more and more attention in the military and civil fields. In this paper, the research status and achievements of product and technology about frogman underwater voice communication system at home and abroad are firstly introduced, then the key problem in the development of frogman underwater voice communication are discussed in detail, and it is pointed out that the modulation and demodulation technology based on digital signal processing has been widely applied in frogman underwater acoustic voice communication system. This technology can effectively reduce the interference factors such as the multi-path effect and ocean ambient noise in frogman underwater acoustic voice communication, to improve the quality of the communication. This technology has become the main research direction. In terms of the structure, the future development trend of the frogman underwater acoustic voice communicator is to transform it from split-type and large volume to modularization, miniaturization, low power consuming and integration.
