	This looks quite inefficient, tr will do the case conversion
much more efficiently than dd, and it can also split the file into one
word lines. So try:

tr 'A-Z\011 ' 'a-z\012' < filename | sort -u | wc -l

or

deroff -w filename | tr 'A-Z' 'a-z' | sort -u | wc -l

depending on whether you wish to remove nroff macros or not.
