Your vocal cords and other physiological factors determine the sound of your voice. Your adult voice sets well by the time you have surpassed puberty. Sometimes, some environmental factors may project your voice in a different way. Some techniques can help you make slight changes to your pitch and volume to bring out your natural voice in the best possible way, although, it is not possible to completely change your voice from high to low or from low to high.

How to Change Your Voice for Real

You can change your real voice by altering the place you pronounce, practicing certain pronouncing methods and imitating your favorite voices. Let's get closer to know more.

1. Shift the Place You Pronounce

People generally speak from the diaphragm, throat and nose. A good balance between them is necessary.

• Diaphragm: Diaphragm is a large band of muscle under your lungs and above the stomach. In order to speak from your diaphragm, first place a hand on your abdomen right below the ribs. As you take a breath to speak, your stomach should blow a little, but not your chest. If your vocal volume is less, then speaking from the diaphragm helps improve resonance.

• Throat: Learn to speak from your throat by pinching your nose and holding a sustained note. This improves your speech by relaxing your throat muscles. If you have a squeaky or screechy voice, relaxed vocal folds can deepen your voice. If you have a nasal speech, diverting the air from your sinuses to your throat helps a lot.

• Nose: How to change your voice? Speak from your nose. Practice inhaling through your mouth and exhaling through your nose. Take 4-5 breaths, hum a little and then speak, keeping your tongue shallow and mouth small. By reopening the nasal pathways, it helps with your stuffy speech which may be caused by a blocked nose during chronic sinus inflammation.

2. Use Some Techniques

Actors/singers learn to keep their voice in good condition because voice is their career. They have proven to us that many techniques do helps to change your voice.

• Lip Thrills: This technique helps you relax your vocal folds and close cords. To do this, blow air through gently closed lips. If you are doing it correctly, the lips should vibrate against each other. Slowly add long and short vowel sounds of various pitches.

• Nay-Nays: This is a very helpful nasal speech practice. For this, you have to pretend that you are taunting someone in a bratty voice by saying "nay-nay". A gentle buzz should be felt in your sinuses as you are practicing this.

• Ahhhs: This technique is for lowering the vocal pitch of those people who have high pitched or squeaky voices. Inhale deeply and exhale slowly saying "ahhh". Try to hold it for as long as you can.

• Oh-Ah-Oohs: How to change your voice? Inhaling and saying "oh-ah-ooh again and again will do. Do a glottal stop and stress on the dipthong of every syllable. Do not pause for long periods. It is a little faster and energetic, and you will feel your vocal cords constrict or close a little.

3. Imitation Works

If you like a particular voice, say that of some actor, try to imitate the voice. You should analyze the voice's pitch, tone, enunciation and cadence. Start the practice by trying to modify your voice to speak in the exact same way as your voice role model. Later you can just apply the parts of the voice you deem to be the best.

How to Disguise Your Voice

Apart from trying to change your real voice, you can also try to disguise it by using various techniques.

1. Muffle Your Voice

Your voice travels in the form of sound waves through different mediums. The same waves transmit through the air differently than those through any other medium like solids or liquids. So, to muffle your voice, place your hand, a handkerchief or other obstacles directly over your mouth as you speak to produce a more dramatic effect. By placing an obstacle in front of your mouth, you force the sound waves through that obstacle and thus change the way how others receive and interpret the sound.

2. Speak in Monotone

Use less emotion while speaking and your voice will sound different. For example, most people, when asking a question, end with a higher intonation. The same question sounds different when spoken in a flat tone. If people tell you that you have a flat voice, then practice speaking with more emotion or enthusiasm. Think carefully before speaking and change your intonation. Start practicing with simple phrases.

3. Hold Your Nose as You Speak

You can learn how to change your voice by holding your nose and blocking your nasal passages. This is a quick and dramatic way to do it. Just grasp your nose from both the sides and close the nostrils. When you speak, air flows naturally through your mouth and your nose. When you block your nose, the amount of air that would have escaped through your nasal passages is restricted and the air gets trapped deeper in your throat and mouth, thereby changing the pressure. This causes your vocal cords to vibrate in a different way and changes the way your voice sounds.

4. Use a Voice Changer

Voice changing devices are available online, costing anything from $25 to $50. Each device works differently so do check the specifications before you buy a device. Most devices are portable and have the ability to change the pitch of your voice in many ways. Read the instructions carefully and learn the right way to use the device. Some of the devices require a pre-recorded message while others can be used to adjust your voice as you speak, transmitting the altered sound through a cell phone or another speaker.
