20 scam scripts we map against.
Resemble Signal — the enterprise call-screening engine — maps every uploaded call against 20 known voice-fraud patterns. The free tool flags AI voice today; full-category classification ships with the Signal integration.
For consumers
If a caller claims to be a relative in trouble, a bank officer, or a government agent asking for urgent action — hang up and verify through a channel you trust. Record the voicemail (most phones allow this), upload it here, and confirm before you act.
- · Never wire money based on a voice call alone.
- · Ask a question only the real person would know.
- · Call back the official number — not the one that called you.
For call centers & banks
Resemble Signal classifies scam calls in real-time across the 20 categories above. Deploy it in front of your call center, IVR, or customer-service pipeline to flag synthetic callers and match them to known fraud scripts before an agent picks up.
Frequently asked questions
- What counts as a "scam call" for this tool?
- Any recorded audio where a suspicious caller uses social-engineering tactics — impersonating a bank, authority, relative, or executive to extract money, credentials, or access. The detector identifies if the caller's voice is AI-generated; the pattern classifier (via Resemble Signal) maps the call to one of 20 known scam scripts.
- Will this catch vishing calls?
- Yes. Vishing — "voice phishing" — is a direct subset of what this tool screens. Any recorded voicemail or call can be uploaded. For real-time call screening at scale, see the Resemble Signal enterprise product.
- How do I record a call on my phone?
- iOS 18.1+: open Phone → during the call, tap the waveform icon → record. Android: most OEMs (Samsung, Pixel) have built-in call recording in the Phone app. For voicemails, many carriers let you forward them to email (check your carrier's voicemail settings).
- Can the tool tell me who the attacker is?
- It can tell you the likely generator family (ElevenLabs, Resemble, OpenAI TTS, etc.) of a synthetic voice, but not the identity of the human orchestrating the scam. For criminal investigation, file with the FBI IC3 at ic3.gov and preserve the audio.
- What should I do if I confirm a scam?
- (1) Do not call back or engage. (2) Report to the FTC at reportfraud.ftc.gov. (3) If money was sent, contact your bank immediately and the FBI IC3. (4) If an executive was impersonated, alert your security team before any wire is executed.
