So I found a teacher on Italki and sent him the first of these recordings. I found a male with good standard pronunciation who is not very expensive. I told him i didn't want a lesson, but rather use the time to listen, correct any grammar, vocab or pronunciation mistakes. I also asked him to send back a recording of him saying the same (corrected version) dialog in his natural speaking voice and normal speed. I will then use this to shadow and work on better sentence intonation, speed, etc.
