Caulker will join Swans for the new season after penning a contract extension this week with Spurs.
He told the Spurs website: "It's all very exciting for everyone involved there. I played against them last year and you could see they're a good footballing side, so I'm looking forward to playing there. They play in the style I'm used to at Spurs, and although it's going to be new, it's going to be enjoyable.
"I honestly think they'll do well. I said it last year when we were looking at who was going to go up and I said if Swansea do go up, they'd have a good chance of staying up. Fingers crossed they will and I can be part of it.
"For me the main thing this year is getting games and, with that, the performances as well, so it's a great challenge. My family and I are more than excited - it's going to be a massive year but one in which I'm ready to take on the challenge."
