EXPRESS: Brand and Product Presentation in Voice Shopping: Investigating the Effects of Message-Design Adaptations

Voice shopping is on the rise. However, with the absence of visual stimuli, consumers face difficulties in processing brand and product information during the shopping process. Drawing on load theory of attention and the literature on imagery and information processing, we conducted two studies to examine how the level of imagery in auditory product descriptions and the number of product attributes shape consumer responses. Our results indicate that high imagery descriptions increase brand stimulation, which in turn improves brand attitude, purchase intention, and actual product purchase. Additionally, the imagery level of an auditory product description positively influences brand recall directly. These results provide new insights into how auditory message design shapes consumer evaluation and decision-making in voice-based shopping contexts.
