Speaking

As long as you can act, you can also speak. You don't need to spend any type of action to speak, but because a round represents 6 seconds of time, you can usually speak at most a single sentence or so per round. Special uses of speech, such as attempting a Deception skill check to Lie, require spending actions and follow their own rules. All speech has the auditory trait. If you communicate in some way other than speech, other rules might apply. For instance, using sign language is visual instead of auditory.
