An example of the flow I mean, where my skill's invocation name is Example Quiz, and there's a slot type 'vehicle' with values 'car', 'ship', 'submarine' or 'helicopter.'
USER: "Alexa, start Example Quiz."
ALEXA: "Welcome to Example Quiz. Before we begin, what vehicle are you in? Car, ship, submarine, or helicopter?"
ALEXA: "A submarine, excellent. Alright, question 1. Alfred Hitchcock was famous for what? A, writing novels. B, directing movies. Or C, breeding horses."
ALEXA: "Correct! Question 2..."
I'm confused about how I'd capture the submarine response, and what intents I would need. My instinct was to handle the initial launch request by saying "Welcome and what vehicle", then listening, and to have a SetVehicleIntent with a single-word slot utterance -- but that fails with "bad request" when I try to build the interaction model.
What's the correct flow for a situation like this?
