This is great in many ways! This is Lucian's longest surviving work, and having audio versions of relevant writings is very desirable. I think they will be more helpful for “getting the word out” in the long term than written text.
Different voices for the different people in the dialogue are necessary, and this does achieve that well -- and, of course, giving robot-Joshua the winning side of Lycinus is appropriate. We associate Joshua's voice with accuracy and coming from our view-point. Brilliant!
The voices do not catch the sarcastic tone very well (the robot may not even fully recognize when the text is sarcastic). This undercuts the comedy a little bit, but otherwise the voices are great. THANK YOU!!
