AI Voice Detector Guide
How to Detect an AI-Generated or Cloned Voice
Is that voice real or AI-generated? Good voice clones can fool your ear, so reliable AI voice detection comes down to a few checks: verify the speaker through a channel you trust, trace the clip to its original source, and test what the voice actually claims. This guide walks through each one, and BSmeter runs the last check for you: paste a YouTube, TikTok, Instagram Reel, podcast, or audio-file link and BSmeter pulls out the claims and scores each one 0-100.

Why AI Voice Detection Matters Now
AI voice cloning isn't science fiction. Cloned and AI-generated voices are already used in family-emergency scams, fake celebrity endorsements, and political robocalls. Here's what you're up against, and why the checks that work focus on the source and the claims rather than on how a voice sounds.
Voice-Cloning Scams Are Real
The FTC has warned that scammers can clone a loved one's voice from a short clip posted online, then call with a fake emergency to pressure you into sending money, gift cards, or crypto fast.
AI Voices Are Everywhere
Text-to-speech and voice-cloning tools are cheap and widely available, and AI voiceovers are now common on social video. Most are harmless. Some put words in a real person's mouth, like the AI robocalls that imitated President Biden's voice before the January 2024 New Hampshire primary.
Your Ear Isn't Enough
Good voice clones can be hard to tell apart from real speech, and automated AI voice detection tools make mistakes too. Verifying the source and checking the claims is more dependable than judging how a voice sounds.
How to Detect an AI Voice: 3 Checks That Work
Three checks that hold up whether a voice is real, synthetic, or cloned. The first two need no software at all.
1. Verify Through Another Channel
Got an urgent call or voice note from a 'family member' or 'your bank' asking for money? Hang up and call back on a number you already know, or check with someone close to them. Some families agree on a code word ahead of time for exactly this.
2. Trace the Original Recording
For a clip online, find who posted it first and check the speaker's official channels. Look for a platform AI label or Content Credentials (C2PA), and search for reporting from reputable outlets. A quote that only exists as an anonymous repost deserves suspicion.
3. Check What the Voice Claims
Real or cloned, a voice still has to make claims: a statistic, a quote, a guaranteed return, a 'limited-time' offer. Paste the link into BSmeter to see each claim scored 0-100, with evidence sources for the weakest claim (the 3 weakest on Basic and Premium).
What BSmeter Checks in a Voice Clip
AI voice detection tools listen to how a voice sounds. BSmeter reads what it says: the claims a speaker makes and the tricks used to sell them. Here's what you get when you paste a link.
Transcribes What's Said
Paste a YouTube, TikTok, Instagram Reel, podcast, or audio-file link and BSmeter transcribes the speech. Everything it does from there works on the words a voice speaks, synthetic or not.
Scores Each Claim 0-100
BSmeter pulls out the verifiable claims (numbers, quotes, promises, 'studies show' statements) and gives each one a 0-100 credibility score with its reasoning, so the shakiest parts of a pitch stand out.
Names the Persuasion Moves
Scam scripts and fake endorsements lean on familiar tricks. BSmeter names rhetorical moves like Missing Context, Confidence Mismatch, Anonymous Authority, and Cherry-Picked, and flags logical fallacies, so you can see how a pitch is trying to persuade you.
Searches for Evidence on the Weakest Claim
For the weakest claim (the 3 weakest on Basic and Premium), BSmeter searches for evidence sources you can open and read. Sources can be imperfect and results are AI-generated, so treat them as a starting point, not a final ruling.
Roast, Analyze, or Learn
Pick a mode: Roast is uncensored and joke-first, Analyze is a neutral breakdown, and Learn explains each move and fallacy in plain language.
Extension and Android App
The Chrome and Firefox extension shows results on YouTube, TikTok, and Instagram while you watch, and there's an Android app. A free account gives you 3 analyses a day for videos up to 30 minutes.
Who Uses BSmeter to Check Voice Clips
From families fielding a suspicious call to journalists checking a leaked recording, here's where checking the source and the claims helps.
Protect Against Voice Scams
Got a call from a 'family member' asking for money? Hang up and call back on a number you know. If the same pitch is circulating as a video or audio clip, paste the link into BSmeter to check what it claims.
Verify Celebrity Endorsements
That video of a celebrity endorsing a product might sound real. BSmeter checks the pitch itself: the product claims, the numbers, and the promises, with evidence sources for the weakest claim (the 3 weakest on Basic and Premium).
Journalist Verification
Journalists and researchers can transcribe a recording and pull out the claims that need verifying before publishing. For voice authenticity itself, rely on the original source and expert forensic review.
Political Clips & Ads
AI-voiced campaign ads and debate clips make claims too. BSmeter scores them and names moves like Cherry-Picked or Missing Context, so you can see where a clip stretches the truth.
Podcasts & Long Audio
Paste a podcast or audio-file link to get the claims pulled out and scored: up to 30 minutes on the free plan, 60 on Basic, and 2 hours on Premium.
Learning the Tricks
Learn mode explains each rhetorical move and fallacy in plain language, which makes the next manipulative pitch easier to recognize, whoever or whatever is speaking.
Frequently Asked Questions
Does BSmeter detect AI-generated or cloned voices?
No. BSmeter doesn't analyze the voice signal, so it can't tell you whether a voice is real, AI-generated, or cloned. It doesn't give a voice-authenticity score or identify which voice generator was used. What it does is transcribe the speech, pull out the verifiable claims, give each one a 0-100 credibility score, name rhetorical moves and logical fallacies, and search for evidence sources on the weakest claim (the 3 weakest on Basic and Premium). Its results are AI-generated and can be wrong.
How can I tell if a voice is AI-generated?
Often you can't by ear alone. Warning signs include unnatural pacing, flat or oddly placed emphasis, missing breaths, clipped word endings, and background noise that doesn't fit the setting, but good clones avoid most of them. The checks that hold up are about the source: call the person back on a number you already know, trace a clip to its original upload and the speaker's official accounts, and look for a platform AI label or Content Credentials (C2PA). A dedicated AI voice detector can be one more signal, but its result is a probability, not proof. Whatever the voice is, you can still check what it claims.
What should I do if a call sounds like a family member asking for money?
Hang up and call them back on a number you already have, or contact another family member to check. Don't send money, gift cards, or crypto under time pressure. A family code word for emergencies helps. If you think it was a scam, report it to your local police or your national fraud-reporting agency (in the US, ReportFraud.ftc.gov).
Do I need to upload audio files or can I just paste a link?
BSmeter works from links. Paste a YouTube, TikTok, Instagram Reel, or podcast link, or a direct link to an audio file (for example an .mp3 URL). You'll need a free BSmeter account to run an analysis.
Is BSmeter free?
Yes, there's a free plan: 3 analyses a day for videos up to 30 minutes, with a free account. Basic is $3.99/month (15 analyses a day, videos up to 60 minutes) and Premium is $8.99/month (videos up to 2 hours). See bsmeter.ai/pricing for details.
What's the difference between AI voice detection and deepfake audio detection?
AI voice detection tools try to estimate whether speech was produced by text-to-speech or voice cloning. 'Deepfake audio detection' is often used more broadly, and can also cover real recordings that were edited or spliced to change their meaning. BSmeter does neither. It analyzes the claims in the audio, which matters whether the voice is real or synthetic. For edited clips, finding the full original recording is the most reliable check.
Can BSmeter check live calls or streams for AI voices?
No. BSmeter doesn't detect AI voices at all, and it doesn't work on phone calls. It analyzes recorded videos and audio from a link. If you get an urgent call asking for money, hang up and call the person back on a number you already know.
Don't Get Fooled by AI Voices
Verify the source, call back on a number you know, and check the claims. BSmeter handles the last part: paste a link and see each claim scored 0-100, with evidence sources for the weakest one (the 3 weakest on Basic and Premium). Check a Clip's Claims
