Audio transcription: does it work if the files are registered on PC ?

[laurencedec]

I register my webinars on the cloud and I don't have any pronblems with the audio transcriptions.
I have a fiend who would like to make audio transcriptions from this webinars that last 90 minutes which he downloads on his hard disk. But he doesn't find the audio transcriptions file?
I don't know how to help him so far. I wonder if there is a duration limit on the transcription or if the problem comes from the fact that he registers his files on the hard disk? I thought he might shut down his PC before the transcription was made but he says it is not the case.
Any idea or feedback welcome.
Thanks in advance
