A speech recognition system includes a speech-response capability for responding to sounds which appear to match models of spoken words by performing functions associated with such words. This speech response can be turned on or off. If the system detects both that speech response is off and that no indication is stored that the off state has been confirmed by a user, it performs a confirmation process. This prompts the user to utter a phrase confirming whether or not speech response is to be off; turns speech response on so it can respond to the user's confirmation utterance; determines whether to leave speech response on or off in response to the word which the speech response selects as corresponding to the user's confirmation utterance; and responds to such a determination that speech response is to be turned off, both by turning it off and by storing an indication that the off state has been confirmed by the user. In some embodiments, the system can execute user written programs which can include instructions for turning speech response on or off. In this case, the system can delay the start of a confirmation process until after the execution of such a program, to allow such programs to temporarily turn off speech response without requiring user confirmation. In some embodiments, the user can select whether to deactivate the feature which causes a confirmation processes to occur whenever speech response has been turned off without confirmation.

[ What we claim is:] [1.] A computerized speech recognition system comprising:speech-response means including:means for receiving acoustics signals representing sounds received by a microphone;recognition means for pattern matching said acoustic signals against models of vocabulary words, to select, based on said pattern matching, which vocabulary words, if any, most probably correspond to those signals; andmeans for responding to a selection of a given vocabulary word as most probably corresponding to a given acoustic signal by performing a function associated with that vocabulary word;on-off means for selectively setting the speech response means to an on or off state in which said speech response means, respectively, either can or cannot, respond to sounds by performing said associated functions;means for storing confirmation information which indicates whether or not an off state of said speech response means has been confirmed by the user;confirmation means for performing a confirmation process including:first means for prompting the user to utter a phrase of one or more words confirming whether or not the user wants said speech response means to be in the off state;second means for causing said on-off means to set said speech response means to an on state so said speech response means can respond to an utterance the user makes in response to said prompt;third means for determining whether to place said speech response means in said on or off state in response to the vocabulary word selected by the recognition means as corresponding to an acoustic signal received after said prompt;fourth means for responding to such a determination to place said speech response means off, by causing said on-off means to set said speech response means to said off state and by storing confirmation information indicating that the off state has been confirmed by the user; andmeans, responsive to the combination of said speech response means being in said off state and said confirmation information indicating that the off state has not been confirmed by the user, for initiating said confirmation process in which said first, second, third, and forth means each perform their respective function.
