Abstract: The average attention span of humans is decreasing. To adapt to the change, researchers investigate visual and auditory techniques that alter the perception of time passing. However, the auditory technique is underexplored in comparison to visual techniques, which are becoming increasingly important as voice assistants, speech interfaces or time-aware computational/robotic systems proliferate. This paper investigated the effect of pitch and interval variables on time perception. Three pitch levels (static, falling, rising) and two interval patterns (static, narrowing) for a total of six auditory stimuli were compared. Principal findings indicated that rising/falling pitch and interval narrowing, as well as their combinations, can be used to shorten the perception of time. This research contributes to a better understanding of end-users' subjective temporal estimation of auditory stimuli, which can be used to further develop audio-based interactive devices/agents.
