Digital Voice Systems, Inc. has twenty-five years of experience in providing state-of-the-art digital speech technology and has earned a worldwide reputation as a leader in the development of low bit rate vocoders. DVSI is the owner and developer of the IMBE™, AMBE®, AMBE+™, and AMBE+2 speech coding algorithms which operate at low bit rates (2.0 - 9.6 kbps) and deliver high quality speech under demanding conditions. DVSI has considrable experience in implementing these algorithms on many different DSP platforms and ARM devices.
Numerous independent studies have shown that DVSI's vocoder technology can provide substantially the same quality as today's digital cellular systems at roughly half the bit rate. This substantial capacity advantage is the key reason that DVSI vocoders have been chosen for use in virtually every Mobile Satellite Communications system including Inmarsat BGAN and GVS/Isatphone, Iridium, OPTUS, ACeS, Thuraya, GlobalStar, and major Land Mobile Radio programs such as APCO Project 25, DMR, dPMR and many others.
