The Technology Enabling Japanese Creators to Communicate with Global Audiences!

CoeFont is revolutionizing communication again by utilizing AI technology to convert Japanese recorded voices into AI voices capable of speaking other languages. A survey conducted by Duolingo, Inc. in December 2020 found that 70% of Japanese people struggle with English, indicating a significant psychological barrier to learning and communicating in the language. In addition, learning any foreign language requires a considerable investment of money and time, creating an additional barrier to multilingualism and intercultural communication in Japan.

With Cross-Lingual TTS, users can effortlessly speak multiple languages by simply recording in their native tongue. This technology allows individuals to speak fluently in languages such as English and Chinese using their own AI-generated voice, making multilingual communication more accessible and affordable. The service will enable Japanese-speaking creators to reach a global audience without the need to hire voice actors or narrators fluent in multiple languages. A waitlist has been created for those interested in signing up for the beta service. The service will be made available to registered users in the near future.

CoeFont continues to develop and implement communication strategies that transcend language barriers and enhance accessibility with AI technology.
