What is the frequency of your voice? This free voice Hz test measures it with your microphone. Read a short passage to find your average speaking frequency, or hold a steady “ah” to see the exact frequency and note you’re producing. You’ll get your median and average frequency in Hz, your typical range, your nearest note and how much your pitch varies.
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.

Your voice is analysed in this browser. Nothing is recorded or uploaded. Results are estimates and depend on your microphone and room.
How to Measure Your Voice Frequency
- Choose Speaking voice to read the passage aloud for about 15 seconds at your normal pitch, or Steady note to hold one sound.
- Press Start test and allow microphone access.
- Speak or sing naturally. The live display shows the frequency and the nearest note as you go.
- Press Stop (the speaking test stops by itself) and read your results.
Speak the way you would in a normal conversation. Reading louder, more slowly or in a “presentation voice” usually raises the result.
Average Voice Frequency: Men, Women and Children
| Voice | Typical speaking frequency | Nearest notes |
|---|---|---|
| Adult men | 90–155 Hz | about F♯2 to D♯3 |
| Adult women | 165–255 Hz | about E3 to C4 |
| Children | about 250–300 Hz and higher | around C4–D4 |
The adult ranges are the typical ranges for voiced speech published in speech science (Baken, Clinical Measurement of Speech and Voice), and the test shows your result against them. Many voices fall outside these bands and are perfectly healthy: they are averages, not rules. Children’s voices vary with age and fall at puberty, most in boys, whose voices drop by about an octave.
What Your Results Mean
- Median frequency: the middle value of everything you said, the best single number for your speaking pitch.
- Average frequency: the mean, which rises when you emphasise words.
- Typical range (middle 80%): where most of your speech sits, leaving out the extremes.
- Lowest and highest stable: the lowest and highest steady pitches measured.
- Nearest note: your median frequency as a musical note.
- Pitch variation: how much your voice moves up and down. A lively voice varies more; a monotone voice varies less.
What Your Median Frequency Means
| Median speaking frequency | How it usually sounds |
|---|---|
| Below 90 Hz | Very deep; below the typical adult male range |
| 90–155 Hz | Typical adult male speaking voice |
| 155–165 Hz | The overlap zone: can be heard as a higher male or a lower female voice |
| 165–255 Hz | Typical adult female speaking voice |
| Above 255 Hz | High; typical of children and some higher female voices |
Pitch is only one part of how a voice is perceived. Resonance, loudness, speech melody and articulation matter at least as much, which is why two people with the same median frequency can sound quite different.
How the Test Measures Your Voice
While you speak, the test takes about 30 measurements a second. For each one it checks whether the sound is voiced (vowels and voiced consonants have a clear pitch; whispers, pauses and sounds like “s” and “f” do not) and, if it is, finds the fundamental frequency, the rate at which your vocal folds vibrate. Unvoiced moments are left out. Your result is the median of all voiced measurements, so a few very high or low moments don’t distort it.
Using the Steady Note Mode
Choose Steady note to measure one sustained sound instead of speech. Hold a comfortable “ah” for a few seconds: the result shows its exact frequency, the nearest note and how steady it was. This is useful for checking the note you naturally hum, comparing a sung note with a reference, or tracking a single pitch during voice exercises.
Speaking Frequency vs Singing Range
Your speaking voice uses only a small, low part of your range, usually a few semitones near the bottom. Your singing range is much wider, often two octaves or more (see typical vocal ranges). A low speaking voice often goes with a lower voice type, but not always, so to find your voice type measure your singing range with the voice type test or the vocal range calculator.
Why Your Voice Frequency Changes
- Time of day: voices are often lower in the morning.
- Emotion and energy: excitement and stress raise pitch; tiredness lowers it.
- Health: a cold or a swollen throat lowers the voice for a while.
- Age: women’s voices tend to lower slowly after menopause, men’s may rise slightly in old age.
The physics behind this is simple: pitch rises when the vocal folds are thinner, tighter or vibrate faster. How vocal cords produce pitch explains it step by step, and why vocal range changes covers the longer-term changes.
Tips for an Accurate Measurement
- Use a quiet room; background voices and music confuse the measurement.
- Keep the device 20–40 cm from your mouth and speak at a normal volume.
- Test two or three times and compare the median values.
- Whispers and very breathy speech have no clear pitch and are skipped.
Already Have a Frequency?
If you know a frequency and want the note, use the frequency to note converter (the test also has a small converter under the results). For live, note-by-note singing feedback with cents, use the pitch detector. How the voice box makes sound in the first place is covered in how the vocal cords work.
Frequently Asked Questions
What is a normal voice frequency?
For adult speech, about 90–155 Hz for men and 165–255 Hz for women, with wide individual differences.
Is 100 Hz a deep voice?
For a man, 100 Hz is in the lower part of the typical range, a fairly deep speaking voice. For a woman it would be unusually low.
Can I change my voice frequency?
Yes, within limits. Voice training can shift the comfortable speaking pitch by a few semitones and improve resonance; do it gradually, ideally with a voice teacher or speech therapist.
Is my voice recorded?
No. Your voice is analysed in your browser and never uploaded.
