| # 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://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. | |

| ### How to use it locally | |
| ``` | |
| pip install -U WhisperSpeech | |
| ``` | |
| Afterwards: | |
| ``` | |
| from whisperspeech.pipeline import Pipeline | |
| pipe = Pipeline(torch_compile=True) | |
| pipe.generate_to_file("output.wav", "Hello from WhisperSpeech.") | |
| ``` | |
