There are countless numbers of languages and dialects used around the world and overcoming the barriers between them has been a long-held dream for humankind. However over the years, research and studies on Speech-to-speech translation (S2ST) technologies have made it possible to turn this into a clear goal rather than just a dream. It is not an easy task for an individual to establish S2ST systems that cover all topics and languages, however, by connecting ASR, MT, and TTS modules distributed from organizations around the world, we strongly believe that we can establish a global S2ST system that will allow us to free ourselves from these language barriers.



A research collaboration group, known as the A-STAR Consortium, first started out in the Asian regions to develop a network-based S2ST system.
A-STAR initiated in standardizing international communication protocols, especially in the S2ST field, in association with ASTAP and launched "the first Asian network-based speech-to-speech translation system", on July 29th, 2009. The system enabled real-time, location-free, multi-party communication between speakers using different Asian languages, and confirmed the feasibility of network-based S2ST protocol.

In 2010, the standardizing procedures at ASTAP were transferred to ITU-T as A-STAR shifted to U-STAR, transforming not only its name but to a worldwide consortium with the aim of establishing a more global system. The ITU-T Recommendations F.745, and H.625, for network-based S2ST were both published in October, 2010. Find our more about the standardizations:
