In this paper, we proposed an information support system based on a crowdsourcing model, in which multiple workers
cooperated to help realize smooth communication between people with or without difficulty in hearing. More speci-cally, we proposed a crowdsourced captioning system that converted sign language to text in real-time. Our system enabled deaf and hard-of-hearing people, who were generally considered as the beneciaries of information support, to become the ones who offered the support to others.
