To my knowledge there are no models specifically trained for JAV --someone earlier in this forum was suggesting to embark on it. In general for Japanese you'd need a large model. The medium model does a decent job to give you a sense of the topic/dialogue but that's it.

Is this a new thing? Never received that warning before:

/usr/local/lib/python3.10/dist-packages/huggingface_hub/utils/_token.py:72: UserWarning: The secret `HF_TOKEN` does not exist in your Colab secrets. To authenticate with the Hugging Face Hub, create a token in your settings tab (https://huggingface.co/settings/tokens), set it as secret in your Google Colab and restart your session. You will be able to reuse this secret in all of your notebooks.

config.json reach 100% but stop there, nothing after. Never had to use HF Token with your collab before.

Version used is v0_6i

Yes, I just received an issue report on Github too. It seems that something got broken in colab environment. Interestingly Google hasn't announced any official upgrades to colab since 18th December, but they have changed the security policy and some other updates, it seems.

I haven't been able to find a workaround for it yet. Will still dig into it.

Here is a quick workaround: version 1.0 (beta)

github.com

GitHub - meizhong986/WhisperJAV

Contribute to meizhong986/WhisperJAV development by creating an account on GitHub.
github.com github.com


The root of the error seems to be a code break caused by the recent Colab upgrade: mayankmalik-colab .
In this beta release I have replaced faster-whisper with stable-ts package. For now, this release does not use the quantised model for faster speed. We have to wait untill the rot cause is solved to go back to that.

I have tested this relase only on a handful of test audios. If you come across any issues please let me know.

Epanding on my previous post, for those who prefer faster whisper (2x speed):

There is a workaround to run 0.6i (faster whisper). The workaround is not the smoothest but it does the job. Follow the gudiline here:

github.com

i encountered issue in 0.6 version · Issue #3 · meizhong986/WhisperJAV

when i converting my audio file this message appeared on last step/process
github.com github.com

Steps:
1. Run the cells (or all cells) once.
2. Select 'tools' (in the menu bar above) --> 'Command palette'.
3. Select 'use fallback runtime version'.
4. Run the cells (or all cells) again.

Note: the fallback environment is supposed to be a temporary solution. The google rep in the colab community says that they're doing their best to keep the environment up longer than usual, but eventually they need to shut it down. I hope by then we will have a robust solution.

Any chance you will add the V3 model
Click to expand...

My assessment so far:
large-v3: do NOT use. Wait for the next update.​
large-v2: use this one for general purpose.​
large-v1: use this one for cross talks and multiple speakers​

I'd wait untill the Whisper main branch is updated with necessary fixes. There are few fixes suggested to reduce V3's wild hallucination but still not ready for the prime time. Even the most robust fixes that have been suggested so far only make the results of V3 to be equal to V2 in quality. So no gain.

It's a pity that V3 has been such a big disappointment. OpenAI estimated that V3 would improve Japanese WER by 18%, but I guess they failed to measure that hallucination got worst by 200% :)

ok thanks much appreciated.

another question: what does "chunk_duration:" do, the default is 4 what does increasing or decreasing it do?

also "I'm going to sleep." is a phases said a lot in error.

Does anybody else experiences timing issues fairly often when using WhisperWithVAD (up to ~30sec sometimes)?

Are you using large-v2 model? And not large-v3 (and of course "large").

Yes, large-v2. Was also using large-v1 and large-v3 but all of them have the same flaw. There seems no apparent reason. Sometimes it is perfectly fine but then completely out of sync. Even retrying does not solve the issue.

V3 requires very different settings than V2 does, so I think VAD should be updated or tweaked to account for the new settings. Something like the calibration being different (0.5 threshold of one model corresponding to 0.55 on the other) would lead to large differences in hallucinations.

I think it is useful to do a basic run that uses the whisper-ctranslate2 / faster-whisper defaults, mostly, and then doing a second run with a lower threshold, a reduced length penalty, and higher repetition penalty.

--repetition_penalty , at least in the ctranslate2 faster whisper, deals well with large-v3 hallucinations. Setting it high to something like 1.5 deals with most of the regular hallucinations where phantom lines are repeated over and over, but there will still be some hallucinations. I also turn down the length_penalty to 0.7, but that is less crucial.

I'm having good luck with setting the vad_threshold low (like 0.2 or 0.3), but using a high --patience or --best_of.

High patience (like, 15 or 20) seems to help with timings as well. Some of the Slave Color entries I did not spend a lot of time editing before get way better first drafts with large-v3, and the file size is smaller and fewer lines. It misses less but has a way better basic interpretation of what is being said in a lot of the series verbal torments.
