Unlike traditional TTS models, VibeVoice excels in generating up to **90 minutes of audio**, supports **up to four distinct AI-generated speakers**, and handles natural conversation flow and speaker consistency.\n\nTwo versions are currently available for testing: a **1.5 billion parameter model**, which supports longer content and a **64k context window**, and a **7 billion parameter model**, offering higher quality but with a **shorter 45-minute audio limit** and **32k context window**. A **lighter 0.5 billion parameter** version for real-time audio is coming soon. The models run on relatively moderate VRAM — from 7GB to 18GB depending on size — making local usage feasible.\n\nVibeVoice supports both **English and Mandarin**, with potential expansion to other languages. It can generate multi-speaker dialogue and express emotions but isn’t yet skilled at singing. Future plans include **voice cloning** capabilities.

Publishers can choose between an end-to-end service managed by Audible or a self-service model for creating audiobooks.\n\nAdditionally, Audible plans to introduce AI-powered translation tools later this year in beta. These will translate English-language books into Spanish, French, Italian, and German, using either text-to-text or speech-to-speech methods. The latter retains the original narrator’s voice and style. Publishers can manually review the translations or opt for professional linguistic review.\n\nAudible's move aims to expand access to audiobooks globally while leveraging Amazon’s AI advancements.
