Voice AI Checker
Free AI voice detector for suspicious voice clips
About Voice AI Checker
Voice AI Checker is a free web tool for a narrow but increasingly common question: does this voice clip sound like a real person or like AI-generated speech? Voice cloning has made scam voicemails, fake endorsements and synthetic narration cheap to produce, and most people have no way to get a second opinion before they act on a suspicious clip. Voice AI Checker lets anyone upload or record a short sample in the browser and get a screening result in seconds, with one check a day available without creating an account.
The site is careful about what the result means. It returns a probability-style signal labelled likely AI, likely human or unclear, and repeatedly describes it as a risk signal rather than proof. Detection itself is powered by Modulate's Velma-2 Synthetic Voice Detection API, which the site names openly, and the same model runs on free and paid checks alike, so paying buys more checks rather than a different answer. Around the main detector sit separate pages for AI audio, deepfake audio, voice clone checks and a free beta for AI song detection, which has its own daily limit.
You upload an MP3, WAV, M4A, OGG, MP4 or WEBM file, or record directly in the browser. You then pick the analysis window: anonymous users can analyse up to 15 seconds and signed-in users up to 30 seconds, and the site recommends a clean 10 to 30 second stretch with a single speaker. The browser prepares a short WAV sample and only that selected window is sent for detection, so long uploads are trimmed rather than sent in full. Within a few seconds you get the label and a confidence score, along with guidance on how to read it. If the result is unclear, the advice is to try a cleaner section of the same voice rather than re-running a noisy file.
- •Free daily checks - One check per UTC day without signing up, or three per day after an optional Google sign-in, with no payment needed for basic use.
- •Three-way verdict - Results come back as likely AI, likely human or unclear, plus a confidence score, so ambiguous audio is flagged as ambiguous instead of being forced into a yes or no.
- •Selected-window analysis - You choose the part of the clip to analyse, which keeps the sample short, avoids music and crosstalk, and limits how much audio leaves your device.
- •Named detection model - Checks run on Modulate's Velma-2 Synthetic Voice Detection API, and the site states the same technology is used on every plan.
- •Specialised detector pages - Separate entry points for deepfake audio, AI audio in narration and podcasts, voice clones and a beta AI song detector cover different kinds of suspicious media.
- •Credit refunds on failure - Failed or server-error detections return the reserved check or credit automatically.
Voice AI Checker is useful for anyone who receives a voice message asking for money, credentials or urgent action and wants a quick first read before verifying through a trusted channel. Journalists and social media moderators can screen a viral clip before reposting it. People who review ads, podcasts or video narration can flag audio that may have been generated by AI voice tools. Small businesses worried about voice-based impersonation can give staff a simple screening step. Regular reviewers who need more than the daily allowance can move to the Pro plan or buy a one-time pack of checks.
