Hyfe is designed for individual users. High performance means detecting all coughs from a nearby user and no ambient coughs from others in the distance. To achieve this, Hyfe uses various metrics to sort out the soundscape it is analyzing, filtering to loud noises that are potentially robust coughs from a nearby source. In the real-world, however, these circumstances are never binary. The intended user will be various distances from their phone and will be moving through various soundscapes.
