In a question-driven phone assistance system, if the answer to one question decides the next one, hiding user's answers is not enough to protect her privacy. In this work, we explore an audio streaming mechanism where the assistance system is not aware of the questions that the user retrieves. In addition, we discuss the deployment of these mechanisms on a real system, using VoIP schemes and cloud computing.
