Currently, on Steam we can search by “Language” but it does not have any option to search by “Language Audio”. Came across this site SteamDB that solves that.
This is really useful for people looking for games that have audio in their target language. There is option to search by subtitles too. You can also exclude english to find game that are only in your target language
Steamdb is a great resource for finding interesting games, just always remember to exclude the hentai and nudity tags or the top results are going to be nothing but porn games.
I mean, some porn games can have quite a lot of text and audio
Human imitating animal sounds is not the same cross-culture and language (e.g. dog barking or frog croaks), so maybe there is an opportunity to learn to moan in different languages /s
