"Who's Speaking"

Dialogue is a total loss unless you know who's speaking. In a long dialogue with no attributives your reader will be lost or confused. They will have to back track and re-read to figure out who's been talking. Place your attributives where they would come naturally, or where the reader would take a breath. Read your long dialogue out loud. This will usually find where you need a 'said'

Happy writing,
