🚿 Streaming

Stream audio in real-time, as it's being generated.

const audioStream = await elevenlabs.generate({
  stream: true,
  voice: "Bella",
  text: "This is a... streaming voice",
  model_id: "eleven_multilingual_v2"
});

stream(audioStream)

Retries

This Node SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long as the request is deemed retriable and the number of retry attempts has not grown larger than the configured retry limit (default: 2).

A request is deemed retriable when any of the following HTTP status codes is returned:

408 (Timeout)
409 (Conflict)
429 (Too Many Requests)
5XX (Internal Server Errors)

Use the maxRetries request option to configure this behavior.

const response = await elevenlabs.voices.getAll({
  maxRetries: 0 // override maxRetries at the request level
});

Timeouts

The SDK defaults to a 60 second timout. Use the timeoutInSeconds option to configure this behavior.

const response = elevenlabs.voices.getAll({
  timeoutInSeconds: 30 // override timeout to 30s
});

Runtime compatiblity

The SDK defaults to node-fetch but will use the global fetch client if present. The SDK works in the following runtimes:

The following runtimes are supported:

Node.js 15+
Vercel
Cloudflare Workers
Deno v1.25+
Bun 1.0+

Customizing Fetch client

The SDK provides a way for you to customize the underlying HTTP client / Fetch function. If you're running in an unsupported environment, this provides a way for you to break the glass and ensure the SDK works.

import { ElevenLabsClient } from "elevenlabs";

const elevenlabs = new ElevenLabsClient({
  apiKey: "...",
  fetcher: // provide your implementation here
});

Elevenlabs Namespace

All of the ElevenLabs models are nested within the ElevenLabs namespace.

Languages Supported

We support 29 languages and 100+ accents. Explore all languages.

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
