Advanced Speech Encoding (ASE)
Abstract
(U) The Advanced Speech Encoding (ASE) program achieved an order of magnitude reduction of voice communication bit rates over current state-of-the-art voice encoders (VOCODER) in noisy military environments. Such a reduction significantly decreased the probability of detection of transmitted signals and also decreased the required transmit energy, thereby increasing battery lifetime. The program pursued two novel approaches toward achieving its goal. Multiple noise-immune sensors combined with traditional coding algorithms; and communication without acoustic information achieved by extracting laryngeal and sublingual muscle signals that are produced when a person generates sub-vocal speech. The ASE technology is transitioning to the Special Operations Command and the Communications and Electronics Command of the U.S. Army.
