Robot Voice Recorder
Record your voice and turn it into a robot in one place. Nothing is uploaded, and the WAV export is one click away.
Your browser does not fully support the Web Audio API. Try Chrome, Edge, or Firefox for the voice changer.
Audio is processed locally and never uploaded.

From your mic to a robot take
A robot voice recorder collapses the whole chain — capture, effect, and export — into a single page. There is no project to set up and no timeline to configure: you press one button, deliver your line, stop, choose a robot preset, and download. That simplicity makes it the tool of choice for quick Discord soundboards, one-liners for game mods, scratch voice-over auditions, and testing how a robotic read of your script feels before committing to a full studio session.
The recording path is deliberately transparent. While you speak, a timer and a pulsing indicator confirm that audio is being captured, so you never wonder whether the take started. When you stop, the clip is decoded immediately and you see its length before processing, which protects you from accidentally robotizing dead air. Recordings under half a second are rejected with a clear message, and anything longer than a minute is allowed but flagged, since offline rendering of very long clips can take a few seconds even on fast machines.
Privacy is the quiet advantage of a browser-based recorder. The microphone stream goes to the local MediaRecorder, the effect runs in a local offline audio context, and the WAV is assembled in memory — at no point does your voice touch a server, and closing the tab erases everything except the file you chose to download. Prefer starting from text instead? The text to speech page reads any script in a robotic voice, and the voice changer page offers the same effects with a file-upload-first workflow.
Frequently Asked Questions
▸How does the robot voice recorder work?
Press Record, speak into your microphone, and press Stop. Your recording is decoded in the browser, you apply one of the robot effect presets, and you download the processed result as a WAV file. The microphone stream is processed locally and never uploaded.
▸Why does the browser ask for microphone permission?
Recording requires explicit permission per browser security rules. Click Allow in the prompt. If you clicked Block by accident, the recorder shows an error message with guidance — you can re-enable the permission from the lock icon in your browser’s address bar.
▸Can I record on a phone or tablet?
Yes. The recorder uses the standard MediaRecorder API supported by Android Chrome, iOS Safari, and other modern mobile browsers. Earbuds with a built-in mic usually give the cleanest input, which makes the robot effect crisper.
