We do Josh with Control 4 and it works great. I'd have no reason to believe it wouldn't work as well with Crestron. The thing about Josh is that it can actually stand independent and provide some automation and control on its own, especially if you're a big user of Lutron and Sonos.
Josh.ai is a home automation focused voice recognition device, that can be connected with home automation platforms such as Crestron Home, traditionally programmed Crestron systems, Control 4, etc. They do not use your voice for any other purpose than controlling your home. I have two Josh micro appliances, but I have not gotten get them setup due to other tasks with my Home OS3 setup taking priority and being swamped with work.
