Find out the frequency of your voice in hertz (Hz). This free voice Hz test listens through your microphone while you read a short passage or hold one steady note, then shows your median and average voice frequency, your typical pitch range, the nearest musical note and how steady your pitch was. It takes about 15 seconds and runs entirely in your browser.
Voice Hz Test
Measure your voice frequency in Hz with your microphone. Read a short passage to find your speaking frequency, or hold a steady “ah” to see the exact note you're producing.
Read aloud at your normal pitch: On Saturday morning we walked along the river to the old market. The stalls were full of fresh bread, bright flowers and baskets of ripe fruit, and everyone seemed to be in a good mood.
Sing or say “ah” at a comfortable pitch and hold it steadily. Press Stop when you're done.

How to Take the Voice Hz Test
- Choose Speaking voice to measure how you normally talk, or Steady note to measure one sustained sound.
- Press Start test and allow microphone access.
- For the speaking test, read the passage aloud at your usual pitch and pace. It stops by itself after 15 seconds. For a steady note, say or sing “ah” and press Stop when you’re done.
- Read your results: the median frequency is the headline number. Press Copy result to save them.
Speak as you normally would. Pushing your voice lower or higher than usual measures the effort, not your natural voice. No microphone? Use the converter under the tool to turn any frequency into a note.
What Is Voice Frequency?
When you speak or sing, your vocal folds open and close many times a second. The number of vibrations per second is your fundamental frequency (F0), measured in hertz. A voice at 120 Hz vibrates 120 times a second. Lower numbers sound deeper, and higher numbers sound higher. Your voice also contains overtones (harmonics) at multiples of that frequency, which give it its tone, but pitch is set by the fundamental.
Speech moves up and down all the time, so a single reading isn’t meaningful. That’s why the test reports the median, the middle of all the readings in your sample. It isn’t thrown off by a brief squeak or a creaky low word.
Average Voice Frequency for Men, Women and Children
| Speaker | Typical speaking frequency | Nearby notes |
|---|---|---|
| Adult men | about 90–155 Hz | around F♯2–D♯3 |
| Adult women | about 165–255 Hz | around E3–C4 |
| Children | higher, often 250 Hz and above | around B3 and up |
The adult figures are the typical ranges for voiced speech given in voice-science references (Baken, Clinical Measurement of Speech and Voice). Many healthy voices fall outside them. They are averages, not rules, and your frequency says nothing about your gender, age or personality. Your singing voice covers a much wider span: from about 82 Hz (E2) for a bass up to 1,000 Hz or more for a soprano.
Understanding Your Results
- Median frequency: your typical pitch, and the best single number to compare over time.
- Average frequency: the mean of all readings. It sits close to the median unless your pitch varied a lot.
- Typical range (middle 80%): how high and low your voice moved during the sample, ignoring the extremes.
- Lowest / highest stable: the lowest and highest pitches you held briefly and steadily.
- Nearest note: the musical note closest to your median, for example 131 Hz ≈ C3.
- Pitch variation: how much your pitch moved. Expressive speech varies more; a steady sung note varies very little.
- Reference scale: your median marked against the typical adult speaking ranges.
Voice Frequency and Musical Notes
Every musical note has a fixed frequency (with A4 = 440 Hz), and each octave doubles it. These are common landmarks for the human voice:
| Note | Frequency | Where it sits |
|---|---|---|
| E2 | 82.4 Hz | Low note for a bass voice |
| A2 | 110 Hz | Typical low-to-mid adult male speech |
| C3 | 130.8 Hz | Upper end of many men’s speaking voices |
| G3 | 196 Hz | Typical adult female speech |
| C4 (middle C) | 261.6 Hz | Upper female speech; children’s speech |
| A4 | 440 Hz | Standard tuning note; mid-range singing for women |
For the note and cents of each sung note in real time, use the pitch detector. To convert any number, try the frequency finder.
How Deep Is My Voice?
A lower median frequency means a deeper-sounding voice: under about 100 Hz is very deep for speech, and around 100–130 Hz is deep. How deep a voice sounds also depends on resonance, loudness and speaking style, not just Hz. For the lowest notes you can actually sing, take the deep voice test. Don’t force your voice lower to change the result: that strains the voice and mostly adds creaky vocal fry.
Why Your Voice Frequency Changes
- Time of day: voices are often slightly lower in the morning and rise as you use them.
- Emotion and energy: excitement and stress raise the pitch; calm, tired speech is lower.
- Volume: speaking louder usually raises the pitch.
- Colds and a hoarse voice: swollen vocal folds vibrate more slowly, so the frequency drops.
- Age: voices change most in puberty; smaller changes follow over the decades.
To compare results, test at the same time of day, with the same passage and microphone distance.
Tips for an Accurate Voice Hz Reading
- Use a quiet room, with the TV, music and fans off.
- Hold the phone or microphone at arm’s length, and keep that distance the same.
- Read at a normal speaking volume. Whispers and breathy speech have no clear pitch.
- If a reading jumps to about double or half your usual value, test again. Very quiet or creaky sounds can be read an octave out.
Frequently Asked Questions
What is a normal voice frequency?
For adults, typical speaking frequencies are about 90–155 Hz for men and 165–255 Hz for women, and children are higher. Plenty of healthy voices fall outside these ranges.
What Hz is a deep voice?
For speech, a median under about 100 Hz is very deep, and about 100–130 Hz is deep. For singing, bass voices reach down to around 82 Hz (E2) and sometimes lower.
Can I change my voice frequency?
You can raise or lower your speaking pitch a little with practice, and your resonance can make a voice sound fuller or deeper. Big changes are best done with a voice teacher or speech therapist, so you don’t strain your voice.
Is the voice Hz test free and private?
Yes. It’s free and needs no app or sign-up. Your voice is analysed in your browser and is never recorded or uploaded.
Does it work on my phone?
Yes, in current mobile browsers such as Chrome and Safari. Allow microphone access when asked. If nothing happens, check the site’s microphone permission in your browser settings.
