Thanks. I'm very impressed with Futo. Seems very accurate for me so far. I couldn't work out why it needed the network permission so I just declined it and it still works perfectly fine.
I use transcribro daily, and it consistently surprises me with its accuracy; I had to say "OIC," and I thought for sure it was gonna interpret it as "Oh, I see," but it got it right!
Edit: I just tried FUTO though and I think I already like it better lol
Thanks. I have tried Transcribo as a lot of people say it is very accurate. This isn't the case for me though. Maybe I have a weird accent or something.
You might be interested in Whisper Cpp, there is even an "example" android app in the repo.
If you are looking for complete solution/app, I would probably look into apps that incorporate this lib.
