What Is OpenVoice? OpenVoice 是什么？
OpenVoice is an open-source project with 37k+ GitHub stars. Licensed under CC BY-NC 4.0. Versatile instant voice cloning by MyShell AI
The project focuses on voice, cloning, tts use cases and is designed as a ready-to-use application—you can deploy or run it directly without writing integration code.
Source code is available at github.com/myshell-ai/OpenVoice. With 37k+ GitHub stars, it ranks among the most battle-tested open-source tools in this space—meaning most common use cases are well-documented with community solutions available.
Podcast producers can create consistent host voice variations across episodes using just 5-second audio clips, something that traditionally required professional voice actors. Unlike ElevenLabs' API-first approach, OpenVoice's 37k+ GitHub stars reflect its accessibility for developers who need instant cloning without subscription costs. However, teams requiring multilingual cloning with perfect accent matching should explore alternatives, as OpenVoice's strength lies in single-language fidelity.
