Unpacking Practitioners' Attitudes Towards Codifications of Design Knowledge for Voice User Interfaces

Recent HCI research has sought to develop guidelines-'heuristics', 'best practices', 'principles' and so on-for voice user interfaces (VUI) to aid both practitioners and researchers in improving the quality of VUI-based design. However, limited research is available on how such design knowledge is conceptualised and used by industry practitioners. We present a small interview-based study conducted with 9 experienced VUI industry practitioners. Their concerns range from terminological challenges associated with VUI design knowledge, the role of codifications of such knowledge like design guidelines alongside their practical design work, through to their views on the value of 'harmonisation' of VUI design knowledge. Given the complex-albeit preliminary-picture that emerges, we argue for HCI's deeper consideration of how design knowledge meshes with the contingencies of practice, so that VUI design knowledge-such as design guidelines developed in HCI-delivers the most potential value for industry practice.
