WhisperX — Automated Transcripts w/ Timestamps and Speaker Tagging
WhisperX: Automatic Speech Recognition with Word-level Timestamps (& Diarization) - m-bain/whisperX
I think a lot of people have heard of OpenAI’s local-friendly Whisper model, but I don’t see enough self-hosters talking about WhisperX, so I’ll hop on the soapbox:
Whisper is extremely good when you have lots of audio with one person talking, but fails hard in a conversational setting with people talking over each other. It’s also hard to sync up transcripts with the original audio.
Enter WhisperX: WhisperX is an improved whisper implementation that automatically tags who is talking, and tags each line of speech with a timestamp.
I’ve found it great for DMing TTRPGs — simply record your session with a conference mic, run a transcript with WhisperX, and pass the output to a long-context LLM for easy session summaries. It’s a great way to avoid slowing down the game by taking notes on minor events and NPCs.
I’ve also used it in a hacky script pipeline to bulk download podcast episodes with yt-dlp, create searchable transcripts, and scrub ads by having an LLM sniff out timestamps to cut with ffmpeg.
Privacy-friendly, modest hardware requirements, and good at what it does. WhisperX, apply directly to the forehead.
Man where was this post when in was DMing? lol.
This is super cool though. Rn I'm doing some film editing work for my friend, and this could probably be useful for subtitles too. Thanks for sharing.

This is genius. Could you appify this and I'll pay you in real or pretend currency as you prefer

Okay that's just crazy. ;)
Probably not that hard to build a simple flask frontend around it.
Automatically processing files in an S3/WebDAV directory would also be useful.
What would be some use cases for WhisperX? I'm struggling to envision how I would use that in a selfhosting/homelabbing environment.
half sarcastic but the overall premise of rigging something in to a local voice assistant, when an arguement starts "Ok nabu record this conversation". then 2 weeks later on another arguement... "OK nabu search our last arguement for the cabinet". Would be like having a court transcriber on call.
I'm personally looking at setting up whisper or whisperx with bazarr, to get subtitles for movies and series that I can't find any to download.
Long videos or voice notes where you're usually just looking for a small snippet.
Now that's an interesting angle. I am a mediocre musician on my best day, but sometimes I incorporate phrases and lyric snippits in a piece. I wonder if I could use WhisperX to find those words or phrases from a stack of songs. For instance, I did a piece that used a line from Jimi Hendrix's 'If 6 were 9' where he says 'I'm the one who's gotta die when it's time for me to die. So let me live my life the way I want to.' I wonder if WhisperX could pick that out of a stack of Jimi Hendrix songs.
Nice. I learned about different applications of whisper because I'm a degenerate.
Can't say I've ever wanted to turn on the subtitles for porn lol
Sometimes in JAV you really just get curious what the fuck is happening.
That is cool! I've been wanting I've wanted to use a model like this but haven't really looked.
Are you self hosting the long context llm, of do what are you using?
Context lengths are what kill a lot of my local llm experiments.

I did a lot of my exploration back when GPT4 128K over API was the only long-context game in town.
I imagine the options are much better these days between Llama 3/4, Deepseek, and Qwen — but haven’t tried them locally myself.
