You're messing up your grep().  (And you don't have warnings on, or else
you'd be given some warnings that might help you figure things out.)

grep() comes in two flavors:

  grep { CODE } LIST

and

  grep EXPR, LIST

The first form has no comma, the second does.  Your code is the 2nd form,
and you're logically negating a hash reference.  You want either

  grep { !/^$spkr/ } @list;

or

  grep !/^$spkr/, @list;
