When you speak, the air from your lungs passes through your vocal cords making them vibrate. These vibrations make the sound you use to talk. The sound of your voice changes as it passes through your throat, mouth, and nose. This makes your voice unique.
Voice problems may affect:
- the pitch of your voice (how high or low your voice is)
- how loud or quiet your voice is
- the quality of your voice (e.g., breathy, rough, strained)
Resonance problems affect the way the voice is shaped by your throat, mouth, and nose (e.g., too much or too little air moving through your nose).
