Sorry that my reply hasn't helped.
We all have different ways of working, and I am no expert.
(We are all Apple users, like yourself, doing what we can to help each other troubleshoot.)
As I am unable to know which settings are in operation on your iPhone,
it is difficult to know for sure which settings may need changing, or what will be acceptable to you (eg Siri announcements)
Eg: In Settings, you can set up and manage message notifications for the Messages app
No. In this instance you cannot choose the actual words the notification will display..

Other options, if you still need help.
There is a :"Get Support" link to Apple at top right on this discussion page.
or
you might want to take your iPhone into an Apple Store for help / support.
a Genius Bar reservation is recommended:

or
Apple phone numbers around the world

All the best :-)
