1. A method of creating a production script for interactions between participants and an automated data collection system, comprising the steps of:

  • conducting a trial in which a group of subjects provides utterances to the automated data collection system which is operative in accordance with an experimental script;

    recording the utterances provided by the test subjects during the trial;

    evaluating a recognition rate attained by the automated data collection system;

    if the recognition rate is below an acceptability threshold, tuning the experimental script, repeating the step of conducting a trial using the tuned experimental script and the recorded utterances instead of utterances from a group of test subjects, and repeating the step of evaluating the recognition rate; and

    if the recognition rate is at least the acceptability threshold, using the experimental script, as selectively tuned, as the production script.
