What does the reigning monarch say when dubbing someone a knight, when they touch the person on the shoulders and head with a sword?

Taking Queen Elizabeth II as the "Reigning Monarch" the following site explains investitures in Buckingham Palace. Unfortunately, it does not give us the present day words used by the Queen but I imagine they haven't changed too much over the years.
As magnis2 says...something along the lines of "I dub thee knight; rise Sir XXX"

Those who are to be knighted kneel on an Investiture stool to receive the 'Accolade', which is bestowed by The Queen using the sword which her father, George VI used when, as Duke of York, he was Colonel of the Scots Guards. The Queen then Invests all recipients with the Insignia of their award.

There's this:

In ceremony of knighting, the knight-elect kneels on a knighting-stool in front of The Queen, who then lays the sword blade on the knight's right and then left shoulder. After he has been dubbed, the new knight stands up, and The Queen invests the knight with the insignia of the Order to which he has been appointed. Contrary to popular belief, the words 'Arise, Sir ...' are not used.
