Book Narration with Images: Why the Cover Is Not Read
When a book is narrated, its images do not become spoken descriptions. TGRadio extracts available text, but it does not recognize lettering inside pictures or explain illustrations. If a cover or diagram contains essential information, manually include that information in a text copy before importing the book.
Check where the lettering is stored
Open the original book and try selecting the cover title separately from the picture. If only the whole image can be selected, the lettering may be part of that image. In a PDF, also try copying several words into a plain text editor. Visible letters do not prove that a matching text layer exists.
Check the title page separately. The same title may appear there as ordinary text even when the cover itself is an image.
Separate captions from picture content
A caption beneath an illustration and labels inside it may be stored differently. For example, “Figure 3. Lock mechanism” may be text, while the names of parts remain embedded in the drawing. Hearing the caption does not give the listener an explanation of the mechanism. Compare each important image with the surrounding paragraph.
If a passage says “as shown in the figure,” identify exactly what information the reader is expected to see before deciding what to add.
Describe what the listener needs
For a decorative cover, the title and author may be enough if you want them read at the beginning. For a diagram, explain the relationships between its elements. For example: “Water enters the upper chamber, then passes through the gate into the lower chamber.” You must write this description yourself. TGRadio does not analyze the picture or verify your explanation.
Keep visible information separate from guesses. If a label is unclear, find a sharper source before supplying a possible meaning.
Add explanations to an external copy
Edit a separate file outside TGRadio; the app has no built-in text editor. Place the description beside the paragraph that refers to the image. If useful, introduce it with “Figure description.” Keep the original book so that details omitted from the listening copy remain available for visual reference.
Avoid pasting a table or formula as an unexplained string of symbols. If you can accurately express its meaning in words, write a coherent explanation. Otherwise, reserve that passage for consulting the original.
Check the passage without the picture
Read your prepared passage while looking away from the illustration. Object names, directions, and references such as “on the left” should make sense. After importing, select the book and press Play, then compare an available audio passage with your prepared text. Adding the file alone does not prepare audio for the entire book.
If the caption is audible but the explanation still depends on seeing the drawing, add the missing details to the external file. Changing the voice cannot supply an absent description.
