Yes! I also can't distinguish these. This audio clearly has what sounds like a "n" sound between the "m" and the vowel.
But maybe the difference is in the vowel? I can't hear this yet. I also struggle with "y" versus "i" though, so I wouldn't be surprised if the key is in the vowel sounds.
Please be sure to review the older Tips and notes about Czech pronunciation and orthography. Or any similar resource.
dě, tě, ně is pronounced ďe, ťe, ňe
di, ti, ni is pronounced ďi, ťi, ňi
bě, pě, vě is pronounced bje, pje, vje
Other combinations hopefully do not appear in modern Czech.
I and Y sound the same but I may change the preceding consonant.
Please do review those materials.
Came up today and Reported: my answer was and I copy it: "Potřebuje mne" and DL said: "You used the wrong word. Potřebuje mě. Meaning: He needs me." When reported there is no alternative "My answer should be accepted...".so I selected the third one, Czech sentence is unnatural or has an error :-(
I say again, the pronunciation is NOT IDENTICAL. The thing you should have reviewed is
what I have written in my long post below
The guide to Czech orthography and pronunciation, NOT the usage of mě, mně and mne.
BOTH MĚ and MNĚ sound the same and both contain the Ň sound (~nye if you want). Only one of these two is grammativally posible here.
MNE sounds different and connot be accepted here. It has the hard N sound, not the soft Ň sound. You will not get far before reviewing the pronunciation and orthography. Alas, I even wrote the main gist in the other long comment on this page. Just read it.
At this moment, we won't accept it, as we find it too confusing to the majority of users, many of them not being native English speakers. It would also require a lot of work - and none of the volunteers who maintain this course are willing to tackle this issue when there are more pressing things to take care of.
I hope I have addressed your questions to your satisfaction. As always, we're happy to see feedback from our users.
