I use duolingo and have for 6 years now. The pronunciations are awful on duolingo. What's especially bad is when you have a word and it's pronounced one way in one sentence and another way in another sentence.
And no, i cannot speak any language past just a little bit. I cannot read things in the languages i've been learning and i especially cannot understand them when spoken. And i've worked hard to learn them. That may just be because i'm a slow learner and not duolingo at all.
It's hard learning a language and then not use it. I keep forgetting what i learned.
I would recommend duolingo, but also would recommend using what you learned by reading and listening to materials in that language.

That's not a great testimonial for duolingo if you've been using it for six years and haven't learned any other languages lol
