Kanye West has been criticised by fellow rapper T-Pain, for not using auto-tune "correctly".
As a fan of the software, T-Pain helped popularise its use and thinks that though Kanye makes "great" music, he isn't using the voice processor to the best of its ability.
Speaking to HuffPost Live, he explained: "Kanye uses it, but he doesn't use it correctly. He makes great music with it, but the way that I use it and the way that I've shown Chris [Brown] and Jamie [Foxx] to use it, he doesn't use it that way."
The singer stated that Kanye should use auto-tune to "catch mistakes" before they happen.
"[Kanye] sings without it first and then he puts [Auto-Tune] on after he's done with the vocals.
"You don't know how it's going to come out. You can't catch your mistakes before they happen. So sometimes it gets a little bit wobbly and things like that..."
"[808s & Heartbreak] was actually good, but I had a lot to do with that album." he added.
