Relax the muscles in your face, throat, shoulders and neck. If these muscles are tense, your voice is more likely to have a higher pitch.
Breathe slowly and deeply. Focus on tightening your abdominal muscles gently as you exhale. These muscles help to support and strengthen your vocal tone.
Tilt your chin toward your chest slightly. If you jut out your chin, your vocal chords cannot vibrate as well, which raises your pitch.
Speak, hum and sing in a deep voice several times daily. Don't strain your voice or try to vocalize too loudly. Gently speak, hum or sing for three to five minutes at a time at first, building the length of vocalizations as your voice becomes stronger.
Record yourself reading a passage from a book or magazine. Use your normal voice. Listen for instances when you may be unconsciously using a higher-pitched voice. Record your voice again while focusing on reading at a slower pace and with a deeper tone. Listen to the second recording to notice the improvements.
Drink at least eight 8-ounce glasses of water each day. Avoid smoking and limit your alcohol intake. Staying hydrated is crucial to maintaining vocal health. If your throat is too dry, your voice can sound squeaky, high-pitched and raspy.
