1. A system for processing natural language utterances, comprising:

  • a multimodal device configured to;

    receive a natural language utterance; and

    subsequently receive a follow-up multimodal input;

    a speech recognition engine configured to recognize one or more words from the natural language utterance;

    a parser configured to generate an interpretation of the natural language utterance from the one or more recognized words, and further configured to generate a request based on the interpretation of the natural language utterance;

    a domain agent configured to process the generated request; and

    an adaptive misrecognition engine configured to;

    monitor one or more actions associated with the domain agent processing the request; and

    determine that the interpretation of the natural language utterance was incorrect if one or more of the monitored actions include the follow-up multimodal input being presented proximate in time to the prior natural language utterance.
