More recently Google, Microsoft, Apple, etc. decided they wanted to have speech recognition as an internal piece of their platforms.
Google poached lots of Nuance's talent. And then Microsoft bought what remained of the company.
Now speech recognition is a service integrated into the larger tech company's platforms, and also uses their more statistical/ML approaches, rather than being a component created by specialist companies/groups.
(I'm sure I'm grossly simplifying this — just seeing a potential parallel.)
