Quick answer
Use read-aloud with lecture PDFs when the material is mainly text and you can still check the page when needed.
Do not rely on audio alone for diagrams, equations, complex tables, or material that needs close visual inspection.
Start with a short section
Choose a normal voice and speed. Listen while watching the active text for a page or two.
Pause at structure changes
Stop at headings, figures, tables, or difficult passages and look at the page.
Audio is a support tool, not a replacement for every kind of reading.
Keep your place
Use a reader that keeps the active passage visible and saves progress when you pause.
Offline tip
Download any required voice before travel and test it in airplane mode.
If the first fix does not work
Try another known-good lecture pdfs example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
