assumption: on iBooks and Adobe Digital Edition the read-aloud of my ebook works.
I view the ebooks also with Huwawei Mate with Android and the Google Play Books App.
I know that the read aloud depends on the ebook reader, but then why read aloud
in Google Play Books works with fairy tales (ex: Tom Thumb) made by Rizzoli with PubCoder
and does not work with my epub?
I use the ultimate version of PubCoder for Windows.
The ebook epub file that I created and uploaded it in Google Play Books,
which does not work the read-aloud and in the controls on the top right of Google Play Books does not appear the "play" button (gray triangle) for start reading aloud.
In the fairy tales of the Rizzoli that "play" button can be seen and it is active.
Do I have to provide additional code? Or other?
