What is OpenVoice?
OpenVoice is a powerful open-source voice cloning model from MyShell.ai, released in early 2024 with a major OpenVoice V2 update later that year. It clones any voice from a short audio reference (just a few seconds) and generates speech in that voice across multiple languages.
What makes OpenVoice special is its granular control — you can adjust emotion, accent, rhythm, pauses, and intonation while preserving the cloned voice timbre. It's released under the MIT license, making it 100% free for commercial use.
Why OpenVoice Is Trending in 2026
Voice cloning has exploded in 2026, and OpenVoice is the top open-source alternative to ElevenLabs and PlayHT. With OpenVoice V2, MyShell improved audio quality, expanded language support to 6 major languages with cross-lingual cloning, and dramatically reduced inference latency.
It's also one of the most ethically-released voice models, with built-in watermarking and clear acceptable-use guidelines.
Key Features and Capabilities
OpenVoice supports instant voice cloning from a single short audio reference — no training required. It generates speech in English, Chinese, Spanish, French, Japanese, and Korean, with cross-lingual cloning so an English speaker can speak fluent Spanish in their own voice.
You also get fine-grained style control over emotion (happy, sad, angry, friendly), accent, rhythm, pauses, and intonation.
Who Should Use OpenVoice?
OpenVoice is built for YouTubers, podcasters, audiobook creators, indie game developers, e-learning platforms, accessibility tool developers, and dubbing professionals who need low-cost, high-quality voice generation.
It's also widely used by AI assistants and chatbot developers wanting custom voices without per-character API fees.
Top Use Cases
Production deployments include audiobook narration, video voiceovers, multilingual dubbing, video game NPC dialogue, accessibility apps for the visually impaired, language learning tools, podcast translations, and virtual assistant voices.
Indie creators love it for translating videos into other languages while keeping their own voice — a feature that previously cost hundreds of dollars per minute on commercial platforms.
Where Can You Use It?
OpenVoice runs locally on any GPU with 4–8 GB VRAM via the official MyShell GitHub repo. Hosted access is available on Hugging Face Spaces, Replicate, and MyShell's own platform (which also offers a free tier).
It integrates with ComfyUI, FastAPI deployments, and is ONNX-exportable for lightweight server deployment.
How to Use OpenVoice (Quick Start)
Clone the repo: git clone https://github.com/myshell-ai/OpenVoice. Run the demo notebook with a 5–30 second voice reference and your target text. The model produces an audio file in the cloned voice within seconds.
For OpenVoice V2, simply pass language and style parameters for cross-lingual generation with emotion control.
When Should You Choose OpenVoice?
Choose OpenVoice when you need unlimited self-hosted voice cloning with full data privacy and zero per-character fees. It's the best free option in 2026 for high-volume voice generation.
For absolute top-tier quality, ElevenLabs and PlayHT still edge out — but they cost $0.30+ per 1,000 characters. OpenVoice is free.
Pricing
OpenVoice is completely free under MIT license. Self-host with zero fees. The hosted MyShell platform offers a generous free tier and pay-as-you-go pricing far below ElevenLabs.
