When using "voice typing", how can I capitalize a proper noun?
Picked up from this Ruben Roy answer in a more recent question:

You can use this comments to start and stop typing with capitals with the Google voice typing Android keyboard.

"Caps &lt;word&gt;"                           Type with an initial capital
"All Caps &lt;word&gt;"                       Type in all uppercase
"Caps On"                               Start typing words with initial capitals
"Caps Off"                              Stop typing words with initial capitals
