Voice Design, an innovative feature by ElevenLabs, is now accessible via API, enabling users to create unique voices from prompts by specifying characteristics such as age, accent, and tone, or even designing fantastical voices for characters like ogres and pirates. This feature includes two API endpoints: one for generating three unique voice previews from text prompts and another for saving these previews to a library. To showcase its capabilities, ElevenLabs developed xtovoice.com, a demo project that generates a unique voice and avatar based on a user's X (formerly Twitter) profile. Users can explore this open-source project and other articles by the ElevenLabs team to understand how to leverage these tools for creating high-quality AI audio experiences.
