As far as words go, you could just sit by yourself and think to her "ping" and ask her to respond with "pong." If you think you made up a "pong" yourself, switch roles- you wait to respond until she pings you, giving her control and helping you improve your attention for her responses. If you think you made up another one, switch again. Repeat until you've consumed a significant portion of your day.
Best case scenario, you start to hear her voice better and then she gets to yell at you for not giving her enough tupper sex. Tuppers seem to like yelling occasionally.
