It reportedly has the capability to translate languages in real-time during voice calls, video calls, and face-to-face. The feature is said to be better than language translation on Google’s Pixel Buds as the former doesn’t require an active internet connection.
No, but it’s a hell of a lot easier to put huge language datasets into the machine learning blender and get a model out, instead of manually programming every conceivable linguistic construction.
Oh and it likely has to do speech-to-text first, another good fit for machine learning models.
