voiceio vs other dictation tools
voiceio is free, open-source voice dictation for Linux. It decodes speech on your own computer, streams a live preview into the focused app, and can fine-tune its model on your own voice. Here is how it compares with other dictation tools, with sources for every claim. Several are excellent on platforms voiceio does not support; we say so.

Free and MIT licensed. Install it with pipx on Linux, or try the dictation in your browser first: the demo on the home page runs a small speech model inside the tab.
