Can I use it to translate 1-2 sentences instantly?
I was imagining real person to person voice contact. Because text based is too slow, and I was imagining this being used with say tourist trying to communicate with natives. The native are not going to wait for them to type it out on their phone, which is so slow, and then wait for someone to respond. For that might as well use Google translate.
Yes, as far as I understand, the developers take as their basis the voice, not the text. Thus, the application is provided in ordinary everyday situations, literally on the move. A kind of pocket translator
