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, Tamil, Danish, German, Turkish, Nepali, Hungarian, Hindi, Filipino, Bengali, 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.
