1. A speech recognition system comprising:

  • voice recognizing and processing means including a plurality of speech recognition neural networks that have previously learned different voice patterns to recognize given voice data, each of said speech recognition neural networks including means for judging whether or not a piece of input voice data coincides with one of the voice data to be recognized and outputting a recognition result and having means for outputting adaptation judgment data independent of the recognition result, the adaptation judgement data representing the adaptation in speech recognition;

    selector means receiving input voice data and data from said neural networks and responsive to the adaptation judgment data from each of said speech recognition neural networks for selecting one of said neural networks that has the highest adaptation in speech recognition; and

    output control means for outputting the result of speech recognition from the speech recognition neural network selected by said selector means.
