This paper describes the use of optical correlation techniques for isolated word recognition. The development system uses an acoustooptic deflector coupled with a photographic film template 'memory' in an optical system to achieve recognition times of 1/100 to 1/1000 real time. The parallel processing capability of optics is combined with the high density storage features of film to yield these recognition rates in a compact system.
