Does anyone know how I could turn text to audio files using ue4?

Does anyone know how I could go about turning text such as e-books into a audio recording like a audiobook, could you make a algorithm or some such program, that would read the text and turn it into a somewhat smooth audio recording? if not can someone give me some ideas on how I could do that, I am open to collaborations, as to make a cheap way to make my own audiobooks, without using my own voice?
