Current sound recognition systems for deaf and hard of hearing (DHH) people identify sound sources or discrete events. However, these systems do not distinguish similar sounding events (e.g., a patient monitor beep vs. a microwave beep). In this paper, we introduce HACS, a novel futuristic approach to designing human-AI sound awareness systems. HACS assigns AI models to identify sounds based on their characteristics (e.g., a beep) and prompts DHH users to use this information and their contextual knowledge (e.g., “I am in a kitchen”) to recognize sound events (e.g., a microwave). As a first step for implementing HACS, we articulated a sound taxonomy that classifies sounds based on sound characteristics using insights from a multi-phased research process with people of mixed hearing abilities. We then performed a qualitative (with 9 DHH people) and a quantitative (with a sound recognition model) evaluation. Findings demonstrate the initial promise of HACS for designing accurate and reliable human-AI systems.
