Speaker Recognition API still returning “Unauthorized – gated service” although Speech token works. Limited access form not available in my Azure portal.

Hello,

I am trying to enable the Text-Independent Speaker Verification API in the Central India region. I already created a Speech resource and verified that the subscription key is valid. When I request a Speech token using:

POST https://centralindia.api.cognitive.microsoft.com/sts/v1.0/issueToken

I receive HTTP 200 OK and a valid JWT token. Here is the full successful response for reference (truncated):

HTTP/2 200
content-type: application/jwt
x-ms-region: Central India
eyJhbGciOiJFUzI1NiIsImtpZCI6ImtleTEiLCJ0eXAiOiJKV1QifQ...

This confirms that the Speech Service is active and my subscription key is valid.

However, whenever I call the Speaker Recognition API to create a verification profile, I still receive:

"Unauthorized – This is a gated service, make sure your Azure Subscription ID is approved."

Previously I was told to submit the approval form at https://aka.ms/azure-speaker-recognition, but this link now redirects to documentation instead of the actual request form.

In addition, when I search in Azure Portal for “Limited access features”, I do not see the Azure AI Services Limited Access option at all. Only unrelated results such as “Feature previews” and “Disk accesses” appear. I have verified the following:

My account is part of an organization tenant (Web4Next Technologies).

My subscription type is Azure Plan (Pay-As-You-Go).

My role is Owner on the subscription.

Region is Central India.

Standard Speech API works correctly using the same key.

Despite this, I am unable to find any way to request access for the gated Speaker Recognition API. I had raised a similar question earlier, and followed the guidance provided, but the issue still persists. It seems that Microsoft may have changed the approval flow, and the required form or UI is no longer available in my portal.

Could you please help guide me on the correct process to request access with the current Azure flow? Any updated documentation or steps would be very helpful.

Thank you.
