A deeper voice never fails to grab attention. That’s one reason why voice artists, anchors, and podcasters with a deeper voice attract most voicing projects. Besides the professional realm, people with a low-pitched, deep voice are also good at making better emotional connections in their personal lives.

So, what’s the secret sauce behind developing a deep voice? Is it possible to get a deeper voice naturally? Let’s find out!

How is the Human Voice Generated?

Before we learn how to get a deeper voice, it is essential to know how it is generated.

The human voice is generated through the lungs and larynx. The larynx, also known as the voice box, is the organ responsible for voice production. However, several parts of the body play a role in voice generation.

The voice box or larynx is positioned between the base of the tongue and the top of the passageway to the lungs. When not speaking, the vocal fold remains open for effortless breathing. When we speak, the voice is generated through the airflow from the lungs.

When we try to speak, the pressure below the larynx increases until the vocal folds are blown apart. During this constant opening and closure of vocal folds, the air passes through them at a high speed, leading to vibration. This vibration generates a human voice.

But are voice and speech the same thing?
Definitely no!

What is the difference between voice and speech?

So, what’s the difference between voice and speech? A person crying or laughing is an example of voice production. On the other hand, when people express their thoughts and ideas to one another through a series of complex vocal movements. These vocal movements alter our voice into specific identifiable sounds (words) that form a speech.

Now, the question is, what makes a human voice deeper during speaking?

What Makes a Human Voice Deeper

The voice generation process plays a major role in how deep a voice sounds during a speech. The frequency at which the vocal cords vibrate impacts the depth of a voice. The lower the frequency vibration, the deeper the human voice will be.
Herein are some natural factors that impact the depth of the human voice:

  1. Size of Larynx: A larger larynx (voice box) provides more space for resonance, contributing to a deeper voice.
  2. Vocal cords anatomy: When we speak of vocal cords anatomy, it sums up the size and tension of the vocal cords. The vocal cords with a larger and thicker size tend to vibrate at a lower frequency, resulting in a deeper voice. This is a major reason why men generally have deeper voices than women. Speaking of tension, looser vocal cords vibrate slower, making a voice deeper.
  3. Hormones: Testosterone, also known as the male sex hormone, impacts voice depth. Although this hormone is found in males and females, its levels are higher in males. During puberty, the rise in testosterone levels in males thickens and lengthens vocal cords, significantly deepening male voices.
  4. Airflow pressure: The amount and intensity at which airflow passes through the vocal cords while you speak also affect voice depth.
  5. Resonance Chambers: The size and shape of a person’s mouth, throat, and nasal passages influence the way sound resonates, contributing to the perceived depth of the voice.
  6. Age: Age has a strong connection with the depth of your voice. As stated above, at puberty, vocal cords thicken in males, leading to a deeper voice. Similarly, they may lose elasticity with aging, affecting the depth of voice in both men and women.
  7. Lifestyle and health: Health conditions that impact the respiratory system can influence airflow and voice production. Lifestyle changes like vocal straining, smoking, and lack of sleep can also affect voice depth.

How to Deepen Your Voice Naturally

One simple way to deepen your voice is to maintain a lower speech speed while speaking in your full voice. To achieve this, learn to gain control over your voice through vocal exercises. Vocal or singing exercises can help you brush up your voice. They can strengthen your vocal cords and help you develop control over your voice. You can go with exercises like:

  1. Humming: Warm up your vocal cords and practice accessing lower registers by humming at gradually descending pitches.
  2. Lip Trills: Create a buzzing sound with your lips and slowly descend in pitch. This helps loosen the vocal cords and builds control.
  3. Tongue stretch: Pull out your tongue and move it up, down, left, and right to make yourself more articulate during speech.

Remember, deepening your voice naturally requires time and consistent effort. While deepening your voice is still achievable through constant practice and training, let’s check whether you can change your voice naturally. 

How to Change Your Voice Naturally

While there is no foolproof way to change your voice naturally, you can still try changing it with a combination of exercise and lifestyle changes. 

How to change your voice naturally
  1. Voice control: Controlling your voice pitch can be a great way of instantly changing your voice. Try speaking at different pitches and see what gives your voice more depth.
  2. Maintaining good posture: Good posture will open up your diaphragm and maximize airflow. So stand tall with shoulders back and chin slightly up.
  3. Hydration: Staying hydrated will keep your vocal cords supple and promote a smoother, richer sound. You can also drink lukewarm water in the morning or use it for gargling. In both ways, the idea is to relax your throat and vocal cords.
  4. Diaphragmatic breathing: Breathing from your diaphragm provides greater airflow support and control, contributing to a deeper, more powerful voice.
  5. Voice resting: If you are someone who needs to do a lot of talking, consider resting your voice at frequent intervals. 
  6. Voice training: Vocal or voice training is another effective way to get a deeper voice naturally. You can hire a vocal coach to help you identify your unique vocal strengths and weaknesses.
    He can develop a personalized practice routine and teach you advanced techniques, such as vocal placement and projection, to enhance the depth and power of your voice.

How to Deepen Your Voice With Exercises

The whole purpose of performing vocal exercises is to train your voice. Just like athletes warm up muscles, vocal exercises warm up the vocal cords and associated muscles. Let’s move on to exercises that can influence the quality and pitch of your voice and help you deepen it.

Warmup Exercises

  1. Warmup Diaphragmatic laughter: Warming up your diaphragm will help support your breath and help you speak at a higher pitch without compromising on depth. Start by placing one hand on your stomach and the other on your chest. Take a deep breath and let out a hearty laugh that comes deep from the diaphragm.
  2. Tongue Twister Warmup: A tongue twister is a fun warmup that will help you exercise tongue control. You can start with any tongue-twisting sentence or phrase.
    For example, “She sells seashells by the seashore” or “Peter Piper picked a peck of pickled peppers.” Go with the one you like and repeat it ten times without fumbling. 

Voice Deepening Exercises

Once you finish warmup exercises, it’s time for the actual drill. 

  1. Pitch Slides: Take a deep breath and start on a high-pitched hum (like a yawn). Slowly slide your pitch down to a comfortable lower range, maintaining a smooth, connected sound. Inhale again and repeat, this time focusing on reaching an even lower pitch at the bottom. Do 3-5 repetitions, focusing on control over your pitch.
  1. Yawn Sigh Technique: The yawn sigh technique strengthens your jaw and throat. To perform it, open your mouth silently. Stretch it wide as if yawning, and feel your jaw and throat stretch. Exhale slowly through your mouth, making a gentle sighing sound. Focus on letting go of any tension in your throat. Make sure to repeat this process for 5-10 repetitions.
  2. Neck Muscle Stretching: To stretch neck muscle, tilt your head to one side, bringing your ear towards your shoulder. Hold this stretch for 15-20 seconds, feeling the gentle pull on the side of your neck. Repeat the same process on the other side.
  3. Tonal Drills Warmup: To perform a tonal drill, choose a vowel sound, like “ah,” “oo,” or “ee.” Sustain the vowel sound on a comfortable pitch for a few seconds. Experiment by slowly sliding your pitch up and down while maintaining the vowel sound. Also, try changing your loudness while holding the vowel sound to experience voice depth.
