1. A computer implemented method of analyzing dialog between a user and an interactive application having dialog turns, wherein a turn comprises a prompt from the application and a response received from the user, the method comprising:

  • accessing stored information indicative of audible responses to prompts received from the at least one user during a plurality of dialog turns between the application and at least one user;

    identifying, using a processor of the computer, instances from the accessed information where the application determined a response was received from the at least one user before an associated prompt had completed, wherein the accessed information comprises information related to operation of the application with a first grammar to recognize the response;

    identifying whether the response was received in a particular limited time period from when the associated prompt began; and

    if the response was received in the limited time period, determining whether the response included one or more terms from the associated prompt by performing recognition on the response using a second grammar having more information related to grammar of a language than the first grammar, wherein terms from the associated prompt are added to the second grammar.
