Vyonica SDK

Clone any voice from a single reference WAV — in a few lines of TypeScript.

Get started API reference

What you can do

One-liner clone

Pass a reference WAV and the text to synthesize. Get a buffer back.

Manual job flow

Submit, poll, and download separately when you need finer control over a fleet of jobs.

Minute-based quotas

Track how many voice minutes are left on your API key with client.getUsage().

Typed errors

AuthenticationError, QuotaExceededError, JobFailedError, JobTimeoutError — discriminate cleanly.

import { VyonicaClient } from 'vyonica';
import fs from 'fs';

const client = new VyonicaClient({ apiKey: 'nvsk_...' });
const audio = await client.clone(
  fs.readFileSync('reference.wav'),
  { text: 'Hello world', language: 'en' }
);
fs.writeFileSync('output.wav', audio);
