Thought I would provide further update which is on a negative as I have had to stop voice recognition as it failed more times than it worked.

I was not able to isolate why as the failure was not constant so I was unable to go "Ah that's it" my only suggestion is that maybe one of the programmes CC/MS speech is going to sleep and losing the connection . MS does seem a little flakey as currently I stopped MS voice recognition and it wont start again unless I reboot

Sorry I couldn't be more help

I was trying to use it in always on mode, Bluetooth headset, xbox with pc app
