Change the pitch of your voice online: record yourself with the microphone or open a vocal file, choose a voice (deeper, higher, male to female, female to male or chipmunk) or any shift from −12 to +12 semitones, compare before and after, and download MP3 or WAV. Formant correction keeps it natural, and nothing is uploaded.

How to change the pitch of your voice
- Record or open your voice. Press Record your voice, allow the microphone, speak or sing, then press Stop recording. Or open a voice memo or vocal track (MP3, WAV, M4A, OGG, FLAC).
- Choose how it should sound. Tap Deeper, Higher, Male → female, Female → male or Chipmunk, or set any value with −1 and +1. One step is one semitone (what semitones are).
- Listen before and after. Press Play and switch between Before and After at the same spot.
- Download. The file name carries the shift, for example
voice-recording_+4st.mp3.
This vocal pitch changer (some call it a voice pitch changer or vocal pitcher) works in any current browser on a phone or computer, so you can change voice pitch without installing an app. More options holds fine tuning in cents, the formant correction switch and the file format: MP3 at 192 kbps, or lossless WAV.
Why a shifted voice sounds like a chipmunk
A voice has two parts: the note and the tone. The note comes from how fast your vocal folds vibrate. The tone comes from the shape of your throat and mouth, which boosts a few fixed frequency bands called formants. Formants are why an “ah” sounds like “ah” at any note, and why you recognise a friend on the phone.
Plain pitch shifting moves both. Raise a voice by 12 semitones and its formants also double, as if the singer’s throat had shrunk to half its size. That is the chipmunk sound; the classic chipmunk records were made by recording slowly and playing the tape back at double speed. Formant correction moves only the note and puts the formants back where they were, so the voice stays human. It is on by default; the Chipmunk preset turns it off on purpose. To turn any shift into a frequency ratio, use the semitone calculator.
| Preset | Shift | Formant correction | A 120 Hz voice becomes | A 210 Hz voice becomes | What you hear |
|---|---|---|---|---|---|
| Deeper | −3 semitones | On | 101 Hz | 177 Hz | The same person, lower and warmer |
| Higher | +3 semitones | On | 143 Hz | 250 Hz | The same person, lighter and brighter |
| Male → female | +4 semitones | On | 151 Hz | 265 Hz | A higher voice with the same tone; a starting point, not a new person |
| Female → male | −4 semitones | On | 95 Hz | 167 Hz | A lower voice with the same tone |
| Chipmunk | +12 semitones | Off | 240 Hz | 420 Hz | The cartoon sound: tone and pitch both jump an octave |
Can it turn a male voice into a female voice?
Partly, and it is fair to say how far. Typical adult speaking pitch is about 85 to 155 Hz for men and 165 to 255 Hz for women. The Male → female preset moves a 120 Hz voice to 151 Hz: the overlap zone where many voices could be either. Reaching an average female 210 Hz takes almost 10 semitones, and that far a male voice sounds strained, not female.
The rest of the difference is not pitch. Women’s formants are roughly 15 to 20 percent higher (a shorter vocal tract), and breathiness, intonation and articulation differ too. This tool either keeps the formants or moves them fully with the note, with nothing in between, so the gender presets give a convincing higher or lower version of the same speaker, not a different person. Try +5 to +7 for a higher result, and keep shifts under ±7 semitones for natural speech. For songs, male to female key change and female to male key change explain how many semitones a duet partner usually needs.
Singing and practice uses
- Hear your song in a new key before you learn it. Record one verse, try −2 or +2, and listen: if a line feels too high or too low, that is your answer, and what key should I sing in shows how to pick the key.
- Build a harmony by ear. Record the melody, shift it +3 or +4 (a third) or +7 (a fifth), and sing along with the result. The pitch shifter guide for singers lists which intervals sound good.
- Check your own tuning. Retune a take by a few cents under More options to hear whether it was a little flat or sharp.
- Voice-over and content. Lower a narration by 1 to 2 semitones for a calmer tone, or match two recordings of the same speaker.
Privacy: your voice stays on your device
The recording never leaves your browser. The microphone is opened only when you press Record your voice, and it is released the moment you press Stop recording. The audio is kept in the open tab, processed there, and gone when you close it. There is no account, no server copy and no voice data sent to us; our data security page has the details. If the browser blocks the microphone, the tool says what to change, and you can always open a voice memo from your phone instead.

Questions about changing voice pitch
How do I change the pitch of my voice?
Record or open your voice in the tool above, pick a preset or a number of semitones, and download the result. The speed stays the same, so a 30-second message still lasts 30 seconds.
Can you change the pitch of your real voice?
In a recording, yes; in life, a little. Your speaking pitch can move a few semitones with training and relaxed breathing, and vocal exercises to increase range help singers extend it. This tool changes the recording, not your throat.
Is this autotune or pitch correction?
No. It moves every note by the same amount. Pulling wrong notes onto the right ones is pitch correction; see the best pitch correction software for that.
How many semitones make a voice sound female or male?
Start with +4 or −4 and formant correction on. +5 to +7 gets higher, but the result stays the same speaker. For singing a song in a new key, the chart on how many semitones to change key gives exact numbers.
Why does my shifted voice sound robotic?
Big shifts and noisy recordings show the processing. Record close to the microphone in a quiet room, keep shifts within ±5 semitones for speech, and leave formant correction on.
Is my recording uploaded or saved?
No. It is recorded and processed in your browser, and it disappears when you close the page. Nothing is sent to a server, and there is no sign-up or watermark.
Tested: what we measured
- Every preset and control re-measured on the downloaded file: pitch within 0.1 cents of the target, length identical to the sample.
- Formant correction on a synthetic vowel: the tone error fell from 7.6 dB to 2.0 dB for Male → female, so the vowel kept its resonances.
- A real microphone recording (a 440 Hz test signal fed to the browser) shifted +4 semitones came back at 554.38 Hz: 554.37 Hz was the target.
- Microphone blocked, missing or busy: each case shows a plain message with the fix.
