How to get a deeper voice

Two things decide how deep you sound: the size of your vocal folds, which puberty settled, and how you use them, which is a habit. You can't change the first by practising. You can change the second, and most people have more low end to use than they think.

How to make your voice deeper: the short version

  1. Find your relaxed low note: a lazy “mm-hmm”, then sigh down to the lowest note that stays clear.
  2. Speak a few notes above that floor, not on it.
  3. Relax your throat with a slow yawn-sigh before you talk.
  4. Add chest resonance: hum, feel the buzz in your chest, keep it as you speak.
  5. Breathe low, slow down, and let statements fall at the end.
  6. Practise five to ten minutes a day and re-test weekly.

Expect a modest change: studies of voice training report one to three semitones. The details are below.

Why most voices sit higher than they need to

Your speaking pitch isn't fixed at one note. You have a range, and where you settle in it depends on tension, breathing, volume and mood. Nerves push it up, so do speaking fast and talking over noise. Many people end up speaking well above the relaxed low end of their range all day. That low end is what you're training towards: not a forced growl below your range, but the bottom of the part that's comfortable.

1. Find your relaxed low note

Say “mm-hmm” the way you would to agree with someone, lazily, without thinking about it. The “hmm” usually lands near your relaxed speaking pitch. Now sigh “ahh” from a comfortable note down to the lowest note that still feels easy and clear. Don't go into a crackle. Use the meter to see both numbers.

Live pitch meter– Hz 

Turn the meter on, say “mm-hmm”, then sigh down to your lowest easy note. Nothing is recorded.

2. Speak a little above that floor, not on it

Speech therapists aim for a speaking pitch a few semitones above the bottom of your range, where the voice is relaxed and carries well. Right on the floor the voice gets creaky and tires quickly. If your lowest easy note is 85 Hz, speaking somewhere around 95 to 105 Hz is a healthy target.

3. Relax the throat first

A tight throat raises pitch. A slow yawn followed by a sigh lowers the larynx and relaxes the muscles around it. Do three or four before you practise, or before a call or a presentation.

4. Add chest resonance (voice resonance)

A voice sounds deeper when it's fuller, not only when it's lower. Hum “mmm” on your low note with a hand on your chest and feel the buzz, then open it into “mmm-ahh” and keep that vibration. Speaking with that fullness makes the same pitch sound deeper.

5. Breathe low, slow down, and finish sentences down

How to speak in a deeper voice day to day

Exercises set the habit; conversations are where it shows. To lower your voice when you talk, take a breath before you start so you don't begin on a squeezed, high note, start your first word near your target, and keep your volume moderate (loudness pulls pitch up). On calls, stand or sit upright with your shoulders down. If you catch your voice climbing, pause, breathe and restart lower. That pause also makes your voice sound lower and more settled to listeners.

6. Practise daily, then measure

Habits change with repetition: five to ten minutes a day works better than an hour once a week. The deep voice exercises are a ready-made routine. Take the free test once a week, at the same time of day, to see whether your speaking pitch is actually moving.

How to deepen your voice naturally, and how much it can change

Everything above is a natural method: no hormones, no gadgets. It works the same way for anyone, including if you're a man trying to deepen your voice, and it changes less than the internet promises. The best evidence comes from voice therapy for trans men, and it shows speaking pitch dropping by roughly one to three semitones, with a darker resonance. For a man who speaks at 130 Hz, two semitones is about 116 Hz: noticeable, but not a different voice. The bigger change is often how relaxed and full the voice sounds. Details and sources are on the science page.
