Breaking Down Language Barriers
VibeTTS is powered by Toucan, a state-of-the-art multilingual text-to-speech model developed by the University of Stuttgart. With support for over 7,000 languages, Toucan enables you to reach audiences across the globe - from major world languages to regional dialects and even endangered languages.
Born from frustration with limited AI dubbing controls (learn more about our story), VibeTTS was created to unlock the full potential of Toucan - giving you the advanced prosody controls and language coverage that was previously unavailable.

Advanced Prosody Control
What makes Toucan truly special isn't just its incredible language range, but its advanced prosody control capabilities. 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.
Imagine being able to direct a voice actor with the precision of a professional voice director - adjusting not just how fast they speak, but the creativity in their delivery, the energy they put into each word, even the length of natural pauses. That's exactly what VibeTTS gives you.
Key Prosody Features
- Prosody Creativity: Control how expressive and varied the speech patterns are
- Duration Scaling: Adjust overall speaking pace without affecting naturalness
- Pitch Variance: Control the melodic variation in speech
- Energy Variance: Adjust emphasis and intensity patterns
- Pause Duration: Fine-tune natural pauses between phrases
- Loudness Control: Set the overall volume level
Voice Cloning
Toucan's voice cloning capabilities allow you to create custom voices from short audio samples. Simply upload a recording and Toucan will learn the voice characteristics, enabling you to generate new speech in that voice across any of its 7,000+ supported languages.
Voice Cloning Use Cases:
- Create consistent brand voices for your content
- Preserve voices for accessibility or memorial purposes
- Generate multilingual content in a single consistent voice
- Build custom voice personas for applications
