How the Voice Hz Test Works
A voice Hz test measures your fundamental frequency, written F0: the number of times per second your vocal folds open and close while you speak. That rate, expressed in hertz, is what you hear as pitch. A voice at 110 Hz is vibrating 110 times a second and sounds like the note A2; a voice at 220 Hz vibrates twice as fast and sounds an octave higher, at A3.
This tool takes the recording, splits it into 40-millisecond frames stepped every 20 milliseconds, and drops any frame that is silent. On every frame that remains it runs the McLeod pitch method, a normalised autocorrelation that searches between 60 and 500 Hz for the strongest repeating period. Frames where no clear period stands out, which is what unvoiced consonants, breaths and background noise look like, are gated out and never enter the statistics. What is left is a list of one pitch reading per voiced frame, typically a few hundred readings for an eight-second take.
The headline figure is the median of that list. The median is the middle reading when all of them are sorted, and it barely moves if a handful of frames misfire. The average is shown next to it because many other tools report the average, and you may want to compare. The two usually sit within a few hertz of each other; when the average is noticeably higher, your pitch rose on a few emphasised words.

Reading Your Result
The result panel shows six core readings, and each one answers a slightly different question. Two extra cards round it off: your range in this take, in semitones, and a voice type label.
Example result · sample recording, not your voice
Below the cards, a scale shows where your median sits against the ranges typical of adult speakers, and the raw panel lists every underlying measurement, including the formants and the harmonic-to-noise ratio, for anyone who wants the full picture.
What Is a Normal Voice Frequency?
Averaged across a sentence, adult masculine speaking voices typically centre somewhere around 85 to 155 Hz, and adult feminine speaking voices around 165 to 255 Hz. Those are population reference ranges, and plenty of people sit outside them, the two ranges overlap in real life, and a reading between them is common and unremarkable. Children sit higher still, usually well above 250 Hz. We measured 40 real readers to see how the ranges hold up in male vs female voice frequency.
The number also moves within one person. Most voices sit lower first thing in the morning and rise through the day. Excitement, nervousness and raised volume all push pitch up. Reading aloud tends to sit slightly higher and flatter than relaxed conversation. Fatigue and a cold tend to push it down and make it rougher. None of this is a problem for the test; it simply means one reading is a snapshot, and three readings on different days tell you more than one.
The table below converts common speaking pitches to note names, so a figure in hertz can be placed on a piano.
Every semitone step multiplies frequency by about 1.059, so an octave doubles it. So a 20 Hz difference is large at the bottom of the scale and small at the top: 90 to 110 Hz is more than three semitones, while 240 to 260 Hz is barely more than one.
How to Get an Accurate Reading
Speak, do not perform. Read two or three ordinary sentences at the volume you would use across a table. Deliberately lowering or lifting your voice for the microphone gives you a number for that performance only.
Do not whisper. A whisper has no vocal fold vibration at all, so there is no fundamental frequency to measure. The tool will report that it heard sound but no clear vocal tone.
Use a quiet room and a normal distance. Roughly a forearm from the microphone is right. Distance does not change your pitch, but noise and echo make frames harder to classify, and more frames get discarded. Bluetooth headsets and speakerphones often compress or band-limit the signal; a laptop or phone microphone in a quiet room is usually better.
Let it run. The take is eight seconds. Keep talking until the bar fills. A longer sample gives the median more frames to work with and makes the 5th and 95th percentile readings meaningful.
Record three times. If the three medians land within a few hertz of one another, you have a reliable figure. If they scatter, the most likely cause is that you spoke differently each time, and the middle one is the fairest answer.
What People Use a Voice Frequency Test For
Singers use it to find their habitual speaking pitch and compare it with where their singing sits; the two are related but not the same, and a speaking pitch that sits far from someone’s comfortable singing range is often worth a conversation with a teacher. Voice-training communities use it as a repeatable measure of progress, because a change in median pitch over months is visible in a way that a change in how you sound to yourself is not. People who record narration or podcasts use it to check that a new microphone or room has not changed how they come across.
Comparing yourself with yourself is the strongest use. Keep the room, the device, the distance and the passage you read the same, and the median becomes a stable number you can watch over time. Save a reading after each session to build a log, and see how to track voice training progress for how big a change has to be before it counts. Comparing yourself with a population average is the weakest use, because the spread between individuals is much wider than most people expect.
If you want the fuller picture from the same recording, the deep voice test reads the same figure against depth bands and adds resonance, the voice gender detector combines pitch with formants, and the main voice rater adds a 1-10 quality score.
Measured on Real Recordings: Speaking Pitch of 40 Readers
Median speaking pitch of the 40 readers in the LibriSpeech dev-clean set, 12 seconds of reading each, measured with this page's code.
| Group | Median pitch, middle of the group | Lowest to highest median | Typical floor and ceiling in one reading |
|---|---|---|---|
| 20 women | 197 Hz | 150 to 261 Hz | 145 Hz and 281 Hz |
| 20 men | 117 Hz | 91 to 199 Hz | 91 Hz and 187 Hz |
The two groups overlap between about 150 and 199 Hz, so a single Hz figure is a description, not a category. The full measurement is in male vs female voice frequency.
Frequently Asked Questions
Last reviewed: September 2026
How many Hz is my voice?
Press record, speak normally for eight seconds, and the median fundamental frequency of your voice is shown in hertz alongside its nearest musical note. The result also lists your average, your lowest stable and highest readings, and a stability figure, so you can see the shape of the whole take instead of a single number.
What is a normal voice frequency in Hz?
Adult masculine speaking voices typically centre around 85 to 155 Hz and adult feminine voices around 165 to 255 Hz. These are population reference ranges. Many people sit outside them, the ranges overlap, and a reading between the two is common. Children usually sit well above 250 Hz.
What is the difference between median and average pitch?
The average adds every voiced frame together and divides by the count, so a few high frames on emphasised words pull it upward. The median is the middle reading once the frames are sorted, and it ignores those outliers. This tool leads with the median for that reason and shows the average beside it for comparison with other tools.
How does a voice Hz test work?
The recording is cut into 40-millisecond frames. Silent frames are dropped. Each remaining frame is run through the McLeod pitch method, a normalised autocorrelation that finds the strongest repeating period between 60 and 500 Hz. Frames without a clear period, such as breaths and unvoiced consonants, are gated out. The statistics are computed on the voiced frames that remain, entirely inside your browser.
Why is my voice frequency different each time?
Because your pitch genuinely moves. It sits lower in the morning, rises with excitement or volume, sits slightly higher when reading than in conversation, and drops when you are tired or unwell. Deliberately speaking differently for the microphone changes it too. Record three ordinary takes and treat the middle result as your figure.
Does a deeper voice mean a lower Hz?
Lower hertz means a lower pitch, and a lower pitch is the largest part of what listeners call a deep voice. It is not the whole of it. Resonance, which the tool reports as formant frequencies in the raw panel, changes how full or thin a voice sounds at the same pitch. Two voices at 110 Hz can sound quite different for that reason.
Can I test my voice frequency without uploading anything?
Yes. This page has no server capable of receiving audio. The Web Audio API captures the microphone inside the browser tab, the analysis runs there, and the recording is discarded when the tab closes.
What note is my voice?
The result names the equal-temperament note nearest your median pitch, with A4 tuned to 440 Hz. As a guide, 110 Hz is A2, 131 Hz is C3, 165 Hz is E3 and 220 Hz is A3. Speaking pitch sits in a narrow band, so this note describes your speaking habit, and your singing range is a separate measurement.
