Issues with exporting text to iTunes as spoken track

Hi,

On the latest OS, trying to export a highlighted block of text to audio, which it seems to do partially, but also kills voiceover in the act. I'm assuming the function takes over voiceover in some way to perform the act of creating the audio file... Anyone else experiencing the same issue... Anyone got a solution?

I'm turning one of my short stories into audio so I can perform it with it playing in my ear at a spoken word evening.

Cheers.
