Behind The Pages: The Making Of A Talking Book (Café in Berlin EPUB3)
As an author of stories for language learners it’s always important to me to create materials that are both fun and useful on a day-today basis. So perhaps it will not come as much of a surprise that many of these works are based on my own experiences (and frustrations) of learning languages myself.
A couple of weeks ago, for example, in an effort to bolster my Hebrew reading-comprehension skills, I was delving into an Ephraim Kishon story and really wished that there was a way to have the text read aloud to me while I was parsing it. As you may know, modern Hebrew is written without vowels which can make the pronunciation of unknown words really tricky sometimes. This paragraph would read something like this:

Fun times, right?
The Bewildering World Of Talking Ebooks
Since I couldn’t force the publisher to integrate narration into the text, I decided to look into various ways of creating something like this for my own learning materials, since I have both text and the audio (each published separately) for many of my books. Ideally I wanted something where the ebook would mark each sentence as it was being read aloud and also allowing for tapping on certain sentences to hear them read.
Now, some of you might say: but Amazon already has something like that. No need to reinvent the wheel!
And it’s true. If you own the Kindle edition of a title and also have the Audible edition, Amazon will automagically bring them together as part of a feature called “WhisperSync for Voice”. Since most of my books are available on both Kindle and Audible, I thought it to be no big feat to just bring the two together.
Turns out that
a) Amazon doesn’t make this available for all titles,
b) the conditions for making it available are really opaque
Apparently the Kindle edition and the Audible edition need to be word-by-word duplicates, which makes sense since the app has to align the audio with the text but really is a bummer for books such as mine that contain extra text like vocabulary and exercises.
So Amazon and its Kindle devices & apps unfortunately were off the table.
Next, I started looking into the open EPUB standard, which literally everyone (except Amazon!) uses, and lo and behold – EPUB3 supports this feature called “Media Overlays”. I built a quick prototype (with the help of Alberto Pettarin‘s excellent guide), tested it on Windows Adobe Digital Editions and it was working!
Unfortunately, when I put the resulting EPUB on my iPad and tried to open it with iBooks, the narration was *poof* gone, non-existent. After a bit of research I found out that Apple apparently only supports narration for “fixed layout” EPUBS, not reflowable texts. Why, Apple?! The reflowable nature of ebooks is what allows for font-resizing and other customizations, whereas fixed layouts are like glorified PDFs, i.e. the amount of words and their format on each page are set in stone.
Open Standards For An Open World
So two of the biggest ebook ecosystems on the planet, Kindle and iBooks dropped out of the race before I had even really started. No biggie, right? But I liked the concept too much to just give up on it. I simply had to find a way to work around the giants and put this book into the hands of readers directly.
In other words, I had to come up with different user scenarios and find a solution which is the most comfortable for casual readers. So, Adobe Digital Editions works with EPUB3 overlays on PC, for example, but not on Android or iOS! In the end I found an excellent app called Menestrello, developed by Alberto Pettarin, which runs perfectly on iOS and Android and thus covers most of mobile devices. On Chrome there’s the excellent Readium extension, which catches most laptops and desktops.
However, I still wanted something simpler, something that people could just use immediately, without downloading or installing anything. That’s when I found that the same people behind the Readium extension also made an open-source web-app for embedding ePUBS directly in your browser.
So that’s what I settled on in the end:
- offering the EPUB as a direct download
- embed it in a “cloud reader” for immediate enjoyment
