ABSTRACT:
A speech recognition system can recognize a plurality of voice data having different patterns. The speech recognition system has a voice recognizing and processing device including a plurality of speech recognition neural networks that have previously learned different voice patterns to recognize given voice data. Each of the speech recognition neutral networks is adapted to judge whether or not input voice data coincides with one of the voice data to be recognized. Each neural network then outputs adaptation judgment data representing the adaptation in speech recognition. A selector responsive to the adaptation judgment data from each of the speech recognition neural networks selects one of the neural networks that has the highest adaptation in speech recognition. An output control device outputs the result of speech recognition from the speech recognition neural network selected by the selector.
