It seems that you are experiencing issues with accessing the Custom Neural Voice feature in Speech Studio despite receiving approval. Here are some insights that may help address your questions:
- Resource Access: Custom Neural Voice approval does not automatically apply to all resources in the subscription. Each resource may need to be manually enabled for Custom Neural Voice access. Ensure that the specific Speech resource you are using has been enabled for this feature.
- Roles Required: The role of "Cognitive Services Speech Contributor" is indeed necessary for data plane access to Speech services. While Owner and Contributor roles provide broad access, they may not grant the specific permissions needed for certain functionalities in Speech services. It is advisable to assign the appropriate role to ensure you have the necessary permissions.
- Activation Steps: After receiving the approval email, there may be additional steps required to activate the access. This could include ensuring that the resource is correctly configured or that any necessary settings are applied.
Given that you have already tried creating a new Speech resource and waited for permission propagation, I recommend checking the specific configurations of your Speech resource and ensuring that the correct roles are assigned. If the issue persists, contacting Microsoft support for further assistance may be beneficial.
