Unique Advantages

VibeVoice stands out by leveraging the open-source VibeVoice framework, developed by Microsoft Research, to deliver capabilities that redefine what's possible with free, accessible TTS.

• Unmatched Long-Form & Multi-Speaker Capability: Unlike most online TTS services, VibeVoice.cc is specifically engineered for extended, multi-speaker content. It supports up to 90 minutes of continuous audio with up to four distinct, consistently identified speakers, making it uniquely suited for complex narrative and conversational projects.

• Industry-Leading Voice Quality: Independent human evaluation scores consistently rank VibeVoice's output higher in realism and richness than prominent commercial services like ElevenLabs v3 Alpha and Google Gemini 2.5 Pro for its specialized long-form, multi-speaker capabilities. This demonstrates its advanced ability to produce natural and engaging speech.

• Open-Source Core & Accessibility: While the VibeVoice.cc online service is free and user-friendly, its underlying VibeVoice framework is open-source (MIT licensed). This provides unparalleled transparency and flexibility for developers and researchers who wish to run it locally, extend its capabilities, or integrate it into their own projects.

FAQ

• How long can VibeVoice.cc generate speech? The service supports generating up to 90 minutes of continuous audio using the 1.5B model, while a larger 7B model (available for local deployment) supports about 45 minutes with even higher naturalness. Both maintain coherent dialogue throughout the entire generation.

• How many speakers can I include in one audio? VibeVoice natively supports up to four distinct speakers within a single audio generation. You can assign specific text scripts to each speaker, and the system maintains consistent voice characteristics and role identity throughout the conversation.

• Which languages does VibeVoice.cc support? VibeVoice is primarily optimized and trained for English and Chinese, delivering the highest quality in these languages. While it may produce outputs in other languages, cross-lingual capabilities beyond English and Chinese are considered experimental and may yield unstable results.

• Can I use VibeVoice.cc for commercial projects? While the underlying VibeVoice framework is MIT licensed, the research team explicitly recommends VibeVoice.cc primarily for research and development use. For commercial deployment, additional testing, robust safeguards, and clear disclosure of AI-generated content are strongly advised due to the potential risks of misuse.
