Zusammenfassung:	A compact digital signal processor based on the architecture of the ICL Distributed Array Processor (DAP) is under development for MOD applications in Radar, ESM, Image Processing, etc. This Memorandum examines its applicability to speech recognition. In such a distributed processor, optimum mapping of the problem on to the array of processors is vital for efficiency. Three mappings of a dynamic time warping algorithm for isolated word recognition are examined, leading to a feasbile real time capability for continuous speech processing. The compatibility found between dynamic programming methods and this class of machine enlarges the scope of signal processing algorithms foreseen as amenable to parallel processing. (Author)
