Two Powerful Models, Infinite Possibilities
VibeTTS brings you the best of open-source text-to-speech technology, making advanced AI voices accessible to everyone. Our platform currently features two production-ready models, each with unique strengths for different use cases.
Born from frustration with limited AI dubbing controls (learn more about our story), VibeTTS was created to unlock the full potential of sophisticated TTS models like Toucan - giving you the advanced prosody controls and language coverage that was previously unavailable.
Currently Available Models
| Model | Best For | Language Support | Voice Cloning | Key Strength |
|---|---|---|---|---|
| Toucan | Global reach & prosody control | 7,000+ | Yes | Universal language powerhouse |
| Kokoro | Highest audio quality & naturalness | 9 languages | No | Exceptional audio quality |
Meet Our Models
Toucan: Breaking Down Language Barriers
Imagine having access to voices in over 7,000 languages - from major world languages to regional dialects and even endangered languages. That's the power of Toucan, our universal language powerhouse developed by the University of Stuttgart.
What makes Toucan truly special isn't just its incredible language range, but its advanced prosody control capabilities. Every single inference on our platform, regardless of which model you choose, gets processed by Toucan for prosody extraction. This means you can fine-tune the pitch, energy, and duration of every sound - giving you the kind of control that was previously only available to professional voice directors.
Why Choose Toucan:
- When you need to reach a global audience across multiple languages
- For projects requiring precise control over speech delivery and expression
- When you want to clone voices while maintaining that control across 7,000+ languages
- For extracting and editing prosody from existing audio recordings

Kokoro: Where Quality Meets Naturalness
If your priority is the most natural, human-like voice possible, Kokoro is your answer. Developed by hexgrad, this model focuses on delivering exceptional audio quality that sounds genuinely human - the kind of voice quality that keeps listeners engaged through long-form content.
While Kokoro supports 9 languages compared to Toucan's thousands, it makes up for this with unmatched naturalness in those languages. It's the model you choose when you want your audience to forget they're listening to AI-generated speech.
Why Choose Kokoro:
- For audiobooks, podcasts, and long-form content where naturalness is crucial
- When you need broadcast-quality voice output
- For professional narrations where clarity and human-like delivery matter most
- When working within its 9 supported languages and quality is the top priority

Coming Soon: Expanding Our Model Family
We're constantly working to bring you more powerful TTS capabilities. Here's what's in development:
Orpheus: The Expressive Storyteller ⏳
Orpheus will bring emotional depth to voice generation with emotional tags like [laugh], [sigh], and [gasp]. This model from Canopy AI will be perfect for creative applications requiring expressive, character-driven voices.
Planned features: Emotional tags, LLama-based architecture, multi-language support
Chatterbox: The Voice Cloning Specialist ⏳
When it launches, Chatterbox will offer specialized voice cloning capabilities with a focus on English-language fidelity. Developed by Resemble AI, it will excel at creating high-quality digital voice replicas.
Planned features: High-fidelity voice cloning, English specialization, emotion control
Making the Right Choice for Your Project
Choosing between our two models comes down to your specific priorities:
Choose Toucan when:
- You need to reach audiences in multiple languages (especially beyond the major 9)
- Precise control over prosody and speech delivery is important
- You want to clone voices while maintaining that control
- Your project involves extracting and editing prosody from existing recordings
Choose Kokoro when:
- Audio quality and naturalness are your top priorities
- You're working within its 9 supported languages
- Long-form content like audiobooks or podcasts where listener comfort matters
- Professional narrations where broadcast-quality output is essential
Real Performance: What to Expect
Both models are production-ready and deliver professional results, but here's what you can actually expect:
Generation Speed: Typically 1.5-2 seconds per inference thanks to our auto-inference feature that automatically regenerates audio when you make changes.
Voice Control: With Toucan's prosody processing, you get granular control over pitch, energy, and duration of every speech sound - whether you're using Toucan or Kokoro as your base model.
Language Coverage: Toucan's 7,000+ language support isn't marketing fluff - it genuinely covers major world languages, regional dialects, and endangered languages with authentic pronunciation patterns.
Quality Consistency: Both models maintain stable quality across different text lengths and content types, though longer passages benefit from the natural breathing patterns both models incorporate.
