Detect AI Voice Cloning & Synthetic Audio
Upload any video or audio content. ForgeSpy's audio model analyses spectral patterns, prosody, and acoustic artefacts to detect voice cloning, text-to-speech synthesis, and AI-generated narration — completely independently of the visual analysis.

How it works
Simple. Fast. Accurate.
Upload a video or audio file
Upload a video containing speech, or a direct audio recording. Paste a social media link and we handle extraction.
Audio model runs in parallel
While video frames are analysed visually, a dedicated audio model runs simultaneously — checking the voice track independently.
Separate audio verdict
Receive a confidence score specifically for the audio track — e.g. "96% — Voice Cloning Detected".
Features
Everything you need to verify content
Voice cloning detection
We detect AI voice clones made from real people's voices — even highly convincing ones from tools like ElevenLabs.
Text-to-speech detection
Identify when an AI text-to-speech engine has been used instead of a real human narrator.
Spectral analysis
Our model analyses the audio spectrum for subtle patterns that distinguish real human speech from AI synthesis.
Independent analysis
Audio analysis runs in parallel to — not dependent on — the visual scan, giving you complete bi-directional detection.
Confidence scoring
Every audio verdict includes a 0–100% confidence score so you understand the certainty of the detection.
Mobile app
Check audio on the go with the ForgeSpy iOS and Android app.

Frequently asked questions
What is voice cloning and can ForgeSpy detect it?
Voice cloning uses AI to synthesise a convincing replica of a person's voice from audio samples. ForgeSpy's audio detection model analyses spectral patterns, prosody, and acoustic artefacts to flag AI-generated audio.
Can ForgeSpy detect AI narration in videos?
Yes. When you scan a video, ForgeSpy runs a separate audio analysis in parallel to check whether the narration or speech is AI-generated — independently of the visual analysis.
Is the AI audio detector free to use?
Audio analysis is included in every video scan. You receive 5 free credits on sign-up — no card required.
Can ForgeSpy detect AI voices from ElevenLabs or similar tools?
ForgeSpy detects acoustic and spectral signatures common to AI voice synthesis including ElevenLabs, Murf, and similar text-to-speech services.
