Not sure if you have tested with VoiceOver on Mac OS X, but it looks like your document language was set to `es`, which uses a spanish voice when possible, making the content difficult to understand (because it assumes that it is in spanish).
That's right, I missed that detail, thanks for pointing it out :-)It should be fixed now, but I'll try testing my project with VoiceOver again to see if I can figure out how it works.
