Had an Xbox One for approx a year now, all working well until recently, it stopped responding to voice commands. 
It just point blank ignores everyone. Camera appears to be working fine as it recognizes me when I walk into the lounge and logs me in.

Been through all the settings to ensure its set to correct region etc but still nothing.....

Only thing I can try is a factory reset of the Xbox - annoying but not left with much else to try :)

Anyone else had this issue ?

Also, anyone know if I do go ahead with a reset, what happens to my save games etc - are they stored in the cloud, or locally on the HDD ? (Havent looked into it)

TIA
