This report on the simulation of VAAM includes the full design of the preprocessor as implemented on the TR-48 analog computer and also the design of the programs utilized by the Digital Operations System-350. For reasons of efficiency the Phase I effort was broken into three tasks. First, recordings of various speakers voicing the vocabulary words were digitized and punched on paper tape. Second, the paper tapes were input to the DDP-24 digital computer to train VAAM to recognize the vocabulary. Third, the reference functions created in the learning task were evaluated by using voiced inputs directly on-line with the full system. It was found that the sample of single voicings by 26 speakers was an inadequate training set for a good extrapolation recognition rate. The extrapolated recognition rate was approximately 55 percent, ranging from 35 to 80 percent for different speakers. An attempt at improving results by on-line training pointed out the inefficiency of this mode of operation, and the improvement was small. The conclusions are that the approach of the Andromeda Inc. algorithm is feasible but more training is required. The training must be automated by adding some mass storage medium such as digital magnetic tape to the system. Author
