- Algebra Earcon (Mathematical Earcon, Math Sound)
- A non-speech auditory cue designed to represent the structural components of mathematical expressions, allowing blind users to perceive the overall shape and nesting of an expression without relying s…
- Audio CAPTCHA (Audio HIP, Audio Human Interaction Proof)
- An auditory alternative to visual CAPTCHAs, typically presenting distorted spoken letters, numbers, or words that users must transcribe. While intended as an accessible alternative for blind users, re…
- Audio-Based Interface (Audio Interface, Auditory 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 i…
- Audio-Based Navigation (Audio Navigation, Auditory Navigation)
- A navigation approach that uses audio output — typically synthesised speech, spatial audio cues, or sonification — as the primary means of providing wayfinding information to users. Audio-based naviga…
- Auditory Menu (Audio Menu, Speaking Menu)
- A user interface menu that conveys its content and structure through audio rather than visual display. Auditory menus typically use text-to-speech to read menu item names and may incorporate non-speec…
- Auditory Scrollbar (Audio Scrollbar, Sonic Scrollbar)
- A non-speech audio cue that conveys a user's position within a list or menu, functioning as an auditory analogue to a visual scrollbar. Auditory scrollbars use variations in pitch, tone patterns, or g…
- Auditory User Interface (AUI, Audio 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 interface…
- Aural Rendering (Auralization, Audio Rendering)
- The process of converting visual or textual information into a spoken or auditory representation. In programming accessibility, aural rendering transforms source code into speech output that conveys n…
- Hearcon (3D Earcon)
- An extension of the earcon concept that adds three-dimensional spatial audio properties to non-speech audio cues used in computer interfaces. While earcons are abstract synthesized sounds that represe…
- Non-Speech Audio (Non-Verbal Audio, Non-Speech Sound)
- Auditory output that conveys information through sounds other than spoken words — for example tones, clicks, earcons, auditory icons, musical motifs, or vowel-like timbres. Non-speech audio is widely …
- Pitch Polarity (Pitch Mapping Direction)
- The direction in which pitch changes correspond to navigation direction in an auditory interface — specifically, whether pitch increases (ascending polarity) or decreases (descending polarity) as a us…
- Reference Sonification (Audio reference tone, Origin tone)
- A sonification design pattern in which a fixed, recognisable audio tone represents a known landmark - typically the origin of a coordinate system or another anchor point - and can be re-played on dema…
- Spatialized Sound (Spatial Audio, 3D Audio, Spatialized Audio)
- Audio that is rendered with positional information so that it appears to originate from a specific location in three-dimensional space around the listener. Spatialized sound uses techniques like head-…
- Speech Dialogue Design (Speech Interface Design, Auditory Dialogue Design)
- The practice of designing the structure, content, ordering, and delivery of information presented through synthetic speech in computer interfaces. Effective speech dialogue design considers psycholing…
- Spindex (Speech Index)
- An auditory navigation technique that uses the first letter of each word (spoken or synthesized) as an index to speed up list navigation. When scrolling through alphabetically ordered lists like conta…
- Stereo Panning (Audio Panning, Pan)
- The technique of distributing a mono sound signal between the left and right channels of a stereo output to create the perception that the sound originates from a specific horizontal position in space…
- Structured Audio (Structured Digital Audio)
- Structured audio refers to digital audio content that has been encoded with hierarchical markers and metadata, allowing non-sequential access to specific segments such as chapters, sections, paragraph…
- Synthesized Speech (Synthetic Speech, Speech Synthesis, TTS Output)
- Computer-generated speech produced by text-to-speech (TTS) engines that convert written text into spoken audio output. Synthesized speech is the primary means by which screen readers convey on-screen …
- Unit Selection Synthesis (Concatenative Unit Selection, Unit Selection TTS)
- A text-to-speech synthesis approach that generates speech by selecting and concatenating variable-length segments of pre-recorded human speech from a large database to match the input text. Unit selec…
- Virtual Acoustic Environment (Audio Virtual Environment, Acoustic Virtual Environment)
- A computer-generated environment that uses audio as the primary medium for representing spaces, objects, and interactions, enabling users to navigate and interact with a virtual world through sound. V…
