Typing word and sentence translations from your L1 into a language you don't speak just isn't a good way to learn a language.
I'm often hanging on the (absolutely terrible from a usability perspective) Duolingo forums to help people attempting to learn French and as such I often encounter people complaining that they can't figure out what the voices are saying. As a native speaker I can generally make out what it's supposed to say but it definitely sounds off and artificial. And even when the pronunciation is technically correct it's completely flat and lacks the natural emotion and emphasis a native speaker would use.
The fact that an app who's supposed to teach you languages relies on crappy text-to-speech to teach you pronunciation tells you everything you need to know about Duolingo.
Right now I can comfortably comprehend any A1 text, and can get by with A2 text when I look up the meaning of some words. I'm only halfway through. I can speak enough to at least successfully use speech to text on my phone (I answer textual questions on my phone by speaking and letting it turn my speech to text). I can understand some children shows. I have ONLY worked with Duolingo (and I read Dutch reddit comments). If it weren't for Duolingo I would never stick to it.
