Certainly, thankyou for asking.
I would be happy to give narration a try and see how I manage, if that would be helpful.
So, this would mean reading the little section before the cast list and... everything in italics ?
Like "such-and-such picks up the phone" , "Marius exits" , etc ?
I have some files recorded for Marius and the Fourth robot, now.
Is it appropriate to have them sounding kind of robottish ?
I only realised after I had done them, that at least some of the robots are designed to sound extremely like a human (for example, Sulla is clearly some kind of advanced model with all of her fancy language modules and suchlike).
But she seems like a real "show model" ... both Marius and the Fourth robot seem rather less as though they are primarily designed as human replicants.
I have Marius sounding like a more natural sounding version of Readplease2000 voice emulation software.
And the Fourth robot sounds more like a vintage "robot narrator" type voice.
These are the files, now ready for PL.
