No actors, no script -- just Bryan talking to his own PC, an RTX 3070, which is why it's this fast.

Automatic language detection is back: switch languages between dictations.
Mixing languages in one recording can cause errors. A fixed language can
improve accuracy, especially on short clips.
How it works
The speech recognition runs on your own computer using Whisper. Your voice is never uploaded. You can pull out the network cable and it still works.

How it compares
