Why Is the Word “voodoo” Everywhere on Japanese YouTube?

If you've spent some time watching Japanese KZbin video with the automatically generated Japanese subtitles, you may have noticed the word "voodoo" pop up quite a lot. In this video I explain why it happens, and share my voodoo collection.

As a computer nerd, watching the video just to hear that the model is overfitting rather than the fact that a possessed doll is trying to kill me was a bit underwhelming

[@Livakivi]

that's what the doll wants you to think

BLACK SABBATH VOODOO with lyrics Why shouldn't it overfit and repeat things i say and think when everything else does. Why shouldn't it.

Babe wake up, new livakivi video just dropped

[@deathdoor]

How can this random weeb youtuber make a better and easier to understand explanation about a complicated tech topic than most tech dedicated channels? A man of many talents, husband material.

[@oh-noe]

because this guy actually has talent in all the fields necessary to make easy to understand video content. Many tech channels might be knowledgeable in tech, but not knowledgeable in the art of teaching

Dude I'm astonished by your persona : estonian, fluent in english, fluent in japanese, lifter, very good knowledge in AI and tech, great editing skills, the list goes on. Can you write a bibliography or atleast do a video on all of your life, acomplishments and studies? Or a guide how to be so versatile. LOL

[@elude3808]

Yeah, it amazes me!

[@FatherTullys_Temperance]

It's funny that being estonian adds to the astonishment. Still I agree

[@kanaria449]

i remember putting on the automatic subtitles for some random videos and the word "foreign" would pop up when no one was speaking, that used to scare the crap out of me

[@Pc_User_Pro]

mhm, i have seen foreign too

[@VacantMinded]

Always glad to see more videos from you, also Merry Christmas.

Amazing stuff, really like how you tie your seemingly disconnected interests together

Another liva video so soon what a great Christmas present

[@ferryhmm]

Very different kind of video from you, I like to see it. You can explain very well! Also interesting timing, because right now I am actually procrastinating on writing an essay about deep learning lmao

Very impressive! Happy new year!

Thanks for the Christmas present!

[@RobinsonCajas-wx9rh]

Great video!

[@wowmom98lol]

I’ve noticed that all the time on english youtube, youtube does this with the word “foreign”

[@slaetube]

Hope you dont mind me adding onto the countless comments from earlier, but i do legit like how you present your videos on a clear and to the point style. Plus your editing is enough to keep me hooked on the visuals. But yeah I think only once i encountered a "voodoo" when i accidentally or youtube decided to turn on auto captions on my TV once. I do wonder if there's other funny cases of random words in other languages, or even just in general.

[@abdelrahmanyasser4519]

I love the diversity of your content Liva :)

[@ajanaethompson8445]

メリークリスマス! and thanks for another video. Unique video premise but fun nevertheless.

[@Litepaw]

It's the same reason why there's sometimes randomly the word "foreign" in English auto-generated subtitles. I've always thought it's just basically digital noise.

[@AstralDice]

well about that automatically generated subtitle thing: whenever I watch an English video and activate it, I almost ALWAYS get shown the word "foreign". EVERY. SINGLE. TIME.

[@benjaminrogers8875]

Merry Christmas メリークリスマス

[@frenchertoast]

It might also just be similar enough to くる in fast speech that the model can't easily distinguish the words without context

[@Livakivi]

It also happens a ton on just regular whitenoise and stuff

[@jordendarrett1725]

How are you so knowledgeable in so many subjects?? Also Merry Christmas!

[@meelispuvi8541]

Olen alati tahtnud jalad alla võtta ja hakkata Jaapani keelt õppima, kuid alati on miski ette tulnud ja olen jõudnud päris vähe õppida (võibolla olen natta laisk). Alati on tore näha, et keegi teine on suutnud saavutada midagi mida mina pole. 👍

[@dunk.]

man, here i was expecting it to be some internet slang or a soundalike

[@adamkoltai7629]

I don't know what I voodoo with this information.

[@--Paws--]

I think many KZbin videos also get flagged as violating some rule when the video or creator did not. The AI is misinterpreted what has been said and the video gets taken down.

[@nikolaj3988]

Thanks for watching!

[@Pc_User_Pro]

Yeah, I also have seen similar examples with the word "foreign" in English videos, especially on music. That looked pretty weird. Also thanks for such a detailed and good explanation. By the way, I've seen you're from Estonia and I'm from Lithuania, a baltic country, too.

[@feliperamos3322]

hi Liva!

[@Livakivi]

hy

[@user-wv1in4pz2w]

nice theory, but I think the subtitle generation AI is trying to tell us how it works.

[@festiveFurry]

so... I guess liva is a neural network specialist??? I think I remember liva mentioning that he did programming professionally but I didn't know he also had insights on AI and neural networks.. awesome stuff, really nice liva!

[@Livakivi]

I have three other videos related to AI as well, you can check them out: kzbin.info/www/bejne/mHvToYpsnNh_bc0

[@festiveFurry]

ah, thank you liva! while we're here, I'd like to mention how great your influence was on me starting to do japanese, and even tho the techniques I use are rather different in comparison to your techniques, I still thank you for the motivation

[@gotaro69]

Please make a video about the art of polymathy 🙏

Maybe there was just lots of videos in training data that are used to cover field-specific vocab, and maybe NN decided that Hendrix legacy should go on forever

does google use purely neural networks for speech recognition nowadays?

[@Livakivi]

Very likely, yes, might have some custom data processing before feeding it into the model and perhaps correction pipelines on top of that, but I assume its 99% deep learning

Sounds fine to me

[@danijelgasparic3658]

​@@jasonultimate1208 Bro probably thinks that accent = proficiency

[@artum1s_550]

imo livaviki has native level english, with a non standard accent

[@j5679]

From what I can tell, Livakivi's English is near-native or native-equivalent in all aspects but pronunciation. This is the situation that many young, educated Europeans find themselves in because that's where you end up if you get massive amounts of input but don't do any deliberate work (I'm in the same boat). How good (i.e. native-like) your pronunciation is going to be under these circumstances depends on a number of factors, but first and foremost on your native language. For instance, Dutch, Swedish, Danish and Norwegian natives tend to sound better than most Europeans. I agree that Livakivi's pronunciation can give off a false impression of his overall English competency (at least to uninformed listeners) but lets keep in mind that: 1. Improving one's accent is hard work and it's even harder if you don't do it from the get-go. 2. The juice is often not worth the squeeze, especially if you live in your native country. Nothing about any of this is "a shame".
