Hello Alice Candido Martins,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you are having error creating Speech Service resource with Azure for Students subscription (RequestDisallowedByAzure).
To successfully deploy the Speech Service in Azure under your Azure for Students subscription, begin by identifying your allowed regions. Sign in to the Azure Portal and navigate to Subscriptions. Select your student subscription, then go to Policies under Settings. The “Best available regions” listed here are the only regions where you’re permitted to deploy resources. This list is dynamic and reflects your current subscription configuration. For general guidance, refer to the Azure for Students FAQ.
Next, cross-check which of your allowed regions support Cognitive Services, specifically the Speech Service. Use the Azure Products by Region tool. Filter by “Cognitive Services” and input your allowed regions to find compatible deployment zones. Only regions that appear in both lists are valid for your Speech Service deployment.
When creating the resource, choose the Free (F0) pricing tier. If this tier is unavailable (greyed out), it means the region has exhausted its free-tier capacity. This is a known limitation because Microsoft restricts F0 tier availability per region. You can review the Speech Service quotas and limits for more details. In such cases, try other regions like Central US or West US 2, which typically have higher capacity.
If all valid regions fail to support the F0 tier, you should raise a support ticket. Visit the Azure Support page, select Technical as the issue type, and choose Cognitive Services > Speech Services. Include a clear description of your issue, referencing the regions you've tried, and the error message received.
I hope this is helpful! Do not hesitate to let me know if you have any other questions or clarifications.
