Hello @Kaka Lam
Thanks for reaching out to us, now Whisper is in public preview in Azure AI Speech, which is as you mentioned -- Azure Speech Service.
Azure AI Speech now supports OpenAI's Whisper model via the batch transcription API. To learn more, check out the Create a batch transcription guide.
Azure OpenAI Service also supports OpenAI's Whisper model for speech to text with a synchronous REST API. To learn more, check out the quickstart.
Check out What is the Whisper model? to learn more about when to use Azure AI Speech vs. Azure OpenAI Service.
I hope this helps!
