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  • Do not publish accusations about individuals based on an automated score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.
