Sign your voice
VoiceSign adds an invisible signature with your name to a voice recording. If someone reuses the file later, you can check whether your signature is in it.
- Free, no account
- Audio processed in memory
- WAV, MP3, FLAC, M4A, up to 50 MB
How it works
Three steps, under a minute.
You need a recording of your voice and a name. Nothing to install.
01
Enter your name
Type your full name. It is what the signature carries.
02
Upload a recording
WAV, MP3, FLAC, or M4A, up to 50 MB.
03
Download the signed file
You get a signed WAV file. Keep it: we cannot give it back to you.
Before you start
Keep your name and code. We cannot recover them.
To check a signature later, you must enter the exact same name, and the same secret code if you set one. Both are case-sensitive.
Your name and code
We do not keep your name or your code, so we cannot reset them. If you forget either one, the signature can no longer be checked.
Your signed file
We do not keep your audio, so we cannot send the signed file again. Save it as soon as it is ready.
Sign
Sign your voice.
Your name is added to the recording as a signature you cannot hear.
Check
Check a signature.
Upload a signed file and enter the name of the person who signed it. We tell you whether the signature matches.
Your data
What happens to your audio and your name.
The short version. The privacy policy has the full detail.
No account
Upload, sign, download. There is nothing to register.
Audio processed in memory
On this page, your audio and your name are processed in memory and are not kept after the file is returned to you. We keep only a daily count of signatures and checks, to measure use and prevent abuse.
Fair-use limits
To keep the tool free for everyone, the number of signatures and checks per hour is limited for each connection.

Received a suspicious voice?
Signing protects your voice. To check a recording someone sent you, upload it for a result in three bands, with a synthetic-voice score when it is conclusive. One quick check is free each day.

No data recovery. Because we do not keep your audio, your name, or your code, we cannot retrieve or restore any file or detail after processing. You are responsible for saving your signed file and remembering the exact name and code you used.
Voice analysis. Audio is deleted after analysis. Reports are kept at least 30 days, then deleted automatically (35 days after creation; 30 days for full and expert reports); you can ask us to delete them sooner.
No guarantee. This service is provided "as is". A signature may not be found in a recording that has been edited, and a missing signature does not prove a file is fake. See the Terms of Service for liability limits.
