Fwiw korean doesnt have a ‘V’ sound/character at all, and the V/B switch is quite common on Korean words that come from English. For example, “video” in Korean gets written with ㅂ at the start, and sounds more like “bideo”. And the same character is used in the Korean/Hangul version of their written company name.
Yeah, pronounced in korean it definitely is more similar to Biosys than Viosys. But since they have written it as Viosys in all english documentation and websites it is very suspect that the article writer would misspell it like that. So probably AI translating a korean source or something, but AI also does these mistakes much less often these days.
