MIT, MyShell.ai, and Tsinghua University researchers have developed OpenVoice, an open-source instant voice cloning method. It overcomes voice cloning challenges by enabling flexible voice style control and zero-shot cross-lingual cloning. OpenVoice can replicate a voice, generate speech in multiple languages, control voice styles, and accurately clone the reference speaker’s tone color.
Challenges in Voice Cloning
1) Flexible Voice Style Control
Many Instant Voice Cloning (IVC) approaches struggle to manipulate voice styles precisely, including emotions, accents, rhythm, pauses, and intonation. OpenVoice provides adaptable manipulation of these critical style elements, enabling contextually authentic speech and dynamic conversations.
2) Zero-Shot Cross-Lingual Voice Cloning
IVC approaches often require extensive multi-lingual datasets for all languages. OpenVoice achieves zero-shot cross-lingual voice cloning for languages not included in the training set, without requiring extensive data for those languages.
OpenVoice: Instant Voice Cloning
A collaboration between MIT, MyShell.ai, and Tsinghua University researchers has resulted in OpenVoice, an open-source method for instant voice cloning.
OpenVoice achieves versatile instant voice cloning by replicating the voice of a reference speaker and generating speech in multiple languages. The approach enables granular control over voice styles, including emotion, accent, rhythm, pauses, and intonation, while accurately cloning the tone color of the reference speaker.
Technical Approach
OpenVoice decouples voice components, independently generating language, tone color, and other voice features. The tone color cloning in OpenVoice is achieved through a structurally similar tone color converter, training the base speaker TTS model using audio samples from various languages.
Value and Practical Solutions
OpenVoice showcases impressive capabilities in instant voice cloning, surpassing prior methods in flexibility regarding voice styles and languages. The approach is computationally efficient, costing significantly less than commercially available APIs.
