Voice Hz Test
Measure your voice frequency in Hertz — see your live Hz, nearest note, and highest/lowest vocal range. Free, browser-based, no download.
Enter Hz manually
No microphone? Type your voice frequency in Hz to see your voice type and nearest note.
How to Test Your Voice Hz
- Allow microphone access when prompted.
- Sing or speak at a normal volume — the live Hz updates in real time.
- Read the Hz value next to the nearest note name and cents offset.
- Check Highest / Lowest below the meter for your session's Hz range.
What Is a Voice Hz Test?
A voice Hz test measures the fundamental frequency (F0) of your voice in Hertz — the number of times your vocal folds vibrate each second. It is the same measurement that distinguishes a deep voice from a high one, and it is the acoustic building block of pitch.
This tool estimates your frequency in real time using the scientifically validated YIN algorithm and shows it as a live number in Hz, alongside the nearest musical note. It also tracks the highest and lowest Hz you hit during a session, so you can see your vocal range at a glance.

Voice Frequency (Hz) Reference
Here are the typical speaking-voice ranges by voice type, using the same thresholds as our Voice Frequency Analyzer. In practice, most adult men speak around 85–180 Hz and most adult women around 165–255 Hz.
Voice Hz vs. Pitch: What's the Difference?
Hz is the physical measurement — how many times your vocal folds vibrate each second. Pitch is how your brain perceives that frequency. The relationship is logarithmic: every octave up doubles the frequency. A4 is 440 Hz, A5 is 880 Hz, and A3 is 220 Hz. That is why a voice at 200 Hz sounds much closer to 180 Hz than the raw numbers suggest.

Frequently Asked Questions
A voice Hz test measures the fundamental frequency (F0) of your voice in Hertz (Hz) — how many times your vocal folds vibrate each second. Sing or speak into your microphone and see your live Hz reading, nearest note, and session's highest/lowest Hz.
Open this page, allow microphone access, and sing or speak. The display updates your current frequency in Hz several times per second, all processed locally in your browser — no audio is uploaded.
A typical adult male speaking voice is around 85–180 Hz (median ~110–130 Hz); an adult female voice is around 165–255 Hz (median ~200–220 Hz). Singing extends both higher and lower.
Hz is the physical measurement — vocal-fold vibrations per second. Pitch is how your brain perceives that frequency. The relationship is logarithmic: each octave doubles the frequency (A4 = 440 Hz, A5 = 880 Hz).
Yes. This voice Hz test works on any modern phone browser using the device microphone. Allow access and speak — the Hz readout works the same as on desktop.
Your voice naturally fluctuates in frequency, and vibrato or background noise can shift the value. The confidence indicator shows detection stability. Sing or speak steadily and move closer to the mic for a steadier reading.
