(Well, I hope Duolingo supports RTL texts because the exclamation mark might appear at the beginning on an Arabic sentence)
Hm.. so how does one say "amazing Duo"? Isn't that "دُوو مُمتاز." as well?
The TTS speech isn't that great in distinguishing consonants and vowels. و can be a long vowel u and a consonant w but the TTS speech pronounce it as Duuu instead of Duwuu.
Could anyone explain the spelling of دُوو as "Duo". I know that dammah+waw=long "u", but what would be the pronunciation of this word without the dammah? Why is not enough just only dammah without the first "waw" as short "u"? What does indicate in this spelling that the last letter "waw" is read as a vowel and not as a consonant?
DL also accepts "excellent" as another meaning for مُمتاز . That is good because "مُمتاز " is the very word the teacher will write on your paper when you get all the answers right!
