How we measure voice depth
The depth of a voice is mostly its fundamental frequency — how many times per second your vocal folds vibrate, measured in hertz (Hz). We track it 100 times per second while you speak and report the median, which ignores the odd squeak or growl.
Typical adult men speak around 85–155 Hz and typical adult women around 165–255 Hz. Your percentile compares you with a simple model of adult speaking voices (an equal mix of those two populations), so treat it as a fun estimate rather than a census.
| Average pitch | Depth | Approx. note |
|---|---|---|
| Under 100 Hz | Very deep | below G2 |
| 100–130 Hz | Deep | G2–C3 |
| 130–165 Hz | Medium-low | C3–E3 |
| 165–200 Hz | Medium | E3–G3 |
| 200–240 Hz | Medium-high | G3–B3 |
| Over 240 Hz | High | above B3 |
Can you make your voice deeper?
Pitch is largely set by the length and mass of your vocal folds, so you can't change it much — and pressing your voice down for long periods can cause hoarseness. What you can change is how full and resonant it sounds:
- Relax your throat and jaw — tension raises pitch.
- Breathe from your belly and speak on the out-breath.
- Slow down — slower speech is heard as deeper and calmer.
- Use chest resonance: hum “mmm” and feel the vibration in your chest, then speak from there.

FAQ
What is a deep voice in Hz?
Below about 130 Hz average speaking pitch is generally heard as deep, and below 100 Hz as very deep.
What is the average voice pitch?
Roughly 120 Hz for adult men and 210 Hz for adult women, with wide individual variation.
Why is my result different each time?
Pitch rises when you're tired, nervous, loud or excited. Speak in a relaxed, normal voice for the most representative number.
Is my recording stored?
No. Pitch and loudness are analyzed inside your browser. When a test needs speech-to-text, the clip is sent once to our provider and not saved by us. Shared links contain only your numbers. See the privacy policy.
