Cannot connect to text-to-speech service.

Question

I am following this text-to-speech guide: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/text-to-speech-avatar/real-time-synthesis-avatar

With a valid key and the correct region, I am getting the error below. Any ideas on why this is happening?

I also check that I was fetching the the ICE server values correctly. So, I don't think that's the issue.

My trial plan still has $199 and 28 days left. I was expecting the call to start the Avatar to be successful.

Answer 1

Have you checked if your Azure subscription has sufficient quotas for the Text-to-Speech Avatar service? Because even with remaining trial credits, there might be specific service limits that could affect functionality. I think you need at least the speech resource to be set to the "Standard S0" pricing tier.
