WHY?
Rhetorical questions lead to an
interaction failure
A rhetorical question is a question that is asked to make a
point rather than to elicit an answer. Though a rhetorical
question does not require a direct answer, in many cases
users answered and the interaction failed because Pepper
was (and still is) not able to manage many answers.
The rule is simple: A question must always:
• Finish with a question mark.
• Be at the end of a spoken phrase.
• Expect an answer.
EXAMPLE
Don't: “Wasn't that funny? I have another joke.” because the
user could answer the question, but Pepper doesn't expect
an answer.
Do: "That was so funny. I have another joke."
