Mocking the BBC singing contest's recent loss of popularity, the Live at the Apollo comic said that "people aren't interested" in this year's competition.
Speaking on tonight's (June 1) Alan Carr: Chatty Man, he said: "I had a load of jokes about The Voice when it started. I was quite excited about those jokes, but nobody cares about them now.
"I say to my audiences, 'Are you watching The Voice?' They are like, 'No'. They don't laugh at the jokes.
"My Voice jokes were about the beginning when they had the twisting chairs - that was fun. They had their backs to them and if they liked them they would press their button and turn round.
"Once in a while you could sense that the person was so unattractive they were never going to have a career, which is why I thought there should be an emergency button so they can turn back round.
"But that joke stopped working because people aren't interested."
Carr also poked fun at The Voice's fall from grace, jesting: "This weekend is the series final and if they want to get those viewers back, they'll have to think outside the box and persuade Holly Willoughby's breasts to sing a duet. Now that would be worth tuning in for.
The Voice has even been beaten by Planet Earth Live. So perhaps for series two the BBC should combine the two and just film badgers having sex in revolving chairs. I'd watch. I've heard of singers miming to protect their voices but not their whole bloody career, for God's sake."
The 2012 Voice UK final airs on Saturday at 7.20pm on BBC One.
