AI Voice Detector: Check If a Voice Is AI or Human

What an AI or human voice detector actually does

Speech generators build a voice from patterns they learned. Even when a cloned voice sounds natural to us, it can carry small acoustic traces that real vocal cords and real rooms do not produce. An AI generated voice detector looks for those traces and weighs them up. It does not recognise who is speaking, and it cannot read the speaker's intentions. It answers one narrow question: does this audio look more like synthetic speech or more like a person talking? For a plain-language explanation of the method, read how voice deepfake detection works.

The three results, and how to read them

• Likely AI: the recording shows signs commonly left by voice generators. Treat the message as suspicious and verify through another channel before you do anything.
• Likely real: we did not find strong signs of AI generation. This does not prove who is speaking. A real person can still be a scammer, and a real voice can be edited or taken out of context.
• Unsure: the evidence is too weak either way. We would rather say so than give you a confident answer we cannot back up.

Every result is decision support, not proof. It should add to your judgement, not replace it.

Built for phone audio and Indian languages

Many general-purpose detectors are trained mostly on clean, studio-quality English. Real scam audio is rarely like that. It arrives as a compressed WhatsApp voice note, a call recording made on a cheap phone, or speech in Hindi, Tamil, Bengali or another Indian language mixed with English. SpotAClone is built with that kind of audio in mind. It works for people in India, the US, the UK, the UAE, Singapore and elsewhere. If you prefer to read in Hindi, see the Hindi page.

Is an AI voice detector legit? Know the limits

Any detector, including this one, can be wrong. Results are less reliable when:

• the clip is very short (a few seconds of speech)
• the audio has been compressed heavily or forwarded many times
• there is loud background noise, music or several people talking
• the voice was made with a newer generator the detector has not seen before

In these cases you may get Unsure, and false results in either direction are possible. That is why the next step matters more than the score.

What to do next

1. Call the person back on a number you already know. Do not use the number that sent the message.
2. Never share an OTP, PIN, UPI PIN or password. Banks never ask for them.
3. Agree a family code word that a caller must say before anyone sends money.
4. In India, report fraud at cybercrime.gov.in or call 1930. In the US you can report at reportfraud.ftc.gov. In the UK, contact Action Fraud. Elsewhere, contact your local police or national fraud reporting service.

If money has already left your account, read what to do if you sent money to a scammer.

Privacy

Your audio is analysed and deleted immediately. It is never stored. Nothing you upload is kept after the result is shown.

More ways to check

If you think someone has copied a specific person's voice, the voice clone detector page covers that case. For a message that arrived on WhatsApp, the WhatsApp voice note checker shows how to get the file out of the app. Need more than 3 checks a day? See pricing. Developers can add checks to their own apps with the VoxShield API.
