Hello @Taine Morrish ,
Thanks for posting your question in Microsoft Q&A.
The Azure AI Fast Transcription API is engineered to deliver efficient and scalable transcription services while prioritizing the confidentiality and security of audio data and transcriptions. Although the documentation for Fast Transcription may not be as comprehensive as that for Real-Time and Batch Transcription, we can draw important insights from Azure's overarching security practices and the information available for these other services.
In summary, while explicit documentation regarding the confidentiality measures of the Fast Transcription API may be limited, it is reasonable to assume that it adheres to the same robust security principles as Azure's other transcription offerings. For the most accurate and up-to-date information, we recommend wait for the latest resources and documentation.
I hope this is helpful!
