The HTML built by pretext will now come with a "Read-Aloud" button in the navigation bar.
Clicking it will show some player controls for a reader (or now listener) to have the content of the page read to them. They can navigate sentence-to-sentence with left/right arrow keys, or jump by paragraph with up/down arrows. Knowls will be skipped, but the listener can up-arrow back to them and hit space to hear their contents (or this can be done always if selected from the read-aloud settings).
Other settings include picking voices (depends entirely on the browser and operating system), reading speed, and whether to continue to the next page when reaching the end of one.
