The legendary voiceover artist said he could see the appeal of the Essex-born singer to X Factor viewers, who he described as "the broadest audience you can imagine".
When Digital Spy asked for his thoughts on Clark, Dickson replied: "[The X Factor is] a big, fun, friendly family entertainment show.
"As such the cast, or contestants, on the show have to reflect the audience... they watch the show together, it's a real family, fun experience."
Dickson also insisted that he doesn't mind people constantly asking him to announce their voice X Factor-style.
"It's part and parcel of the job isn't it, it goes with the territory," he said. "Everybody wants to have their name shouted out like I do on the telly.
"I get queues when I go to parties, or even at The X Factor the contestants come up to me and thrust their mobile phone in my face. It's only natural, I'm quite happy to do it."

However, Dickson admitted that this year's X Factor was not a "vintage year for names".
Reflecting on memorable X Factor monikers, he continued: "Of course who could forget Rachel Adedeji?
"And I was gutted when Gamu Nhengu was booted off at the early stages of the competition. I was looking forward to saying her name".
Dickson was available thanks to X Factor live final partners Pepsi Max and Walkers Extra Crunchy, who are giving consumers the chance to win tickets every hour to the show's live final weekend on December 8 and 9 through an on-pack promotion. More information is available at pepsi.co.uk.
