The international language packs for Xbox One and PlayStation 4 should download automatically as game patches, but the non-English languages for Nintendo Switch are available as Free DLC. Here's how to find the International Language Pack for your Nintendo Switch:
- Make sure your Nintendo Switch is connected to the internet
- Launch the eShop from your Nintendo Switch HOME Menu
- In the search bar, enter the game name (either Baldur's Gate I & II: Enhanced Edition or Planescape: Torment and Icewind Dale: Enhanced Edition)
- Select the game from the search results
- Scroll down on the eShop store page; you should see the International Voice Pack
- Select the International Voice Pack and follow the onscreen instructions to download the content
