Hi GenixPRO
Welcome to Microsoft Q&A Forum, thank you for posting your query here!
Currently, audio-video chat is not available in Azure OpenAI. The GPT-4o family of models supports text, audio, and image inputs but does not yet support audio-video chat functionality. There is no ETA for when this feature might be introduced. Microsoft plans to implement this in the future, so we recommend keeping an eye on the OpenAI what's-new for updates.

Thank You.
