As a result of globalization, information, tourism, and transportation are no longer limited by borders; however, people are still subject to language barriers. VM-FI, Inc., a startup tutored by NCNU, developed a translation system that integrates artificial intelligence (AI) and the 5G high-speed communication technology. VM-Fi has been recognized by the world's most technologically influential "CES 2022 Smart City Innovation Award." VM-Fi uses smart city 5G and AI to provide high-speed, real-time voice interpretation services. With VM-Fi, a speech given by one person on stage can be translated into a different language simultaneously for one hundred audience members, which removes language barriers instantly and achieves the goal of a smart city lifestyle.
