Not sure how this plays out if you have not deleted the game before the DLC came out. I did delete my game, so I had to start again.
After reinstalling the game ..... and starting over...
The achievement popped after using the microphone on my 10th picture. It doesn't have to be in a row. I had used the tap screen method twice during the first 12 cards.
The microphone is on the top half of the playing screen. It's the icon on the bottom left side of the picture. Sets underneath the icon with two heads. It's obvious which icon as the other side(right) has the eye & basket.
I've noticed on 3 different phones now this is very touchy. Tap the icon, and follow with your voice answer. Now, as MCASguru stated ... sometimes you have to say it slightly off to make it register correctly. dale smeegle & others with his issue ... I've had a few of these that simply wouldn't accept my voice answer, but most will work. A good point was made by MadMirror in that you sould make sure the language setting are correct ... also in setting you can find the Cortana tab which gives you the instructions on how to use the voice/microphone answer.
So, if you have noticed or just read the comments below .... this game is now super buggy after the title update. Sometimes this achievement is glitching, and even the 5 day achievement is glitching out or more than 5 days are required. I know some are having the game load only to have it quit every time. Others are popping achievements but they don't register on xbl .... These are all common issues with the free games. Not much to say about a game that's buggy making the simple achievements not work right or not at all. Most are uninstalling & reinstalling for a fix, however this is not working for others.
