Hidden Talent is a feel-good series taking ordinary members of the public and testing them to find out if they have an extraordinary talent that they didn't even know about.
Digital Spy caught up with Richard to talk about the show, reality TV and why he'll never do Strictly Come Dancing.
As an interviewer, do you enjoy being interviewed yourself?
"I don't actually enjoy it. When you're used to interviewing someone then you like being in control of the interview. There's something slightly unnerving about being interviewed, it's interesting to see why some guests can get on edge.
"As the interviewer on radio, I get through so many, and I don't understand why a guest would be defensive or nervous about it. But I guess this helps me realise why."
What is Hidden Talent?
"It's basically a science show. We've run tests on many hundreds of people to find out if they've got a hidden talent that they didn't know about. You know that TV show Faking It? I think of it as Not Faking It.
"We put adverts out in local papers and we had what you call catch days, like the audition days on other shows and hundreds of people came along and they didn't know what they were being tested for."
How is it different from other TV talent shows?
"If you go to an audition for Britain's Got Talent or The X Factor, you know that you're going because you like the idea that you could be a singer.
"With our project you don't know actually what you want to do and you don't know what you could do. It's not about people who think they're good at something, it's about people thinking maybe they could be good at something, they're just not sure.
"One example is a kid who was 19, living in a homeless shelter, who came along to one of our test days and we ran this exam on him that they use in the British army and we found out that he'd got just this incredible ability to learn languages.
"So we taught him Arabic and he learnt to speak Arabic fluently in 19 weeks. He could write it after 19 weeks as well. This kid had only been abroad once to Spain. He's never learnt another language and had no interest in learning another language.
"When you go to language school it will often take you a couple years, maybe three years, to speak Arabic fluently because the language has nothing in common with English. So he goes with nothing to Arabic and for the big finale we took him to Jordan and we put him on Jordan's own This Morning, where he spoke for 20 minutes and spoke fluent Arabic. It quite an incredible story."
Has reality TV made people desperate to have talent and have something special about them?
"I think those shows have probably made a lot of people dream of fame, they seem like a shortcut to fame and I think those shows appeal to those who want to be famous.
"I'm not sure our show did that and you'll see when you see the programme, we're not really dealing with extroverts or eccentrics. I don't think we have attracted those sort of people, we are dealing with people who want to find out an ability of some sense.
"I don't think any of them imagined when they came it was going to be about being famous and it's not. It's not the same sort of thing. I think those sorts of programmes, in the broader sense, they are all about people dreaming and about doing something different, something else, something better and probably more exciting."
Have you never been tempted to take part in a reality show?
"I don't want to go on these shows for a desperate career move and I'm not short of work. Even if I was, I wouldn't like myself for going on it. That one show where people learn in front of an orchestra (Maestro), those sorts of ones, I'd probably consider one where you can learn a proper skill.
"Having said that, I won't do Strictly Come Dancing. I would go out first on Strictly Come Dancing."
As someone who has worked in front of and behind the camera on TV shows, where do you stand on Simon Cowell? TV hero or TV villain?
"He's not a villain. A lot of people would like to be in his position. He can really call the shots over a broadcaster. Normally when you're making a show then the relationship with the broadcaster is one in which they are the boss. He seems to flip that round with the broadcaster both here and in America. He's the boss and that's the relationship they have with him.
"And to have that much leverage, influence and power over major broadcasters in Britain and America is an astonishing thing to achieve, almost no-one else has done that."
What would you have done if you hadn't made it as a TV presenter?
"At one time I wanted to be an MP, quite whether I would have made it as an MP is another thing. I was really obsessed by politics. I still am.
"I always liked the idea of radio and politics, so if I hadn't made it in radio then it's politics. I'm quite glad that I didn't, though, because it's generally large and unrewarding work. I don't really want to be taking constituency meetings talking to locals about their burst pipes, which is the reality of a lot of MPs' work."
Hidden Talent starts tonight (April 24) at 9pm on Channel 4.
