About this check
What Detect Fake Voice Call actually does.
Targeted page for voice-call scams — the 'grandparent scam', vishing, and CEO-impersonation calls that increasingly use cloned voices. The engine prioritizes signals that survive phone-line compression, since clean studio audio is rarely the input.
How it works
- 1Cadence uniformity catches the unnaturally even pacing of synthesized speech.
- 2Voiceprint stability flags pitch and timbre that hold too steady across the clip.
- 3Background continuity reviews ambient noise for signs of a generated or stitched call.
When to use it
Real situations this page is built for.
- A relative receives a panicked call from a 'family member' asking for urgent money.
- A finance team is asked to wire funds based on a verbal CEO instruction.
- A call recording surfaces that allegedly captures a private conversation.
Limitations
Compressed phone audio loses fine signal. Always use a callback to a verified number to confirm identity in real life.
Honest scope
What this detector does not do.
Naming the gaps explicitly so the score is interpreted in context.
- Whether the speaker actually said what was claimed in another medium.
- Identity matching against a specific real speaker without a reference.
- Background music or song authenticity (use the music detector).
FAQ
Detect Fake Voice Call questions
Can it detect a clone of my own voice?
It detects synthesis markers, not personalized matches. Voice-match against a reference is a different feature.
What format should I upload?
WAV is best. MP3 from the call recorder works.
Does it work on voicemails?
Yes, treating them as a one-sided call clip.
