Warning

It is very much recommended to have an Nvidia GPU (GTX 700+ and newer) for speeding up the AI Inference if you speak one of the Languages with higher WER% (Error rates).

Expect to do some testing with model sizes to fit your speed / precision needs.

From my testing the Tiny, base and even small models are usable on CPU. The Small model with a bit of delay added in OBS. Tested on 5600X (8 threads)

Relative speed / size: Large 1x, Medium ~2x, Small ~6x, Base ~16x, Tiny ~32x

Example: RTX 2060 is able to do large-v2 model in real-time with 2 seconds delay.

Notice

I've made this program for my stream and people ended up really liking it so I've decided to share it. I am just a single developer so I don't have the millions of dollars to spend for testing, I was only able to do limited testing. That hasn't stopped me from trying hard to make the best I can in terms of ease of use and performance.

It is still possible you will encounter bugs, if that happens leave feedback on our Discord and I'll try to help you out.
