More details about Whisper model via Azure AI Speech

Question

Hello, I'm trying to integrate the whisper model via Azure AI Speech.

Here are somethings I already know:
https://learn.microsoft.com/en-us/azure/ai-services/speech-service/whisper-overview

• Whisper model via Azure OpenAI Service is available in the following regions:
  • EastUS 2, India South, North Central, Norway East, Sweden Central, and West Europe.
• Whisper model via Azure AI Speech is available in the following regions:
  • Australia East, East US, North Central US, South Central US, Southeast Asia, UK South, and West Europe.
• The quotas are 3 requests per minute for Whisper model via Azure OpenAI Service
• I can try out the Whisper model via Azure AI Speech here: https://speech.microsoft.com/portal/whisperspeechtotext
  • One thing that doesn't make sense to me is that in order to try out the Whisper Model in Azure AI Speech, I need to make a deployment for a Resource for Azure OpenAI Service. But the available regions for Azure OpenAI Service and Azure AI Speech doesn't line up.

So here are the questions I would like to ask

• What is the quotas/limits for the whisper model via Azure AI Speech? I've already checked the following documents which did not have the answer to my question.
  • https://learn.microsoft.com/en-us/azure/ai-services/speech-service/speech-services-quotas-and-limits
• Which region am I supposed to select in order to use the whisper model via Azure AI Speech? I would also greatly appreciate any links where I can learn how to send a REST API request.
