How multilingual voice cloning works →

Node.js · after installing the SDK
import { VoiceAPI } from '@castreader/voice-api';

const client = new VoiceAPI();
const { audio } = await client.generate({
  voice: 'rowan',
  text: 'Every story deserves to be heard.',
  language: 'en',
  output_format: 'mp3',
});

Explore the full library in the console.

More languages and voice categories are available in the signed-in library. API access is currently by invitation. Choosing a voice does not generate or charge; successful text generation uses your trial characters or API balance.

Open the voice library

Before you choose a voice

Is previewing free?

Playing these saved samples is free and does not use your daily homepage generations or API balance.

Are these all the voices?

This public page features the nine built-in voices. The complete selectable catalog is in the console; private workspace voices are never listed here.

Can I use my own recording?

Yes. Record, upload or invite a speaker with permission. Prepare the clone once, then reuse its workspace voice ID.
