Voice Changer — Free, No Sign-Up
Choose a voice recording, pick a pitch and speed, add an effect if you like, and preview it before you download.
Honest note: pitch and speed change together, like a tape recorder — a higher voice also plays faster. That is how a browser voice changer really works.
How to use Voice Changer
Choose a voice recording
Click the box above or drop an MP3, WAV, OGG or M4A recording onto it. Any voice note, clip or song works.
Pick a pitch and speed
Move the pitch slider — left for a deep voice, right for a high “chipmunk” voice. Add echo for a cave sound, or robot for a machine voice. Press “Preview voice” to hear it.
Download the changed voice
Press “Change Voice & Download”. Your changed voice downloads as a WAV file, ready to share or use in a video.
Example: Example: record “Hello, how are you?” and set pitch to 1.8 with echo — you get a high, echoing voice that sounds like a cartoon character in a cave.
About Voice Changer
A voice changer turns an ordinary recording into something fun: a high cartoon voice, a deep movie-trailer voice, a robot, or a voice echoing in a cave. AudioTools changes your voice right in your browser — pitch and speed together, plus echo and a robot ring-modulation effect — and you can preview the result before you download it. There is no upload, so your recordings stay private, and everything is free, with no account and no sign-up.
One honest note: pitch and speed change together here, the way a tape recorder works — a higher voice also plays faster, and a lower voice plays slower. That is the honest, real-time way a browser can change a voice without a server. The result downloads as a WAV file, which opens in every audio app and video editor.
Frequently asked questions
How do I change my voice online?
Choose a voice recording, move the pitch slider, add echo or robot if you like, press “Preview voice” to hear it, then press “Change Voice & Download”.
Can I make my voice sound like a robot?
Yes. Tick the robot effect — it adds a machine-like ring modulation to your voice. Combine it with a low pitch for a deeper robot.
Does pitch change the speed too?
Yes, honestly: pitch and speed change together, like a tape recorder. A higher voice plays faster, a lower voice plays slower. That is how a browser voice changer really works.
Is the voice changer free?
Yes. Changing your voice on AudioTools is 100% free. There is no paid plan, no length limit and no watermark.
Do my recordings get uploaded?
No. The voice change happens entirely in your browser. Your files never leave your device and nothing is stored on any server.
What format does the changed voice download as?
WAV — uncompressed, full quality, and playable in every audio app and video editor. MP3 export is not possible in a browser.
