Audio in a Bible Module

In a non-scripture book, such as a Bible Module, how does the audio timing work?

It seems like typically the timing works based on a \v verse marker, and then knows a little about how to break down phrases under that.

But what if the file doesn’t have \v markers at all? Is there a way to align the audio with paragraphs, or sentences? Or in this case do people just manually put \v numbering into the source file, but then hide it from being displayed?

You don’t need \v markers for the audio synchronization. In the Aeneas wizard, you can select “phrase by phrase” and then you define the punctuation markers that you want to use as the end of the phrases. It should work like this.
I don’t think paragraphs work per se as the boundaries for the syncing. What you could do is to add hidden characters e.g. zero width whitespace to your text, and then define them as “punctuation characters” in the Aeneas wizard. It should work.

M James, How are you doing getting synchronization of your non-scripture content? Do you need further help?
