Query: Needs text-to-speech enabled

I will not buy this book for my Kindle because the publisher decided not to enable the text-to-speech option. I work with low vision and blind people. I recommend the Kindle to them because of the text-to-speech adaptation. When book publishers don't allow this feature it makes the book inaccessible to the low vision and blind population.
