What this checker looks at
Synthetic prosody
Cloned speech breathes in the wrong places, holds an unnaturally even pace and lands emotion slightly late.
Room tone and noise floor
Real recordings carry a consistent background. Generated speech has a suspiciously clean or looping noise floor.
Splice detection
Sudden changes in level, sample rate or ambience at sentence boundaries suggest sentences were assembled rather than spoken.
Multimodal AI review
A multimodal model listens to the clip and reports what it hears, then names the likely synthesis tool when the traits match a known one.
How to use it
- 1
Drop an MP3, WAV or M4A recording onto the box above, up to 8 MB on the free check.
- 2
Use the longest clean stretch of speech you have. Ten seconds of uninterrupted talking beats a minute of crosstalk.
- 3
Read the verdict and the specific observations before you act on the call — especially if the caller is asking for a payment or a password.
- 4
If you are investigating a case, create a free workspace so the recording is sealed with a hash and an append-only history.
Questions
Frequently, yes. Synthetic speech leaves prosody and noise-floor traces, and the AI review is prompted to attribute the clip to a known synthesis tool when its traits match.
