I use the app AnkiDroid on my HTC One to learn Italian. It has a text to speech option which, when enabled, reads the text on the flashcards aloud. However, after updating to Android 4.3, this function has become extremely erratic - only 1 of every 20/30 cards is read out (it worked perfectly before the update).
I have also recently bought a Google nexus 7, running Android 4.4.2, and it also has the same issue. Does anybody have any ideas about why this is happening and if possible how I could resolve this?
