Question: are m and n voiced consonants?
Answer: As you pronounce a letter, feel the vibration of your vocal cords. If you feel a vibration the consonant is a voiced one. These are the voiced consonants: B, D, G, J, L, M, N, Ng, R, Sz, Th (as in the word "then"), V, W, Y, and Z. ... They're common sounds that are produced by blending the two consonants phonetically.
