What is VibeVoice?
VibeVoice is a multi-speaker dialogue generation model that produces conversational audio from script-format input with up to 4 distinct voices. Users write dialogue in script format using speaker labels, and the model generates a natural-sounding conversation with distinct voices, automatic speaker assignment, and natural conversational flow. With per-minute billing at approximately $0.04 per minute ($0.0007 per second), it is extremely affordable for dialogue content. The model includes 8 built-in voice presets: 5 English speakers (Alice, Carter, Frank, Maya, Mary) and 3 Chinese speakers (Bowen, Xinran, Anchen). The script format input is intuitive for content creators familiar with screenplay or dialogue writing. Compared to generating separate TTS tracks per speaker and mixing them together, VibeVoice handles the entire conversation in a single pass with natural turn-taking and conversational dynamics. Against other TTS models that handle only single speakers, the multi-speaker capability is a distinct advantage for dialogue content. Best suited for podcast-style conversations, dialogue generation, multi-character audiobooks, and interview-format content where natural multi-speaker dialogue is needed. Available on FairStack at infrastructure cost plus a 20% platform fee.
