Model the session before building its interface
Begin with the approved script and the decisions that move a person through it. Name each step's expected input and the response that follows. A session may ask a question, play a prompt, wait for repetition or return to an earlier step. Decide what happens when a response is unclear or the participant wants to stop. Keeping the method explicit gives the content owner and engineers a common way to review the experience before adding voice recognition and visual controls.
