Olly defends Simon Cowell
Last year's X Factor runner up Olly Murs has defended the X Factor by saying that when he was on the talent contest no auto-tuning was used.
The singer watched his audition over an over and did not detect any voice tweaking .
The X Factor has been criticised regarding claims that auto-tuning has been used on the show to make hopefuls sound better than they actually do.
