The letters c and g represent velar plosive consonants, respectively voiceless and voiced.
The sounds of c and g are:
c: cat, close, cut;
g: game, get, go.
The consonants c and g are called velar. The sound of c and g are produced when the tip of the tongue is pressed against the soft palate, forming a barrier. They are plosive consonants because when the stream of air breaks that barrier where the air could not escape, the sound is produced.
- c is voiceless, so the vocal cords do not vibrate during the articulation of the consonant;
- g is voiced, so the vocal cords vibrate during the articulation of the consonant.
