I got the following error from the speech to text REST API version 3.1:

{"code":"LimitExceeded","message":"The audio length exceeds the limit for diarization. Please shorten the audio."}

I had the language set to "en-GB" and diarization set to "minCount":2,"maxCount":9. The length of the recording was 15325 seconds. Does anyone know what the limit is? I couldn't find it in the docs. Would be great to get that information to handle this better in my application.

    Matej Svejda If you are using batch transcription API with diarization enabled then the limitation of file length is 240 minutes. Please see this page from batch transcription API configuration properties. Try shortening its length to just below 240 and check if it goes through. Thanks!!

    Hi,

    the quotas and limits depend on your pricing plan, you can check it from here: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/speech-services-quotas-and-limits

    hope this helps
