Aivoicedetector is a tool designed to determine whether an audio clip contains AI-generated or human speech, delivering a citable verdict in under half a second. It addresses the challenge of verifying spoken authenticity in an era of advanced voice synthesis, serving users who need reliable evidence about the origins of audio content. The platform is used by newsrooms, legal investigators, compliance teams, and individuals seeking to authenticate voice recordings, and its methodology is cited in multiple media outlets and legal cases.
The service allows users to submit audio files by dragging and dropping, pasting a URL, or recording directly from the browser, accepting formats such as MP3, WAV, M4A, and WebM up to 25MB. Aivoicedetector analyzes the clip against over 24 voice synthesis models, including those from ElevenLabs, Resemble, PlayHT, OpenAI, and others, providing a probability score and, when possible, naming the specific generator. Each analysis yields a permanent, citable verdict with an APA-style citation, a confidence score, and a link to the methodology, supporting use in editorial review, legal proceedings, and compliance audits. Users can save verdicts to a private dossier, create audit logs, share dossiers with teams, and export results to CSV or PDF.
The platform offers a REST API, enabling integration into other systems with JSON input and output and webhooks for asynchronous jobs. A Chrome extension is also available, allowing users to right-click on audio in any browser tab to receive a verdict and citation. The tool is accessible without requiring an account for single verdicts, while sign-in is needed to save or cite results externally. Aivoicedetector maintains a free tier, permitting up to 50 verdicts per month without requiring a credit card. The detection model is retrained monthly, covers new voice synthesis systems as they emerge, and publishes its methodology for transparency. Audio retention is limited to 24 hours, after which only a fingerprint is kept.
Since its launch in January 2023, Aivoicedetector has analyzed over 90,000 audio clips for more than 48,000 users across 84 countries. The tool is developed and maintained by a team of researchers and engineers based in London.
In the AI Tools space, Aivoicedetector takes a focused approach. It detects whether an audio clip was generated by an AI voice or a real human voice. It is built as a B2B product for content creators and audio professionals. There is a free tier, and paid plans start at $9. The product ships for the web and embeddable surfaces.
