I reported that the fast version sounds like she's saying "Es abrigo." It's only when you listen to the slow version that it sounds right. This was reported 2 months ago by someone else in the comments. Does Duo ever do anything about these reports? I've seen so many complaints about the female voice and that she doesn't sound right on many questions. Hola duo ¿Estas escuchando?
I need help!!!! When do you use ese, eso, este, esto? What are the difference between the words?
You may have too much of an English accent. They're testing for how close you can get to how a native speaker would talk. I've heard people speak "spanish" with all the right words, but with a thick American Southern drawl. No one in Mexico could understand them and they blamed the Mexicans! Duo is trying not to produce that kind of speaker. Spanish is very enunciated compared to English. We have lazy vowels in English, but in Spanish they are very crisp.
