VoiceTra is a speech translation app that translates your speech into different languages.
VoiceTra supports 31 languages and can be downloaded and used for free. With an easy-to-use interface, you can also check if the translation results are correct.
VoiceTra, whether to enhance your travel experience or to welcome visitors to Japan, will definitely come in handy as your personal speech translator.

VoiceTra utilizes high-precision speech recognition, translation, and speech synthesis technologies developed by the National Institute of Information and Communications Technology (NICT). It translates your spoken words into different languages and outputs the results in a synthesized voice.
The translation direction can be instantly switched; 2 people that speak different languages can communicate using a single device.
Text input is available for languages that do not support speech input.

VoiceTra is best suited for travel-related conversations and is recommended for situations and places such as below:
・Transportation: Bus, train, rent-a-car, taxi, airport, transit
・Shopping: Restaurant, shopping, payment
・Hotel: Check-in, check out, cancellation
・Sightseeing: Overseas travel, serving and supporting foreign customers
*VoiceTra has also been introduced as a disaster-prevention, disaster-related app.

While VoiceTra can be used as a dictionary to look up words, it is recommended to input sentences as it interprets the meaning from the context to output the translation results.

Excellent application

It’s really nice and accurate translation software app I have ever seen. I’m strongly recommend this for your travel companion translation apps. Everyone should have this app in their phone. I really appreciate their hard work and all the afford to this application. I believe they can make a lot of improvement on this and I wish to make a price tag for this application as well to appreciate the hard working of theirs. Overall, it’s the Beat translation apps ever. Worth to use it. I gave 5 stars rating.

Best translation app!

Excellent app bridging the communications gap between cultures. I’ve used this app many times to ask questions, get directions or to learn how to say specific phrases. I’ve tried this, google translate, iTranslate, and All Language Translater, found this to be the most useful app!

You require a data connection in order to utilize the app, but it’s free, accurate and easy to use!

Excellent teacher

This is a great app. It’s really useful for language learning. Please incorporate Romaji for better and clearer understanding for the translated words. I’m learning Japanese. If you find other areas for improvements kindly do so. We love this app and thanks
