Introducing WaveSpeedAI Vibevoice on WaveSpeedAI

Meet VibeVoice: Long-Form, Multi-Speaker Speech Generation Has Arrived on WaveSpeedAI

Creating podcast-quality audio from text has never been easier. Today, we’re thrilled to announce that VibeVoice is now available on WaveSpeedAI—bringing you the power to generate natural, expressive, long-form speech with support for multiple speakers in a single request.

Whether you’re producing podcasts, audiobooks, educational content, or scripted dialogues, VibeVoice transforms your text into professional-grade audio that sounds like real conversations, not robotic readouts.

What is VibeVoice?

VibeVoice is an advanced text-to-speech model built on a next-token diffusion framework that combines the contextual understanding of a large language model with high-fidelity acoustic generation. The result? Speech that captures natural pacing, conversational rhythm, and authentic turn-taking between speakers.

What sets VibeVoice apart from traditional TTS solutions is its ability to handle extended content—up to 90 minutes of audio in a single generation—while maintaining speaker consistency and natural dialogue flow throughout. This makes it exceptionally well-suited for content that goes beyond quick voice snippets.

The model uses continuous speech tokenizers operating at an ultra-low frame rate of 7.5 Hz, which preserves audio fidelity while dramatically improving computational efficiency for processing long sequences. This architectural innovation enables VibeVoice to handle 64K context windows, supporting the extended audio lengths that podcast creators and audiobook producers need.

Key Features

Long-Form Speech Generation: Generate up to 90 minutes of coherent speech in a single request—perfect for full podcast episodes, audiobook chapters, and lecture-style narration
Multi-Speaker Dialogue: Support for up to 4 distinct speakers in one generation, enabling interviews, panel discussions, and scripted conversations without stitching multiple outputs together
Consistent Speaker Identity: Each speaker maintains their unique voice characteristics and conversational style throughout the entire script, even across lengthy content
Natural Conversational Delivery: Optimized for dialogue-like speech with proper turn-taking, natural pauses, and authentic rhythm—not sentence-by-sentence robotic output
Transcript-Based Input: Works naturally with script formats, supporting speaker tags (S1:, S2:, etc.) for clear multi-speaker direction
English and Chinese Support: Full language support for two of the world’s most widely spoken languages

Real-World Use Cases

Podcast Production

Transform your show scripts into fully produced audio episodes. VibeVoice excels at the back-and-forth dynamics of interview-style podcasts, making it possible to generate complete episodes with distinct host and guest voices. Structure your transcript with intro, main segments, and outro, and let the model handle the natural conversational flow.

Audiobook Narration

Long-form coherence is critical for audiobooks, and VibeVoice delivers. Whether you’re producing a single-narrator experience or a full-cast audio drama with multiple characters, the model maintains consistent voice identity and pacing throughout chapter-length content.

Educational Content

Create engaging lecture content, tutorial narrations, or training materials. The natural delivery style keeps listeners engaged during extended educational sessions, while multi-speaker support enables Q&A formats or conversational teaching approaches.

Content Localization

With support for both English and Chinese, VibeVoice enables content creators to produce audio versions of their content for different markets, maintaining natural speech patterns in each language.

Scripted Dialogue for Media

Game developers, animation studios, and video producers can use VibeVoice to generate dialogue for prototyping, temporary voice tracks, or even final production—with up to four distinct characters speaking naturally in a single generation.

Getting Started on WaveSpeedAI

Using VibeVoice on WaveSpeedAI is straightforward:

Navigate to the Model: Visit VibeVoice on WaveSpeedAI to access the model’s playground

Pro Tips for Best Results

Write like a transcript: Short utterances, clear turn-taking, and punctuation that reflects how you want lines spoken
Tag speakers consistently: Use clear patterns like S1:, S2: throughout your script
Avoid overlapping dialogue: Keep speaker turns separate for clean output
Use direction cues sparingly: Brief cues like (pause) may help, but results vary

Here’s an example of well-formatted input:

S1: Welcome back to the show. Today we're diving into AI voice generation.
