It's very confusing, and the audio quality is under average. I wanted to contribute, but nobody lets me enter the Incubator :p
If you play the complete sentence you will hear "bah", but if you play only "bea", sounds like "da". Is a software problem, I think. The right form is "bah", makes more sense.
no... it's a clear "b" at the begining...and then followed by the diphthong "ea" ... for a native, it's hard to mistake it for a "da" as in sound
Yes but copil is boy or girl, the aim of the exercise is to insist on that point.
"kid" is not a word many people would use here -- some might even consider it substandard
Formerly ‘bastard’, probably from Proto-Slavickopylъ (“shoot, sprout; bastard”) (compare Ukrainian копил (kopyl) or копиля (kopylja), Serbo-Croatian копиле (kȍpile),Bulgarian ко́пеле (kópele)), from kopàti(“to dig, cultivate”). Also borrowed into Albanian kopil, Byzantine Greek κόπελος (kópelos). Alternatively an old ultimately paleo-Balkan substrate word. Compare Aromanian cochil.
