For people who haven’t yet seen how useful an EPUB3 (with Media Overlays) could be, I’ve made quick screen recordings, using
Menestrello on my Android phone and
Thorium Reader on my Linux desktop:
I’d so much wish that at least
Calibre, and maybe
KOReader, would support this—and more publishers use that format, instead of including dumb "download audio files here" links in their e-books… Earnestly, who would want to download and unzip a bunch of MP3 files, manually look up things like "Chapter 01 - Lesson 3.mp3", start a media player and jump around in the file just to hear the pronunciation of a word?
When it could be so easy!
EPUB3 w/ media overlays could be such an improvement for language learning, children’s books, etc.
Still, it appears that for now about 8 years, nobody in the publishing scene even
cares. Even Alberto Pettarin, developer of
Menestrello and the
Penelope dictionary converter, seems to have given up in 2015.
