Thanks for reaching out to us again and thanks for your response, it's possible to increase the quota of whisper model for paid subscription, but currently we need to do it by email, in the near future there will be a process posted in the document.
If you need it now, please send me an email to Azcommunity@microsoft.com with title ATTN:Yutong also with below content, I will forward your request to product team for review -
the name of the customer, what your scenario is, what industry you are in, your subscription ID, resource ID, region, and the requested quota increase.
Product team will review your case.
I hope this helps.
Regards,
Yutong
