How to read it
Hz means the fundamental
The number is how many times a second your vocal folds open and close, read from 10 seconds of speech. It moves with mood, time of day and the sentence you say, so measure twice before you trust it.
Sample
Average 118.4 Hz, B♭2 +27 cents. Lowest 98.2 Hz, highest 164.0 Hz, a range of 8.9 semitones.

How this test works
Every moment of sound is compared with a copy of itself moved along in time; the shift at which the two line up best is one cycle of your voice.
Only steady, voiced moments count. Hiss, clicks and silence print a dash and are left out of the result.
A run is 10 seconds. The result is the middle reading, the nearest note, and the lowest and highest steady readings.
This voice Hz test listens while you speak or hum. It shows the pitch of your voice in hertz and as a note name, live and as a 10-second average. The result is that number and that note, nothing more. This page's own code measures the sound as it arrives and keeps numbers, never audio.

Take a 10-second reading
Press Start listening and allow the microphone. Read the line above the meter in your ordinary voice, or pick Hum one steady note under Line to read. After 10 seconds the run ends with your average in Hz, the lowest and highest steady readings, and the span between them in semitones.
Place the number on the table
Hertz here counts how many times a second your vocal folds open and close. The page highlights the nearest landmark, such as A2, 110 Hz or A3, 220 Hz. Every octave doubles the figure. A reading that leaps from 110 to 220 and back is the meter slipping an octave. See The number doubles or halves mid-word. The average is the middle reading of the run, so stray readings hardly shift it.
Read the same line on every run. Averages compare fairly only across the same words.
Measure in a quiet room, a hand's width from the microphone. If no number appears, the mic test with playback shows what the input picks up.
This page's own code measures the pitch as the sound arrives and never records, uploads or keeps it. What stays in this browser is numbers only: your last ten results, which you can clear. The microphone is released when a run ends or you hide the tab.
Is my number normal, and can it show a voice problem?
The page gives a number and a note name, attaches no verdict and cannot assess a voice. The table quotes one published pair of speaking ranges with its source: 90 to 155 Hz for adult men, 165 to 255 Hz for adult women. They describe typical talkers, not limits, and speech as a whole runs from roughly 40 Hz to 600 Hz. If your voice has changed or stays hoarse, see a doctor or a speech and language therapist.
Why does the number jump around while I talk?
Speech is not a held note. Pitch tends to fall at the end of a statement and step up at the end of a yes or no question. It vanishes on voiceless sounds such as s, f and t. Hum one steady note to see how still the reading can be.

Landmark notes from C2 to C6 14
C2, 65.41 HzThe lowest open string of a cello, and the bottom of this meter's range. One cycle lasts 15.29 ms, and the page has to watch a cycle repeat before it can call a sound a pitch, so a note this low needs about 31 ms of steady sound. The next semitone up is only 3.89 Hz away.
E2, 82.41 HzThe lowest string of a guitar in standard tuning. In air at 20 °C one cycle of this note is 4.16 metres long. If the live number hops between 82 and 165 Hz while you hold it, the meter is catching the second harmonic, the same note name an octave up.
G2, 98 HzThe second-lowest string of a cello. It sits 35 cents below 100 Hz, the hum that equipment makes where the mains supply is 50 Hz, so a rock-steady reading just above this row while nobody speaks is more likely wiring than a voice.

Landmark notes from C2 to C6, continued
A2, 110 HzExactly two octaves under the 440 Hz tuning standard, because each octave down halves the frequency: 440, 220, 110. It is also a guitar's open A string. A semitone at this height is 6.54 Hz wide, so a drift of 3 Hz is 47 cents, nearly half a semitone.
C3, 130.81 HzOne octave below middle C and the lowest open string of a viola. One cycle lasts 7.64 ms. Every octave doubles the frequency, so the climb from here to middle C covers 130.81 Hz, while the octave below this row covers only 65.41 Hz.
D3, 146.83 HzThe open D string of both a guitar and a cello. A voice makes sound by chopping a steady flow of air into puffs as the vocal folds open and close. Held at this pitch they do so about 147 times a second, and that rate is the number the meter reports.
E3, 164.81 HzOne octave above a guitar's lowest string. Each fret raises a string by one semitone and twelve semitones make an octave, so this is the note at the twelfth fret, which sits at half the string's length. A semitone here is 9.8 Hz wide, exactly twice its width at E2.
G3, 196 HzThe lowest note of a violin, and the open G string of a guitar and a viola. One cycle lasts 5.1 ms, so ten seconds held at this pitch is 1,960 cycles, far more than the page needs for a settled average.
A3, 220 HzThe top string of a cello, one octave under the tuning standard. In air one cycle is 1.56 metres long. A semitone is 13.08 Hz wide here against 6.54 Hz at A2, which is why the page prints cents beside the note: a cent is the same musical distance at any height.
C4, 261.63 HzMiddle C, the start of the fourth octave in scientific pitch notation and the low C string of a ukulele in standard tuning. It is the check value for this whole table: 440 × 2^(−9/12) has to come out at 261.63 Hz, and it does.
E4, 329.63 HzA guitar's top string, two octaves above its lowest, so the six open strings span exactly two octaves. Two octaves up multiplies the frequency by four, which takes 82.41 Hz to 329.63 Hz. One cycle lasts 3.03 ms.
A4, 440 HzThe international tuning standard, ISO 16: the A above middle C. A violinist tunes the A string to it first, and every other row in this table is calculated from it. Some orchestras tune a few hertz higher, which shifts their note names but not the Hz your voice produces.
E5, 659.26 HzThe top open string of a violin. One cycle lasts 1.52 ms. A reference article on pitch detection puts the fundamental of speech between about 40 Hz and 600 Hz across all voices, so this row sits just above talking. Sung notes and a good shout go higher.
C6, 1,046.5 HzTwo octaves above middle C and the top of this meter's range: 1,046.5 Hz is 16 times C2, four doublings. One cycle lasts under a millisecond, 0.96 ms. Above this the page prints 'above range' and does not guess.
Published speaking ranges, for reference only 2
Published speaking range, adult men: 90 to 155 HzA reference article on voice frequency gives 90 to 155 Hz as the fundamental of a typical adult man's voiced speech, citing a clinical handbook (Baken, Clinical Measurement of Speech and Voice, 2nd edition, 2000, page 177). On this table that runs from between E2 and G2 up to between D3 and E3. It describes adult talkers as a group, not children and not singing, and it is neither a limit nor a target.
Published speaking range, adult women: 165 to 255 HzThe same source gives 165 to 255 Hz for a typical adult woman's voiced speech: from E3, at 164.81 Hz, to about 44 cents under middle C. The two published ranges stop 10 Hz short of each other, which shows what they are: round figures for typical speakers, not borders. The E5 row gives the span for all voices, about 40 Hz to 600 Hz. This page never sets either range beside your result.
Lines to read aloud, every sound voiced 4
We were all warm in our own room.A statement. Every sound in it is a vowel, a nasal or one of w, r, l and y, all made with the vocal folds vibrating, so the live number should run unbroken from the first word to the last. English statements tend to end on a falling pitch, so watch the number drop on 'room'.
Rain ran along our lawn all morning.A second unbroken line, with no s, t, k, p, f, sh or h to interrupt the reading. Make it your fixed line and say it in your talking voice, not a reading-aloud voice. A speaking average only means something beside earlier runs of the same words said the same way.
Are you really well now?A yes or no question. In English, and in American English most of all, the pitch steps up on the last stressed word and stays high, so this line should finish higher than it began and widen the range the run reports.
One yellow lemon, one melon, one lime.A list. Speakers commonly lift each item and let the last one fall, as in the textbook example of red, blue, green, yellow or black. Count the rises in the live trace: it shows how far your pitch travels inside a single breath.
Readings that need a second look 6
The number doubles or halves mid-wordAn octave error, the best-known mistake in pitch detection. The meter compares the sound with a delayed copy of itself. A steady voice also matches itself two cycles later, which halves the reading, and a strong second harmonic nearly matches after half a cycle, which doubles it. A hop from 110 to 220 Hz and back is the same note name, A. Your voice did not leap.
The number blanks on s, f, t, k, p, sh and hThose sounds are voiceless: the larynx does not vibrate, so there is hiss and no frequency to report. Try 'sss' and then 'zzz', or 'fff' and then 'vvv'. The mouth shape is the same, and only the second of each pair gives a number. A whisper is voiceless all the way through, so it reads nothing.
A low, crackling reading as a sentence trails offCreaky voice, also called vocal fry, the lowest vocal register. The folds go slack and let air bubble through in slow, irregular pops. With no regular cycle there is no single frequency, so the meter may show a very low number, jump about or go blank. The run's average counts steady frames only.
A steady 100 Hz or 120 Hz while nobody speaksMains hum. Equipment on a 50 Hz supply hums at 100 Hz, which is G2 plus 35 cents, and on a 60 Hz supply at 120 Hz, midway between B♭2 (116.54 Hz) and B2 (123.47 Hz). A reading that never moves, at one of those two figures, comes from a power supply or a cable and not from a voice. Try battery power or a different cable.
A held note that wavers several times a secondVibrato. One reference on singing gives rates from under 5 to about 8 wavers a second, and a solo singer's vibrato usually stays within a semitone either side of the note, a choir singer's within a tenth of that. The live number follows the waver up and down. The average lands near its centre.
Music or a second voice in the roomThe meter follows one pitch at a time. Detectors of this kind do not deal well with several notes at once, so a radio, a television or a friend talking pulls the number towards whichever sound is strongest at that instant. Measure in a quiet room, or use a headset microphone close to your mouth.
Before you trust the number 4
No number appears when you speakThe microphone is blocked, the wrong input is selected, or the level is too low for the page to find a cycle. Watch the level bar. If it stays still while you talk, open the padlock or site settings icon beside the address, allow the microphone and reload. Then run the mic test with playback to hear what the input really picks up.
Call processing still switched onBrowsers tidy microphone sound for calls with echo cancellation, noise suppression and automatic gain control. This page asks for all three to be off, because they are built for conversation and not for measurement. A browser may decline any of the three, so the read-out lists what was really applied.
Hz here means the fundamental, not the whole voiceA voice is a stack of harmonics at whole multiples of one lowest frequency, and this meter reports that lowest one. A telephone channel carries only about 300 to 3,400 Hz, which is above the fundamental of most speech, yet callers still hear the right pitch because the harmonics that do arrive imply it.
Note names assume A4 = 440 HzThe Hz figure is a measurement; the note name is a convention laid over it. This page uses equal temperament built on the ISO 16 standard. Orchestras in continental Europe commonly tune A4 anywhere from 440 to 444 Hz, and Baroque groups have settled near 415 Hz, where 440 Hz would be called A sharp.
