1. Tutorial Introduction

VibeVoice-1.5B is a new text-to-speech (TTS) model released by Microsoft in August 2025. It generates expressive, long-form, multi-speaker conversational audio, such as podcasts. This model leverages innovative continuous speech tokenization technology and a next-generation token diffusion framework, combined with a large language model (LLM), to efficiently process long audio sequences while maintaining high fidelity. VibeVoice can synthesize up to 90 minutes of speech, supporting up to four different speakers. This model breaks through the limitations of traditional TTS systems and provides new possibilities for natural conversation and emotional expression.

The computing resources used in this tutorial are a single RTX 4090 card.
