eChipmunks

Who actually voices the Chipmunks in Alvin and the Chipmunks new album Undeniable?

I was told it was Ross Bagdasarian Jr and Janice Karman but when slowed down it doesn't sound like them. it actually sounds like Jesse McCartney and two other male singers. If anyone could help that'd be great.X
