What Ai-SPY is
Ai-SPY focuses on voice. It analyses recordings, uploaded audio or linked social content and returns an authenticity score with word-level detail, aimed at determining whether a voice was synthesised, with optional expert human review.
What you can do with it
- Check a voice message for synthesis
- Analyse podcast or interview clips
- Review social media audio
- Read word-level detail behind a score
- Integrate checks through an API
Who it is for
- Media and brand verification teams
- Platforms handling user audio
- Investigators working with consent
What to watch out for
- Authenticity scores are probabilistic; a confident number is not proof, and both false positives and false negatives occur
- Uploading someone else's voice for analysis is processing their biometric data, so consent matters
- Do not publish accusations about individuals based on an automated score
- Synthetic voice detection lags generation quality, so a clean result is not a guarantee

FAQ
Does a score prove a voice is fake?
No. It is a probabilistic signal that needs corroboration.
Can I analyse someone else's recording?
Only with consent, since voice analysis is biometric processing in many jurisdictions.
What should I avoid?
Publicly accusing someone on the basis of an automated result.
