Audio-Based Interface

A computer interface that uses sound as the primary means of conveying information and supporting interaction, rather than visual display. Audio-based interfaces are essential for blind and visually impaired users and may employ speech output, environmental sounds, musical tones, earcons, or spatialized audio to represent objects, locations, states, and actions. These interfaces can support complex tasks including navigation, learning, gaming, and creative expression, and are particularly important in educational software for blind children where audio serves not just as an accessibility accommodation but as a medium for cognitive development.
