Yes, I'm certain this can be done by modifying the script. I'll see if I can solve it later today.

You could break the audio and text file into corrosponding chunks and run the python script for each chunk, I was thinking about making the script do this for you if you specify the chunks so you don't have to run the python script for each chunk.
