Auditory User Interface

A user interface that relies primarily on audio output — including synthesised speech, earcons, auditory icons, and sonification — to convey information and enable interaction. Auditory user interfaces are essential for users who are blind or have low vision, and they can supplement visual interfaces in situations where a screen is impractical. Unlike simple screen reader overlays, purpose-built auditory interfaces are designed from the ground up to present information in ways that are naturally comprehensible through hearing, using techniques like voice differentiation, spatial audio, and structured audio cues.
