Scenario-Based Design to Envision How GenAI Can Support Sound Design Practices

Sound design involves crafting communicative sonic interfaces such as warning and confirmation signals. An interactive sound design method using musical tension and release with a supporting tool has been explored for practitioners without musical expertise; however, there remain needs for further development of the tool, regarding recommended samples and translated musical knowledge. This paper reports on a project that investigates the use of generative AI applications in sonic interaction design through practitioner-based scenarios. We present two case studies that highlight domain challenges based on a prior study of sound and UX designers, develop two practitioner scenarios from the contexts, and create a prototype of an AI-powered sound design tool with four GenAI applications and four supporting features, tailored to the scenarios. We finally provide reflections on the overall design process and the prototype. This study contributes by extending domain needs into a tangible AI-driven interface through scenario-based design.
