The construct of recommendation complexity has been created, which is the degree of detail and amount of information recommendations are presented. Differences in this domain of computer-human-interaction are explained by media richness theory, an application of neuro-ergonomics. Data was collected through a survey conducted on the crowdsourcing platform Amazon MTurk. The sample consisted of 178 US consumers that had purchased goods using both e-commerce and voice commerce. Structural equation modeling (SEM) was used as well as multiple regression analysis for statistical hypotheses testing.

This research enables product managers to recognize which factors of customers satisfaction differ from those in e-commerce. While developing their voice commerce strategy and system design, managers should emphasize convenience factors such as ease of use and ease of understanding, as we
