Run VITS based text-to-speech in the browser powered by the ONNX Runtime
A big shout-out goes to Rhasspy Piper, who open-sourced all the currently available models (MIT License) and to @jozefchutka who came up with the wasm build steps.
Usage
First of all, you need to install the library:
npm i --save @diffusionstudio/vits-web
Then you're able to import the library like this (ES only)
import * as tts from '@diffusionstudio/vits-web';
Now you can start synthesizing speech!
const wav = await tts.predict({
text: "Text to speech in the browser is amazing!",
voiceId: 'en_US-hfc_female-medium',
});
const audio = new Audio();
audio.src = URL.createObjectURL(wav);
audio.play();
With the initial run of the predict function you will download the model which will then be stored in your Origin private file system. You can also do this manually in advance (recommended), as follows:
await tts.download('en_US-hfc_female-medium', (progress) => {
console.log(`Downloading ${progress.url} - ${Math.round(progress.loaded * 100 / progress.total)}%`);
});
The predict function also accepts a download progress callback as the second argument (tts.predict(..., console.log)
).
If you want to know which models have already been stored, do the following
console.log(await tts.stored());
You can remove models from opfs by calling
await tts.remove('en_US-hfc_female-medium');
await tts.flush();
And last but not least use this snippet if you would like to retrieve all available voices:
console.log(await tts.voices());
That's it! Happy coding :)
