I hadn't actually when I originally wrote this comment as I wasn't somewhere that I could listen to audio (without being an obnoxious cunt and I won't be one of those people even if the majority of people seem to be OK with it xD)

However I would agree, I couldn't listen to a whole book with this monotonous drone of a voice, however like you said compared to what was produced by voice to text type systems of the past this is miles ahead and I certainly look forward to the technology progressing to a point where it is listenable for me.

I agree with good voice actors being essential for enjoyment, I think that is one of the reasons I fell in love with graphic audio productions over the last couple of years.
