Whisper has been great for me. I have a single-file uv powered python script that creates SRT files or timestamped text files from media stored on the filesystem. https://github.com/danielhoherd/pub-bin/blob/main/whisper-tr...

Whisper?

Whisper large v3 turbo if need support of many languages and want fast enough for deployment even on smartphones (WhisperKit). Can also try lite whisper on HF if need even smaller weights and slightly faster speed.
