MERAK AVATAR CONVERSATION DEMO Scripted demonstration with two synthetic voices. Learner replies are written for this example; no microphone or live conversation is involved. All five characters use the same voices and script. You · scripted reply: I finished the gravity path, but orbit still feels strange. Merak: You wrote earlier that objects fall together when air resistance is ignored. What part of orbit is hard to picture? You · scripted reply: I can picture falling. I can't picture falling without hitting Earth. Merak: Then let's focus on how falling and sideways motion fit together. You · scripted reply: Yes. I don't want to start the whole path again. Merak: We can use a sketch, or talk through one example. What would help? You · scripted reply: A sketch first. Then I can tell you what still doesn't fit. Merak: Let's start there.
