Maybe I don't get what you want to express, but screen readers allow for alternative presentations of an HTML document, allowing for alternative modes of content discovery, e.g. hierarchical outlines of headlines and "landmarks". Several ARIA attributes further allow for communicating the current application state, e.g. whether content has changed (aria-live), a button is in a pressed state (aria-pressed), or a menu is opened (aria-expanded).
