Using a Knowledge Base with your voice AI assistant offers several benefits:
* **Improved accuracy**: By integrating custom documents into your assistant, you can ensure that it provides accurate and up-to-date information to users.
* **Enhanced capabilities**: A Knowledge Base enables your assistant to answer complex queries and provide detailed responses to user inquiries.
* **Customization**: With a Knowledge Base, you can tailor your assistant's responses to specific domains or topics, making it more effective and informative.
