Voice And Voiceless Phonetics English Phoneticists , who study the sound of the human voice, divide consonants into two types: voiced and voiceless. Voiced consonants require the use of the vocal cords to produce their signature sounds; voiceless consonants do not. Both types use the breath, lips, teeth, and upper palette to modify speech further. VOICED CONSONANTS Your vocal cords, which are actually mucous membranes, stretch across the larynx at the back of the throat. By tightening and relaxing as you speak, the vocal cords modulate the flow of breath expelled from the lungs.  An easy way to determine whether a consonant is voiced or not is to place a finger on your throat. As you pronounce a letter, feel the vibration of your vocal cords. An easy to test by putting your finger on your throat. 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. But i
