Your s/// for converting characters to lowercase is far too much work, and the use of $& is poisonous. I'd use the lc() function.

And you're using substr() where chop() would do, and probably where you could just use split(). 

while (<STDIN>) {
  $count{$_}++ for split //, lc;
}

Is how I would optimize your input loop.
