Types of consonants
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 palate to further modify speech.
