Hi Ben Aziza Rayen,
Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!
It looks like you're encountering a DenyAssignmentAuthorizationFailed error when trying to create an instance of Azure Speech Service using your student subscription.
To resolve this issue, you need to check if there is any deny assignment in place that is blocking your access.
If you are not sure how to check the access policies, you can follow these steps:
- Go to the Azure portal and navigate to the subscription or resource group where you are trying to create the Speech Service.
- Click on the "Access control (IAM)" tab.
- Check if there are any deny assignments listed under the "Deny assignments" tab.
- If there is a deny assignment that is blocking your access, you can either remove the deny assignment or modify it to allow the action you are trying to perform.
Hope this helps. Do let us know if you have any further queries.
