NhaTra speech translation app launched for Vietnamese speakers living or planning to work, study, or undertake practical training in Japan

 In collaboration with FEAT Limited (hereafter FEAT; head office Shinjuku Ward, Tokyo; President: Miyuki Okuyama), Toppan Printing Co., Ltd. (hereafter Toppan Printing; head office: Chiyoda Ward, Tokyo; President & Representative Director: Shingo Kaneko) is conducting research and development of Japan’s first speech translation system for use at local government offices as a part of a five-year (fiscal 2015—2019) research project commissioned by the National Institute of Information and Communications Technology (hereafter NICT; President: Hideyuki Tokuda). 
 One outcome of this research is the provision of NhaTra, a free speech translation app for Vietnamese speakers. The main purposes of the provision of the app are to promote awareness of speech translation of Japanese and Vietnamese and establish environments that support introduction of the technology to local government organizations and other elements of society.
 Before traveling to Japan, Vietnamese speakers can download the NhaTra app onto their smartphone and use it as a tool for learning Japanese. After arriving in Japan, they can familiarize themselves with using the speech translation function as a communication tool for all aspects of everyday life.


 Vietnam has a close relationship with Japan and plays an important role in supporting the Japanese economy. The number of people coming to Japan from Vietnam for sightseeing, work, study, and other purposes is increasing significantly. It is therefore necessary for various sectors in Japan to promptly establish environments that can readily cater to such visitors.
