Same happened to me with English: I've got "Thanks for watching" many times.

Super annoying when it happens with voice chat -- it'll just be explaining something and suddenly stop to say "you're welcome! Feel free to come back any time you want to chat" and that conversation is done.

Since it says "Translated by Nancy Qanqar" i'd be willing to bet they're training on some audiobooks with a transcript and somewhere in there it consistently has "Translated by Nancy Qanqar" in the transcript where there is dead air in the audiobook.

Earlier quoted context omitted.

In Chinese, it always added something like "For study/research purpose only. Please delete after 48 hours." This is what those volunteers added in subtitles of (pirated) movies/shows.

That is not the case here - I never encountered this with whisper-large-v3 or similar ASR models. Part of the reason, I guess, is that those subs are burnt into the movie, which makes them hard to extract. Standalone subs need the corresponding video resource to match the audio and text. So nothing is better than YouTube videos which are already aligned.

At least for English, those "fansubs" aren't typically burnt into the movie*, but ride along in the video container (MP4/MKV) as subtitle streams. They can typically be extracted as SRT files (plain text with sentence level timestamps).

*Although it used to be more common for AVI files in the olden days.

It's absolutely insane that these companies can't be held liable for what is obvious piracy.

What's insane is copyright. How come you can own intellectual property but not pay a property tax? The ecosystem would be much healthier if to get copyright protections you should declare value of your IP (that you are obligated to sell for if the buyer pops up) and pay tax on this for every year you hold the IP.

Can you imagine if we evaluated property taxes this way? Yeah, nice single family home, better hope nobody offers you the same amount you paid for it or it's back to apartment living for you and your kids.

Your definition is one, but the one the OP is using is overfitting to training data.

That’s exactly my point: by that definition any incorrect answer can be explained by “overfitting to training data”. Where do you draw the line between “overfitting to training data” and “incorrect data” ?

> That’s exactly my point: by that definition any incorrect answer can be explained by “overfitting to training data”.

Not really, getting 94381294*123=... wrong, but close within the actual answer, cannot be overfitting since it wasn't in the training data.

Indeed, with another model I would get persistent transcriptions of silent parts into 'Thanks for watching!' or '[MUSIC]'. Pretty dumb that this failure mode wasn't caught in some QA process, and there are now multiple transcription models suffering from the same issue. Having silent parts in your input audio seems like it should be a very common occurrence...

whisper MUST be combined with silence detection / VAD

If that's truly the case then they should make it part of the product, IMHO.

The same happens with whisper-large-v3 on Chinese transcription: silence is transcribed to something like "please upvote, share and favourite this video". I suspect they trained the model on some random YouTube video without carefully picking really useful data.

lmao

How is this overfitting, rather than a data quality / classification issue?

ُThe Arabic text is the translator's self credit "Translated by Nancy Qanfar"

I know it’s off topic, but it reminded me that translators like to put in Easter eggs, or at least they used to: https://learn.microsoft.com/en-us/archive/blogs/ericfitz/i-a...
