Help needed making voice typing work in Ubuntu

I've just recently transitioned from Windows to Linux as a lifelong user and I can't for the life of me find a way to type with my voice. Ive tried some scripts and apps but I couldn't make it work after trying for a few days straight.

I mostly need it in Firefox but it'd be nice to have it systemwide.

I'm using ThinkPad Carbon X1 Gen 6 so Whisper AI is out of question as it requires a graphics card.

What could you recommend?
