Communication-field mechanism design is to design a mechanism including rules and incentives to indirectly control a group of people having communication, e.g., discussion, debate, meeting, and consultation. A communication-field mechanism is expected to give constraints to the actual communications. We hypothesized that such constraints are beneficial for the application of technologies based on artificial intelligence. In this paper, we evaluate this concept by taking an automatic speech recognition system and dealing rights to speak (DRS) as an example of proof of concept. An experiment shows that the simple introduction of DRS improves the performance of speech recognition.
