You wouldn't need any kind of special training for this. Just the ability to do simple things like make calendar appointments, draft emails/responses, and set reminders based on time/locations/etc. It really doesn't seem very complicated but as far as I know no one has figured out how to do it yet. All the existing "assistants" are so bad that I don't even bother trying to use them anymore. They can't even do something simple like turning on a light with any degree of reliability.
