Language Resources
Embark: LDS Missionary Language App, a brilliant way to learn, with audio & flashcard features.
Also use the Gospel Library App for audio & text in most languages.
There are also offline translator devices which hear and speak many languages, a terrific learning & travel tool. Click here for a highly rated one.
Interlinear (side by side) Book of Mormon study is most highly recommended, especially once you have an idea for how to pronounce words in the new language.
