How will Rocky talk in the movie

I was wondering about that. in the book we see rocky is talking in his own language and we only see english because Grace understands him.

I think in the movie Rocky will make some device and stick it to his body or perhaps Grace will help him with that, and the device will translate in real time what's he saying, kind of like google assistant and stephen hawking combo.

i think it's a good way to adapt what happens in the book because it doesn't betray anything, and of course movies have their own rules and you gotta make changes when you adapt.

i don't think simple subtitles would cut it since rocky is literally the soul of the book and is there for a looong time.
