Thank you for fixing the tab/space indentation problems, it’s working now.
I’ve tested the new try/except mechanism:
-
invalid configuration options for google: works, the error “An error was encountered when transcribing: 400 Invalid recognition ‘config’: The phone_call model is currently not supported for language : de-DE.” was correctly embedded in the voicemail as text.
-
google server not responding (to simulate this, I added 8.8.8.8 accounts.google.com oauth2.googleapis.com www.googleapis.com to the /etc/hosts file) => took a long time, but error was properly embedded in the voicemail message and the message was correctly delivered: “An error was encountered when transcribing: Deadline of 5000.0s exceeded while calling functools.partial(<function _wrap_stream_errors..error_remapped_callable”
So far, so good, however:
- invalid json file specified in configuration: doesn’t work, voicemail is lost. When manually processing the voicemail, sttparse crashes this way:

So it currently correctly catches the specific reason of a google server responding with an error and the google server not responding at all, but not an incorrect json configuration file, incorrect json authdata in the file… If you have time for further reliability improvements, this would be much appreciated. Perhaps there could some very generic error handling, so whatever the error was, at least the voicemail continues to be delivered? I don’t know if in python you can catch those generic Traceback messages and just embed them as transcribed text - that’s how I would approach it in C#.
