This feature is already implemented in the current PR. The new CLI option (--word_timestamps) is passed to Whisper as input, and since it's already defined within Whisper, no further changes are needed. I made a fork to implement this and some other pending PRs.

Oh awesome, I thought that perhaps whisper's output format changes so the srt generation needed to change but it does not. Your fork seems great!
