How do I make a pause in the speech?

Hello everyone
My question is, how can I put a pause of (x amount of time) in before Swift Talker reads the rest of the sentence? It would be like hearing one side of a conversation, someone talking then stops to hear the other persons answer then continues. Any help would great.
And I must say that Callie is a great voice everyone who worked on her gets a pat on the back from me
Thanks for all you're help.
