For that I buy a vocabulary book, or a phrase book. As I read through it, and if I don‘t know a word or understand a sentence, I try to learn it using various methods, and create an Anki card to keep it in memory. Anki is just to retain the word.
On a plus side, you can buy specialized vocab/phrase books, I have one just for onomonopias. Also my beginner vocab books come with recordings from actual native speaker voice actors, which I add to the deck. Much better quality than anything an LLM or speech synthesizers can give you.
