# How to configure basic settings

Basic Settings define how your AI agent **sounds, thinks, and communicates** during a call.

These are the **core configuration controls** that directly impact:

* Voice quality and experience
* Response speed and intelligence
* Language understanding and accuracy
* Overall conversation flow

👉 Incorrect setup here can lead to robotic voice, slow responses, or poor user experience.
