# Text-to-speech providers

*TTS (text-to-speech)* is a technology that converts written text into spoken audio using synthetic human-like voices. Applications with TTS capabilities use advanced AI and speech synthesis models to read generated or predefined messages aloud in a natural-sounding way. 

You may use the built-in TTS providers available in your workspace or integrate your own instance of Inworld AI to add voice functionality to your applications.

### Built-in

Every workspace comes equipped with NLX-managed TTS providers. Use these managed providers for the fastest path to voice; no keys or extra setup required.

You may select any of these directly in your app’s [API channel voice configuration](/platform/nlx-platform-guide/ai-applications/deployment/managing-channels/creating-an-api-channel.md) to give your application a natural, human-like voice.
