Proposal - Hyper Audio Markup Language for Enhanced Audio Navigation
Digital text is inherently two-dimensional: readers can glance, skim, scroll, and follow hyperlinks. Digital audio, by contrast, remains fundamentally one-dimensional, requiring listeners to proceed sequentially. This limitation makes long-form audio - podcasts, audiobooks, lectures - difficult to navigate, and it is especially challenging for blind and low-vision users who rely heavily on audio interfaces.Although chapter markers, transcripts, and voice assistants have improved accessibility, there is still no standardized mechanism for hyperlink-like jumps within audio itself.
To address this gap, I would like to propose a concept I call Hyper Audio Markup Language (HAML) - a lightweight, open approach that enables listeners to jump directly to relevant segments using simple voice commands.
Key elements of the proposal include:
- Embedded audio signals: The audio file contains brief, unobtrusive tones (e.g., short “hik” sounds) that indicate the presence of a hyperlink.
- Linked timestamps: Each signal corresponds to a predefined timestamp or section, enabling contextual jumps, footnote-style references, glossary lookups, or supplemental detail.
- Voice-activated navigation: When the listener encounters such a signal, they may say a command such as “go”, prompting the player to jump immediately to the linked segment.
Rather than seeking a patent, I intend to make this concept open-source. I have reached out to a few organizations working on the audio technology and accessibility innovation.
This invention introduces a buccal cavity washer, mainly consisting
of an assembly of an Enclosure, a Motor, a set of Pipes, and a set
of Tanks, to automate the process of rinsing and washing the buccal
cavity.
This invention relates to electrically swinging fans which consume
less electricity for producing a desired cooling effect, produce
tangential hygienic airflow, produce ceiling-independent comfortable
airflow, and do not create vibrational stress on the ceiling.
