I was wondering... Is there any differentiation between 'turtle' and 'tortoise' in greek? Both translations are accepted for 'χελώνα' in this exercise
I wish fixing things was as easy as saying: "Just fix it." but that would entail a major alteration to the computer program. The audio here is TTS and believe it or not the best that can be found.
We agree that some areas are not as clear as they might be but teaching through an internet program does encounter such problems. I find the general pronunciation far superior to others I've heard...even some human programs.
I should also point out that the contributors and moderators who are involved in creating the course have no way to alter the computer. If you like please report this to Duolingo directly:
In Modern Greek, the letter "χ" has two sounds: Before /e/ or /i/, it is pronounced as [ç], similar to the "ch" in German "ich", "wirklich", etc.; Before /a/, /o/, /u/, or consonants, it is pronounced as [x], similar to the "j" in Spanish "jamás", "carcajada", the "ch" in German "Buch", "Tochter", Scottish "loch", etc.
In Ancient Greek, "χ" was pronounced as an aspirated /kʰ/.
