Just a warning for anyone interested. I go to a writer’s group and read a lot of writing books by professionals, and I’d advise against the “said is dead” pic. Most pros frown on replacing said with most words other than asked.
The ‘said’ tag is supposed to be invisible to the reader. Instead of replacing the tag, try and put an action or feeling instead. Better yet, make sure your character’s dialogue is so distinct from one another, that you don’t often need tags.
