Sentence mining for vocab

So, I don’t have a PC and have been learning for a little (3 months), so I started to think about a good way to sentence mine on aphone without hating it.

I wanted sentences with audio (preferably also get the word audio by itself, but whatever), but it seems pretty annoying to record manually from what I’m watching, and there’s books too.

I would be glad to have some place to download sentences easily so I can have anki card with audio.

So does anyone have some advice?
