Hi all,
as I’ve said in the title, I was carried away by the challenge and I kept building features over features. The VocalTextEdit now has the opportunity to read in 2 languages, increase the size of text from the menu, undo and redo functionality, a check button to allow the voice to tell you how many words are in the text and a pause/resume button.
There is something that keep me banging my head on the wall:
When I choose English voice Alex the pause/resume feature works like a charm but when I use the Italian Alice voice it seems that the didFinishSpeaking got called anyway. I’ve tried swap the code between the 2 voices with no luck. I’m baffled. I’m sure that is something right in front of my eyes but I can’t quite figure out what it is and I hope that someone of you, more experienced coders, will point me towards the solution. To be more precise if I use the Italian voices(female and male) and I pause during the reading after a second of pause the didFinishSpeaking got called and it stops

Maybe it could be a bug?
