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.

Script opérationnel pour interactions entre des participants et un système de collecte automatique de données, créé par réglage d'un script expérimental au moyen d'essais successifs jusqu'à ce que le système atteigne un taux de reconnaissance au moins acceptable. Le système de collecte de données utilise une grammaire semi-contrainte, qui constitue une prise en charge pratique d'une gamme plus vaste d'entrées possibles qu'un menu. Ce système recueille des données par reconnaissance des énoncés formulés par les participants conformément au script opérationnel.
