Re: Colin, you have my empathy & sympathy.
Sadly, Apple are killing Mac.
Every new release they remove an API that programs rely on, insisting that everyone change over to some new API that doesn't do everything the old one could, has a different model and is often buggy as heck.
I'm not surprised that Nuance have stopped trying to keep up.
I would guess that this decision was caused by Apple deprecating the audio subsystem and OpenCL.
It was obvious that many cross-platform applications would be forced to drop macOS support when that happened.
If you have to spend several person-months of developer time just to stay still on that platform, there is a huge commercial pressure to just give up.
