I had never been satisfied with any of the dictation tools available on Linux, until recently where I found an open-source speech to text engine and gives excellent results, however it is just a library (VOSK-SDK).

So I put together a small script that integrates it and makes it a tool that can be used for dictation on the Linux desktop, I use this with a bare bones tiling window manager only activating it when I want to do dictation, so no background processes.

While I realize this probably isn't enough for everyone, for basic dictation (including this post) I find it sufficient.
