Detect AI-Generated Voices in Seconds

Is that voice real or AI-generated? BSmeter analyzes audio from videos, podcasts, and recordings to detect synthetic speech, cloned voices, and deepfake audio with 94%+ accuracy. A free Chrome extension is available, and no sign-up is required. Over 4,800 videos analyzed and counting.

What you get

AI Voice Detection Engine: BSmeter analyzes audio tracks from any video or podcast to identify AI-generated or cloned voices. Using spectral analysis and acoustic fingerprinting, it flags synthetic speech patterns, unnatural emphasis, robotic cadence, and artifacts common to ElevenLabs, OpenAI TTS, and other AI voice generators.
Voice Cloning Identification: Voice cloning scams are on the rise — scammers clone a person's voice from 30 seconds of audio and call family members faking emergencies. BSmeter's voice fingerprinting compares audio samples against known patterns, helping you verify whether a voice recording is authentic or synthetically generated.
Deepfake Audio Analysis: Beyond basic voice detection, BSmeter analyzes the full audio spectrum for deepfake artifacts — inconsistent background noise, unnatural breath patterns, splicing artifacts, and frequency anomalies. Whether it's a deepfake robocall, a fake celebrity endorsement, or a manipulated interview, you get a detailed credibility score.
Real-Time Credibility Scoring: Every video or audio clip gets a 0-100 credibility score based on voice authenticity, source verification, and claim analysis. The AI voice detection component feeds into the overall score, so you know at a glance whether a recording is trustworthy — perfect for journalists, fact-checkers, and concerned consumers.
Multilingual Voice Detection: AI voice cloning works across languages — and so does BSmeter. Supporting 8+ languages including English, Spanish, Mandarin, Arabic, Hindi, French, German, and Portuguese, BSmeter's voice detection engine identifies synthetic speech regardless of the language spoken.
Shareable Voice Analysis Reports: Every voice analysis generates a shareable report showing the voice authenticity score, detected AI artifacts, spectral analysis charts, and recommended actions. Share with journalists, law enforcement, or family members to help combat voice cloning scams and misinformation.

Frequently asked questions

How accurate is BSmeter's AI voice detection?: BSmeter's voice detection engine achieves industry-leading accuracy by combining multiple detection methods: spectral analysis (identifying synthetic frequency artifacts), acoustic fingerprinting (matching against known AI voice signatures), deep learning classification (trained on millions of real and synthetic samples), and behavioral analysis (detecting unnatural speech patterns). In internal benchmarks, BSmeter correctly identifies AI-generated voices with 94%+ accuracy across 10+ AI speech engines.
Can BSmeter detect any AI voice generator?: BSmeter is trained to detect voices from the most popular AI speech engines including ElevenLabs, OpenAI TTS (including the new GPT-4o voice mode), Google Text-to-Speech, Amazon Polly, Microsoft Azure Speech, PlayHT, Murf AI, Descript Overdub, Respeecher, and more. As new AI voice generators emerge, BSmeter's detection models are continuously updated.
Do I need to upload audio files or can I just paste a link?: Both options work. Paste any YouTube, TikTok, Instagram, or podcast URL and BSmeter automatically extracts and analyzes the audio. You can also upload audio files directly (MP3, WAV, M4A, OGG supported up to 50MB). No sign-up required for the first analysis daily.
Is BSmeter's voice detection free?: Yes! BSmeter offers 1 free voice detection analysis every day, resetting at midnight. For unlimited analyses, advanced features (voice fingerprint database, batch processing, API access), and priority processing, check our Pro plan at bsmeter.ai/pricing.
What's the difference between AI voice detection and deepfake audio detection?: AI voice detection specifically identifies whether a voice was generated by AI text-to-speech or voice cloning systems. Deepfake audio detection is broader — it also detects manipulated real audio (spliced, pitch-shifted, or re-sequenced recordings), synthetic background sounds, and AI-generated music or sound effects. BSmeter does both, giving you a complete audio authenticity analysis.
Can BSmeter detect AI voice in live calls or streams?: BSmeter works best with recorded content (videos, podcasts, uploaded audio) where it can perform thorough spectral analysis. For live streams, BSmeter can analyze clips and segments from the recording. We're working on real-time voice detection for live calls — check our Chrome extension for the latest updates.
Does BSmeter store the audio I analyze?: Audio analysis is processed securely and audio files are not stored permanently. Analysis results (credibility scores and detection reports) are saved to your account if you sign in. If you use BSmeter without signing in (free tier), analysis data is ephemeral and not retained after your session.
