Human-robot interaction studies in the Caribbean currently face two challenges. First, the robots used in these studies have difficulty understanding many of the regional accents spoken study participants. Secondly, the global pandemic has made in-person HRI studies in the Caribbean more challenging due to the physical and social distancing mandates. This paper reports on our exploratory study to determine what kind of impact these two challenges have on HRI by evaluating the effect conversational repetition has on a human-robot conversation done using video conferencing software. Using network analysis, the results obtained suggest that conversational repetition has several subtle relationships on perceived workload. One interesting finding is that frustration and effort are indirectly affected by conversational repetition. Results from the short User Experience Questionnaire indicate that the overall quality of the user experience is perceived as positive-neutral. This encouraging result indicates that video conferencing may be a suitable interaction modality for HRI studies in the Caribbean.
