Abstract
Abstract A production script for interactions between participants and an automated data collection system is created by selectively tuning an experimental script through successive trials until a recognition rate of the system is at least an acceptability threshold. The data collection system uses a semi-constrained grammar, which is a practical accommodation of a larger range of possible inputs than a menu. The data collection system collects data by recognizing utterances from participants in accordance with the production script.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
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.
Claim 2
Independent Claim
138 words
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.
Claim 3
Independent Claim
124 words
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 and which interacts with an external system to recognize utterances; 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 repeating the step of evaluating the recognition rate; and if the recognition rate is at least the acceptability threshold, using the experiental script, as selectively tuned, as the production script.
Claim 4
Independent Claim
124 words
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 and which interacts with an external system to recognize utterances; 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 repeating the step of evaluating the recognition rate; and if the recognition rate is at least the acceptability threshold, using the experiental script, as selectively tuned, as the production script.
Claim 5
Independent Claim
133 words
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; 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 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; wherein the script has a prompt and a corresponding recognition grammar that includes a semi-constrained vocabulary recognition response grammar.
