Gobo pretty much explains it all. :D Credit to me. :D I got the idea from a game called Swordigo a while ago. I also saw a game on the front page that had it too, which inspired me to make my own. Here's a "game" that this script is used in: http://scratch.mit.edu/projects/39153318/
Here are all of the blocks currently used in this project: •The "Say ()" purple block says whatever you put there forever, after typing it out. •The "Delete what I said" block deletes whatever your sprite is saying. •The "Say () for () seconds" block types out the text, then waits the amount specified before deleting itself. •The "Say () for automatic amount of seconds" block automatically calculates how long the sprite needs to say your text based on its character amount.
