Animals make sounds and communicate. Is there a proper name collectively for these sounds?
1 Answer
I think it could be '[動物]{どうぶつ}の[鳴]{な}き[声]{ごえ}'.
There are words for chirp and carol (さえずり), barks ([吠]{ほ}えごえ),etc. but as a collective term for the sound of animals, it is the only phrase I know of.
As for the '動物語', it is what we would likely come up with as a coined word for 'animal language', when we are anthropomorphizing animals playfully.
In fact, the first page of Google search results gives me a link to a toy called [動物語翻訳機]{どうぶつごほんやくき}, among others.
