Audio sensors and low-complexity recognition technologies for soldier systems

چکیده
The use of audio sensors for soldier systems is examined in detail. We propose two applications, speech recognition and speaker veri cation. These technologies provide two functions for a soldier system. First, the soldier has hands-free operation of his system via voice command and control. Second, identity can be veri ed for the soldier to maintain the security integrity of the soldier system. A low complexity, high accuracy technology based upon averaging a discriminative classi er over time is presented and applied to these processes. For speaker veri cation of the soldier, the classi er is used in a text-prompted mode to authenticate the identity of the soldier. Once the soldier has been authenticated, the interface can then be navigated via voice commands in a speaker independent manner. By using an arti cial neural network structure, a high degree of accuracy can be obtained with low complexity. We show the resulting accuracy of the speaker veri cation technology. We also detail the simulation of the speech recognition under various noise conditions.
