Issues with Processing Encrypted WAV Files Using Fast Transcription API

Question

I have successfully used the Whisper model to transcribe a batch of 50 encrypted WAV files without manually inputting the file paths. However, I'm encountering difficulties when attempting to perform the same task with the Fast Transcription API. Could you please explain why the Fast Transcription API is unable to process these encrypted WAV files? Additionally, what steps can I take to ensure that the Fast Transcription API can transcribe all the encrypted WAV files in my folder?

Hi Farnaz Zinnah

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

I understand that you are encountering an issue, The Fast Transcription API is designed to work with audio files that are directly accessible and not encrypted. Encrypted WAV files cannot be processed because the API requires the audio data to be in a readable format without any additional decryption steps. To ensure that the Fast Transcription API can transcribe your WAV files, you will need to decrypt them first, make sure that they are in a supported format and accessible via a public URI or through Azure Blob storage without encryption. Once the files are decrypted and accessible, you can use the Fast Transcription API to transcribe them.

Thank You.
