5 stars? Well, it's one of a kind :D And it does a pretty good job but that heavily depends on the circumstances (chosen model, speaker, language, background noise etc).

And it's a good start for automated subtitling:

vosk-transcriber -n vosk-model-en-us-0.42-gigaspeech -i input.mkv -t srt -o output.srt

NB: It's not perfect, YMMV!

PS: You can have also a lot of fun if chose the wrong language ;)
