Japan’s biggest mobile carrier NTT Docomo has developed a real-time Japanese ↔ English translation service for mobile phones, the first of its kind. The way it works is that you speak something into the device and wait to hear a voice interpretation of what you just said in another language.As you can see in the videos embedded below, the service, which uses the cloud for the heavy lifting, isn’t quite “real-time” but pretty close. NTT Docomo says the service can be used for communicating over the phone but also face-to-face.
