I have just updated to 10122 and am now having sporadic issues with Cortana. (I'm typing in Edge and autocorrect does NOT like "Cortana"). I am experiencing intermittent issues with no voice. Sometimes when I give a command I get an audio and visual response. Sometimes no audio. This is to the same statement such as tell me a joke or the weather. Sometimes she speaks, other times she doesn't. I did not have the issue with the previous build. Surface Pro 3 i7 256. I also notice in Edge the favorites bar becomes unstable when not in max screen.
