Lot's of audio's has been recently re-uploaded and the pronunciation of the written words in Arabic are WRONG. be careful. I guess duo won't fix it! but i hope members see it and not compromise the sounds, because for a beginner they get very confusing and you end up learning the alphabet wrongfully!
im just starting arabic so dont know enough about right or wrong but when the male voice who sounds kinda young gives a letter(s), it isn't very clear especially compared to the female voice.
i think it was a letter with a short a ? i dont remember. i remember i was more looking at the text and letters than paying attention to short unclear audio for help in finishing the task.
If you are interested and fluent enough you could sign up as a contributer? Though only if you are fluent. Are you sure it's incorrect rather than a dialect difference though? Think of someone from the Southern USA vs Northern Ireland vs New Zealand, they are all using totally different vowels, but i don't think any of them are doing it "wrong"? I think Arabic is at least that diverse, if not more? https://incubator.duolingo.com/apply
