Start by testing two adjacent pages
Before preparing a long chapter, try two consecutive pages. Listen to the end of the first and the beginning of the second to see whether the meaning connects. A single page sounding good does not establish that the entire document will preserve a comfortable reading order.
Inspect Text on both pages, especially when a sentence continues across the boundary. Running chapter titles, page numbers, and footnotes can enter a sentence that should flow uninterrupted. Reviewing these lines early is worthwhile before spending a longer session preparing a complete sequence of spoken material.
Enable continuation after checking the source
Choose a starting position and a voice matching the language, then enable continuous listening to proceed through subsequent pages. If you want to follow visually, use page turning with the audio. These choices support related but different needs: keeping the listening session moving and following the page position.
Continuous reading is not a promise of a perfect automatic conversion for every PDF. Scans may need OCR; tables can require visual inspection; an illustration-only page may have nothing to narrate. Knowing the book’s structure helps you select a range that will actually be useful to hear.
Separate audio playback from new generation
Completed audio can keep playing when you lock the screen. Generating new speech requires the app in the foreground on iOS. If you are about to pocket the phone, prepare the material first instead of expecting continuous mode to finish every remaining page as a background task.
Test continuation with the actual book, voice, and device you intend to use. Text length, available memory, and remaining storage affect the work. There is no single preparation-time figure that is reliable for every chapter and every iPhone, so a small realistic trial is more informative.
Plan around one listening session
Choose a range for a specific purpose, such as the section you want to hear this afternoon, rather than your entire library. A modest preparation job that you have checked carefully makes repeated passages and ordering problems easier to catch than a very long untested list of pages.
Free has batch preparation and other limits displayed in the app. Pro removes the corresponding limits, while both editions use the same speech technology. Whichever edition you choose, the real content and useful chapter boundaries remain the best basis for building a longer continuous listening session.
