Since the cohort size of the participant is small, we conducted two trials for two participants each and three trials for one participant. Thus, in total seven trials were conducted. A single trial contains four questions. For each question, we recorded the time taken to listen to the question (listening time), answer the question (answer time), the completion time of each question, the number of time the user use cyclic options to listen to the answer option (cyclic), number of time repeat is used for listening question (repeat) and the score for the question which was internally evaluated. Thus, 28 observations (7*4) were recorded.
