Overview

VoiceTra4U is an easy-to-use speech translation app especially suitable for travel-related conversations.              The app consists of 2 modes; ‘Single Mode’ and ‘Chat Mode’. With Single Mode, you may input speech/text and have them translated into the selected language on your device. The Chat Mode allows you to link multiple devices to chat with up to 5 different language speakers, either face-to-face or remotely, and have your speech/text translated into the speakers’ respective languages in real time. The app contributes not only to break the language barriers but modality barriers as well; for instance, communicating with the visually-impaired via speech, or with the hearing-impaired via text.

The app covers over 30 different languages (See the list of Languages). The speech data collected by using this app will be utilized for improving the speech translation technology being developed through U-STAR researches based on the 'Terms of Use'.
The app is available for FREE on the App Store. *Packet data fee is not included.

Limitation of Chat Time

Operation Instructions

When you configure a foreign language as an input language, and tap the question mark, "?" in the lower section of the screen, it shows the instructions in the language you selected. For instance, if you select Chinese (standard) as input language, the instructions are shown in Chinese (standard), while the explanation is in English for other languages.
   


Performance

Q: Some translations are wrong.
A: We developed this application with the aim of performing translation for the travel domain, as follows:

"Where is the restroom?"
It cannot translate incomprehensible utterances, exclusive words, or sentences outside the travel domain into travel conversation.
