Training custom model in Speech Studio results in "Internal error."
I'm trying to train a custom Speech-to-Text model in Azure AI Speech Studio for Danish speech.
I have made a structured text phonetic pronunciation markdown file.
The markdown file uploads without errors as a speech dataset. However, when I try to train a custom model using this file the status says "Processing" for a few days and then fails with the enigmatic "Internal error." message.
I have tried to simplify the markdown file, reducing it to only a few simple words to see if that would help, but the custom model training still fails with the same error message.
I have created a similar file for English speech and successfully trained a custom model.
I am at a loss for what to do now as the error message doesn't help with the troubleshooting and every step up until the training seems to be correct. Has anyone experienced similar problems? Am I missing something?
