People with lisp now lisp on radio (#3760)

# About the pull request

The lisp trait did not affect a flag for speech, making it so lisping
does not occur over radio, this should make it so what they say is
transmitted properly.

# Explain why it's good for the game

Fixes an oversight and allows for lisp speech to be handled by the
handle_speech_problems method. Also realism or something
