VibeVoice
VibeVoice is an open-source voice AI framework providing speech recognition and text-to-speech models.
VibeVoice is a family of open-source frontier voice AI models that includes both Text-to-Speech and Automatic Speech Recognition models. A core innovation uses continuous speech tokenizers operating at a low frame rate to preserve audio fidelity. It employs a next-token diffusion framework using a Large Language Model to understand dialogue flow. The platform handles long-form audio transcription and multi-speaker speech generation. It supports streaming inputs and multiple languages across various open-source models.
