I have to extract text from audio files (which are extracted from a video). Does this support mp3? The audio files can be longer duration, should I use SDK or Rest API?.
@Kidd_Ip in my case the audio are extracted from a video & have to be processed in the background (as of now when the app is running) without playing it & without user interaction. The audio can be more than a minute & doc says speech SDK can recognise from file also. My confusion is the speech SDK doc says there is method for continuous recognition till stop continuous recognition async is called so this method should be used only for microphone as in an existing file which is to be processed without user interaction we won't know when to call stop? Or the rest API for batch transcription is suitable for my requirements?
