Am attempting to delete a Cognitive Service Custom Speech Model. However the following error comes up
The model is referenced by a transcription. Please delete all transcriptions conducted with this model first.
I have had this issue on a model from a year ago but disregarded it since it wasn't causing an issue but now it has appeared on a brand new model trained yesterday that I am trying to delete.
I have no idea what on earth the "transcription" being referred to is, nor how I ended up having one or how to delete it. Nothing has been done with this model that hasn't been done with others that have been successfully deleted.
All tests using the model have been deleted.
In the end I used the https://westus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0 APIs to delete the transcriptions.
