AI Voice Detector is a tool designed to determine the source of an audio file, whether human or AI-generated. This tool protects users against audio manipulation and AI voice frauds. With the rise of sophisticated AI voices, distinguishing between AI generated and human voices has become difficult. AI Voice Detector provides the solution for this, including a browser extension that can be used across various platforms like YouTube, WhatsApp, Tiktok, Zoom and Google Meet. Users can also upload the required audio file directly for detection. Furthermore, this tool offers features to improve detection accuracy, such as an integrated background noise removal utility. The tool is not limited by the duration of the audio file, being able to detect the source in short audios of less than seven seconds. Alongside the browser extension, AI Voice Detector also offers an API for businesses to integrate into their work environment and confirm the authenticity of received audio messages, calls, or meetings. Thus, the tool is useful in individual and business contexts to counteract potentially significant financial losses stemming from AI voice scams.
