The audio is a bit weird, because it sounds like "Ei suntă doi frați". It's true that "t" and "d" don't really work together in normal speech, but either you have a small "î" between them (kinda like when you name letters), or the "t" kinda drops. At any rate, nobody will ever put an "ă" between them.

Could it mean "they are two siblings"? Thanks in advance.
