Find a language both of you can use

Check the features for your language.

Full audio is listed for English, Japanese, Portuguese — Brazil, Simplified Chinese and Spanish — Latin America. The other listed languages have interface and subtitle support, with full audio not listed.

Coverage here is from the Steam listing. It is not a promise that console language packs or DLC have identical availability.

All 16 Steam-listed languages.

Pick shared words before the session.

The game's conversation is a separate decision from the language list. Choose a spoken language you can both use, then agree simple words for directions, shapes, colors and positions. The two-way phrase check tests whether you can hear and repeat one another.

If you prefer different written terminology, describe an object's visible features before relying on a name. “The circle above the two lines” is a communication example, not a clue from a verified room. A shared landmark and a repeat-back often prevent two descriptions of the same object being mistaken for different objects.

If either player depends on full game audio in a particular language, check that feature before buying. Do not treat interface-language support as a translation service for your conversation.
