Certain iOS dictation commands stopped working

There’s a thread at Apple’s Discussion Boards pointing out that certain iOS dictation commands are behaving differently than they did a few months ago. Specifically, users note that saying “Caps on” and “All caps” used to toggle caps lock on and off. Now, the iPhone and iPad (3) simply type out the words “caps on” and “all caps.” Several users state that turning Siri on and off fixed the problem when it occurred before, but not anymore.

Another user reports that saying “numeral three” used to result in “3.” Now, his iPhone types out the words “numeral three.”
