What it is

OpenVoice is an open-source tool for instant voice cloning developed by MIT and MyShell, providing a powerful audio foundation model for developers to integrate into their applications.

OpenVoice stands out as an open-source solution with a focus on providing developers with instant voice cloning capabilities, offering flexibility and customization options not commonly found in other tools.
