VibeVoice 7B
VibeVoice 7B is Microsoft's higher-capacity text-to-speech model offering expressive, high-quality voice generation. At 7 billion parameters, it occupies the upper tier of the VibeVoice line, providing noticeably richer prosody, more natural pacing, and greater expressiveness compared to the 1.5B variant, at the cost of higher compute requirements.
Microsoft positions VibeVoice 7B for production deployments where voice quality is a differentiating factor — customer-facing applications, premium content creation, and enterprise voice experiences. It is suited for organizations already in the Microsoft ecosystem who want high-quality TTS without routing through a third-party voice API.
