Multi-episodic Perceived Quality of an Audio-on-Demand Service

  • Quality of Experience is traditionally evaluated byusing short stimuli usually representing parts orsingleusageepisodes. This opens the question on how the overall serviceperception involvingmultipleusage episodes can be evaluated—a question of high practical relevance to service operators.Despite initial research on this challenging aspect of multi-episodic perceived quality, the question of the underlying qualityformation processes and its factors are still to be discovered.We present a multi-episodic experiment of an Audio-on-Demand service over a usage period of 6 days with 93 par-ticipants. Our work directly extends prior work investigating theimpact of time between usage episodes. The results show similareffects — also the recency effect is not statistically significant.In addition, we extend prediction of multi-episodic judgments byaccounting for the observed saturation.
