I have just started to learn Russian, the difference between "Б" and "П", "Д" and "Т" puzzled me
Could anyone explain the different pronunciation of those letters, in English or in Chinese? To me they just sound very similar( I tried to recognize them on those online listening courses). Thanks!

Question

Answer

Б is voiced, similar to 'b' in 'blue'
П is unvoiced, similar to 'p' in 'plus'
Д is voiced, similar to 'd' in 'done'
Т is unvoiced, similar to 't' in 'tan'
