# Inworld AI

## Integrate Inworld TTS

Each NLX workspace comes equipped with an Inworld integration managed by NLX. You can access it in the [API channel setup ](https://docs.nlx.ai/platform/nlx-platform-guide/ai-applications/deployment/managing-channels/creating-an-api-channel#access-api-channel)of your application. 

Connecting your own instance is only necessary if you:

* Prefer to use your own API keys
* Need custom voice cloning, pronunciations, and text normalization

To create a custom integration with *Inworld*, begin by selecting *Resources* from your workspace menu and choosing *Integrations*:

1. Click *+ Add integration* > Choose *Inworld* from the *Type* dropdown
2. Provide your integration a name
3. Enter the API key from your Inworld Portal. Don't have an account? [Sign up here](https://platform.inworld.ai/login)
4. Click *Create integration*
