Hi Charles,
Dictate Feature will stop after few seconds if you didn’t speak or you don’t have any reaction. It’s not an issue, this is how it designed.
We are sorry for the inconvenience caused by this, you can kindly submit feedback in Office application. It’s the direct way to report this advice to related team. For your reference: How do I give feedback on Microsoft Office?
Thanks for your cooperation.
Regards,
Ivy
