UPDATE: This project does not work with Scratch 3. Press the green flag. Please report bugs. Say "spatula bot" to make it listen, too. Clicking on it makes it listen. It's normal to have the green flag be always on. Please give suggestions. Also, use proper punctuation. Say "period" to do a period, say "comma" to make it do a comma, and on and on and on.
