The singer admitted that she doesn't like to see music turned into a competition.
"I was approached for The Voice in Britain but I don't think so," Stone told the Daily Express.
"The thing is I love music and I love singing with other people and I don't see it as a competition at all. I feel that those things are really good to get exposure but they kind of make it into a competition and that is just sad.
"Other than that it is great because they get to be heard by millions and they never would have been before."
Stone got her big break after winning BBC talent show Star For A Night back in 2001.
She will play a show at Shepherd's Bush Empire on September 5 in support of her new album The Soul Sessions Volume 2, which recently entered the UK album chart at number six.
Jessie J and Sir Tom Jones are rumoured to have quit The Voice UK after just one series.
