Other studies that have found seemingly distinct authorial voices within the Book of Mormon include:

Grant Hardy.  Understanding the Book of Mormon: A Reader’s Guide (New York: Oxford University Press, 2010)

Roger R. Keller.  Book of Mormon Authors: Their Words and Messages (Salt Lake City: BYU Religious Studies Center and Deseret Book, 1996)

And, of course, the classic computerized statistical wordprint studies introduced here:

You have to hand it to Joseph Smith, being able to create such varied voices while rapidly dictating his frontier religious yarn on the fly . . .
