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. ■Features: 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, allowing 2 people that speak different languages to 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. ■Supported languages: Japanese, English, Chinese (simplified), Chinese (traditional), Korean, Thai, French, Indonesian, Vietnamese, Spanish, Myanmar, Arabic, Italian, Ukrainian, Urdu, Dutch, Khmer, Sinhala, Danish, German, Turkish, Nepali, Hungarian, Hindi, Filipino, Polish, Portuguese, Brazilian Portuguese, Malay, Mongolian, Lao, and Russian ■Restrictions, etc.: Internet connection is required. It may take a while to display the translation results depending on the network connectivity. Languages available for text input are those that the OS keyboard supports. The characters may not be displayed properly if the appropriate font is not installed on your device. Please note that some of the functions or the application itself may be disabled when the server is down. Users are responsible for the communication fees incurred to use the application. Please be aware that international data roaming charges can be expensive. This application was developed for research purposes; targeting individuals to test it out when traveling, and uses servers that are also setup for research purposes. The data recorded on the server will be utilized to make improvements in speech translation technologies. You may test out the app for businesses, etc., but please consider using private services that we have licensed our technology to for continuous use.

翻訳のニュアンスが完璧です。 長文でも難なく翻訳されます。 翻訳アプリを8個試して、一番性能が良かったです。

ビッグデータの統計によると、すべてのiphone携帯電話ユーザーの中で、iPhone13携帯電話を使用する割合が最も高く、18%に達しました!一方、iphone13の初期システムはiOS15です!そのため、VoiceTraもiOS15のiPhone13をサポートすべきだと思います。

日本總務省所屬的國立研究開發法人情報通信研究機構開發的免費無廣告翻譯app,雖然介面較為簡陋,但是針對日文翻譯的精準度相較apple及google翻譯高很多

他のアプリは使用したことがないため比較はできませんが、実際に外国人(英語圏以外でも)との会話、意思疎通に困りませんでした。

I live in Japan and cannot speak, read, or write Japanese yet. I am able to survive here using this translator. It recognizes when a Japanese word is a city, prefecture, or train station and does not try to translate that with a ridiculous English word. I have been to many ward offices and the Japanese staff there use this app too, when dealing with foreigners.

Tried multiple times (Cantonese to English & Cantonese to Japanese). NOTHNG is correct, not even close to what I said. Garbage app.
