About this app

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.

・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.

Am impressed with the results, especially for short & clear sentences. I've done a quick comparison for several language pairs (English to & from Japanese, Spanish, French and Dutch) with Google Translate and found VoiceTra to be more accurate across the board and generally easier to understand. Too bad speech input is not (yet?) available for all the languages listed. I assume, and hope, that's because it's still a work in progress…

good translation, no ads, big fonts and the app keep listening till you press stop so, unlike those apps that automatically stop listening if they don't sense anything within a few seconds, it's suitable for translations with long pauses between one sentence and the next.

Was great initially but the app won't connect to my network anymore and hence useless. Everything else I have connects with no issues. I uninstalled and reinstalled, checked permissions, checked settings but same problem. This was the only app that accurately translated Burmese when it was working.
