Speech Studio - Error in exporting data from editor to dataset section

Hello Shree !

Thank you for posting on Microsoft Learn.

I checked similar issues shared in the community common causes :

• service-side regression (bug introduced in recent updates)
• storage permission change (editor and dataset modules rely on internal storage, if RBAC or storage account access changed, export might fail)
• corrupted or malformed transcripts (even in previously working datasets some validation rules might have changed)
• region-specific issue (specific Azure region Speech Studio backend having issues)

Try using REST API directly to upload data into a training dataset instead of relying on the Studio UI https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-speech-to-text#create-dataset

or if possible, create a test project in a different region to check if it’s region-specific.

If this persists (and especially since it worked before), this likely requires support intervention.
