Here's a weird one:
I have been using and LOVING NaturalReaders Online, to listen to my ebooks. It's a (expensive) miracle! I far prefer it to audio books, which I find over-performed, often to the point of hurting the experience of the text.
The TTS treats all white space as a pause, so when the sentences break across a page, it inserts a weird pause in the middle of the sentence. I am wondering if there is any clever way to get calibre to force page breaks only AFTER a period.
I'm guessing probably not, but miracles do seem to happen in this software--
