Lernaut & Haupsie went bankrupt in 99 holding the monopoly of every viable dictation platform and the aftermath of a enormous stock fraud that enabled management to hoover up everything at ludicrous valuations eg IBM Via Voice for something like $4BLN cash deal closed in unbelievable time, provided sufficient obfuscation and destruction to lay the sector to rest for two decades.

Microsoft is making a intervention with things purchase the way I see it.

What they have to do is provide a Linux version or at least O365 interop as good with Edge for Linux as Windows.

Nuance support and products are hopeless - my subscription for $120/yr stopped working with ios14 and the app refused to send password reset emails and then we discovered that no online account management existed and cancelled instead of relying on 8/5/300 telephone queuing.
