What are all the dictation commands in iOS? (iOS 10)
One command that isn't on the list yet:

• "quote" will give you a space then "
• "end quote" will give you a " then space

In other words, say quote at the beginning of a quote and the following text will follow the "like this with no space, and saying end quote will put the quote marks right after the word like this" with no space before the quote. Saying quote again at the end will put a space before it like "this and put it in the wrong spot.
