There are 2 groups of consonants: Voiced and voiceless. When you pronounce voiced consonants, your throat should vibrate. Put your fingers around your throat (Adam's Apple) and feel your throat vibrate. When you pronounce voiceless consonants, your throat does not vibrate. Only air comes out of your mouth. It's same air that would come out if you blew a birthday candle. There are more voiced consonants than voiceless ones. Compare between voiced and voiceless consonants as follows.
