Скачать или смотреть Battlefield 6 - Change Audio/ Voiceover Language (see description)

While there isn’t an official way yet to have separate text and voice languages in Battlefield 6, you can modify the audio packs to achieve that.

I wanted to have German text and subtitles with the English voiceover, so I did the following:

Switch the language via the EA App or Steam properties to the language you want for the voiceover (in my case, English).

After the automatic download is complete, copy the desired sound files (see steps below).

This step is optional, but I created a new folder on my desktop and, inside it, two subfolders: MP (for Multiplayer) and SP (for Singleplayer). This is purely to avoid mixing up the files.

Copy the voen.toc file from Battlefield 6\Data\Win32\loc into your MP folder.

Copy the voen.toc file from Battlefield 6\Data\Win32\SP\loc into your SP folder.

Rename the copied files to match your desired text language — in my case, German: voen.toc → vode.toc.

Switch the language back via the EA App or Steam properties to the one that you want for thel texts (in my case, German).

After the download is complete, copy your renamed files back into the original folders:

The file from the MP folder goes to Battlefield 6\Data\Win32\loc.
The file from the SP folder goes to Battlefield 6\Data\Win32\SP\loc.

Now your game should have your normal text language and a separate voice language in both singleplayer and multiplayer.
