The Universal Speech Translation Advanced Research Consortium ( is an international research consortium conducting research and development on a network-based speech-to-speech translation (S2ST) system,
with the aim of breaking the language barriers of the world.U-STAR has developed a speech translation app using this network-based S2ST system, "VoiceTra 4U" (for multiple devices), which implements ITU-T standardization protocols, F.745 and H.625.
VoiceTra 4U helps multiple users (up to 5) to communicate in different languages, in real time either face to face or remotely.
The application contributes to overcome the barriers of languages as well as communication modalities. For instance; it helps users to communicate with the visually-impaired via spoken word, or with the hearing-impaired via text input.
This application mainly targets the field of travel-related conversations at airports, hotels, shops, and restaurants. The application covers a total of 27 Asian and World languages ( 30 languages when dialects are included ).
The speech data collected by using this application will be utilized for improving the speech translation technology being developed at U-STAR.
