What's unique about this launch is the idea that can be applied to any other pairs of languages for translation. You simply speak into microphone in any of the two languages (in this case English or Vietnamese). The program will decide if you spoke in Vietnamese or English (You do not have to choose). It then reads out what it thinks you said and speech out translation in the other language. This allows users to confirm if it's what they're to say before passing the microphone to the other user.
