VoiceTra is a free application that supports 31 different languages and can be easily downloaded. It is designed to be a personal speech translator, making it a useful tool for travelers or for welcoming visitors to Japan. The app utilizes advanced speech recognition, translation, and synthesis technologies developed by the National Institute of Information and Communications Technology (NICT). This allows users to speak in their native language and have it translated and spoken back to them in a different language.
One of the key features of VoiceTra is its ability to instantly switch translation directions, making it possible for two people speaking different languages to communicate using a single device. In addition to speech input, the app also allows for text input for languages that do not support speech input. This makes it a versatile tool for various situations and places such as transportation, shopping, hotels, and sightseeing.
While VoiceTra can be used as a dictionary, it is recommended to input full sentences as the app interprets the meaning from the context to provide accurate translation results. The app requires an internet connection and may take some time to display results depending on network connectivity. It also supports text input for languages that are supported by the device's keyboard.
It is important to note that some functions or the entire app may be disabled if the server is down. Users are responsible for any communication fees incurred while using the app, and international data roaming charges can be expensive. The app was developed for research purposes and uses servers that are also set up for research. The data collected from users will be used to improve speech translation technologies.
While businesses can test out the app, it is recommended to use private services that have licensed the technology for continuous use. For further details, users can refer to the "Terms of Use" on the app's website. With its wide range of supported languages and advanced technologies, VoiceTra is a convenient and useful tool for anyone looking to communicate in different languages.
