15. Training apparatus as in claim 13, further including: matching means for scoring closeness of matches between each user generated signal and pattern information representing that user generated signal's corresponding expected word and for producing a score representing the closeness of each such match; and means, responsive to the production by said matching means of a score for the match of a given user generated signal against that user generated signal's expected word which is above a given level, for incorporating information from that user generated signal into the pattern information representing that expected word.
13. Training apparatus for helping a user improve his or her use of a word recognition system, which recognition system scores matches of signal models for each of a plurality of words against each of a succession of user generated signals; which recognition system produces a succession of outputs corresponding to the succession of user generated signals, each such output representing as the recognized word the word whose signal model scored best against the corresponding one of said user generated signal, with such an output being considered a mis-recognition when that output represents as the recognized word a word other than that actually represented by the output's corresponding user generated signal and which recognition system responds to the receipt of a correction command from a user when a mis-recognition has occurred by correcting that mis-recognition, that is, by changing the mis-recognition's output to remove the representation as the recognized word of a word other than that actually represented by that output's corresponding user generated signal; said training apparatus comprising: means for instructing the user to generate a user generated signal for each of a corresponding succession of expected words; training output means for responding to the user's successive generation of said user generated signals by producing a corresponding succession of outputs, some of which represent as the recognized word the expected word corresponding to the output's user generated signal, and some of which represent a simulated mis-recognition of that expected word by representing as the recognized word for the output's user generated signal a word other than that signal's corresponding expected word; means for receiving a correction command from a user indicating that the user desires to correct such a simulated mis-recognition when that mis-recognition has occurred and for responding to the receipt of such a correction command by changing the mis-recognition's output by removing that output's representation as the recognized word of a word other than the output's corresponding expected word; and correction monitoring means for monitoring whether or not the user responds to a simulated mis-recognition by entering a correction command to correct that mis-recognition and for providing an output to the user to notify him or her when he or she fails to correct such a simulated mis-recognition.
