 ## Create a new Azure AI Foundry resource
 
-[Azure AI Foundry portal](https://ai.azure.com/?cid=learnDocs) provides a way to create a new Azure resource with basic,  defaulted, settings.

-# Text to speech avatar overview
+# What is Text to speech avatar?
 
 Text to speech avatar converts text into a digital video of a photorealistic human (either a standard avatar or a [custom text to speech avatar](#custom-text-to-speech-avatar)) speaking with a natural-sounding voice. The text to speech avatar video can be synthesized asynchronously or in real time. Developers can build applications integrated with text to speech avatar through an API, or use a content creation tool on Speech Studio to create video content without coding.
