This demo is running on CPU 🐢. Offered by Sylvain <a href='https://twitter.com/fffiloni' target='_blank'>@fffiloni</a> • <img id='visitor-badge' alt='visitor badge' src='https://visitor-badge.glitch.me/badge?page_id=gradio-blocks.whisper-to-stable-diffusion' style='display: inline-block' /><br />
Record an audio description of an image, stop recording, then hit the Submit button to get 2 images from Stable Diffusion.<br />
Your audio will be translated to English through OpenAI's Whisper, then sent as a prompt to Stable Diffusion.
Try it in French ! ;)<br />

Whisper is a general-purpose speech recognition model. <br />
It is trained on a large dataset of diverse audio and is also a multi-task model that can perform<br />multilingual speech recognition as well as speech translation and language identification.<br />
