AI Voice Detector
Overview
The AI Voice Detector serves as a forensic instrument for verifying the authenticity of spoken audio. Users can upload audio files (MP3, WAV, M4A, WebM up to 25MB), paste URLs, or record directly from their browser. The system processes the audio in approximately half a second, analyzing it against signatures from over 24 major voice synthesis models, including ElevenLabs, Resemble, PlayHT, and OpenAI TTS. It returns a probability score indicating whether the audio is likely fabricated and, if recognized, attributes it to a specific generator.
Each verdict comes with a permanent URL and an APA-style citation, making it suitable for journalistic or legal evidence. The platform also offers a REST API for integration into existing workflows, allowing developers to programmatically submit audio and receive verdicts. A Chrome extension provides quick detection directly from web pages. The model is regularly retrained monthly to incorporate new AI voice generators, ensuring its accuracy and relevance.
