+# Welcome to Collabora's WhisperSpeech
+
+WhisperSpeech is an Open Source text-to-speech system built by Collabora and LAION by inverting Whisper.
+The model is fully open and you can run it on your local hardware. It's like **Stable Diffusion but for speech**
+– both powerful and easily customizable.
+
+[You can contribute to WhisperSpeech on Github.](https://github.com/collabora/WhisperSpeech)
+You can also join the discussion on Discord [![](https://dcbadge.vercel.app/api/server/FANw4rHD5E)](https://discord.gg/FANw4rHD5E)
+
+Huge thanks to [Tonic](https://huggingface.co/Tonic) who helped build this Space for WhisperSpeech.
+
+### How to Use It
+
+Write you text in the box, you can use language tags (`<en>` or `<pl>`) to create multilingual speech.
+Optionally you can upload a speech sample or give it a file URL to clone an existing voice. Check out the
+examples at the bottom of the page for inspiration.
