Will.i.am confesses that he uses 'autotune' computer programming on his vocals.
The Black Eyed Peas bandmember and music producer is currently a judge on UK talent show The Voice.
Will.i.am has an illustrious career as a composer of songs, but the musician admits that he is not the best singer.
'I use autotune because I write and produce,' he told British newspaper The Mirror. 'A lot of the time I am in the studio by myself and no one works as much as I do. So the computer allows me to make music singing myself and not wait around for singers to come and sing it. It's a rare combination to have someone who can write songs and sing well.'
Will.i.am appreciates the range that technology provides him.
'The computer allows me to execute my ideas at the speed I think them,' he explained. 'So that's why I lean to autotune. It's just an effect. But I am working on, you know, my singing abilities.'
