In this episode of the Colaberry AI Podcast, we dive into VibeVoice — a groundbreaking open-source Text-to-Speech (TTS) model developed by Microsoft. Designed to generate expressive, long-form conversational audio, VibeVoice addresses common limitations in traditional TTS systems through its unique architecture, incorporating ultra-low frame rate continuous speech tokenization and a next-token diffusion framework powered by a Large Language Model. With the ability to synthesize speech for extended durations and manage up to four distinct speakers, primarily in English and Chinese, VibeVoice represents a significant advancement in TTS capabilities. We explore the model's technical details, its potential applications, and the safeguards implemented to promote responsible usage.
