Voice recognition for naming icon groups?

[Sevendipity]

So grouping app icons is easy; works the same as on the iPad (tap and hold, then drag to another icon or a group). When I open the group, it's named Unnamed Folder. I tap the name and it gives me the keyboard for renaming it. I try to use voice recognition, and it gives me choices for what it thinks I said. I tap the correct one, and ... nothing! I have to use the keyboard to rename the folder.

What am I missing here?
