I didn't realize this was an AI voice until some mentioned it, and complained. Glass half empty types. I had noticed a few irregularities in the Chandler audio, but figured it was a British thing. I have definitely heard narrations that I found a lot less pleasing than this.
I thought that the voice was real and I have a fine hearing ability, I write non fiction Really is AI? I AM REALLY ASKING. IF IT IS AI REALLY , THEN THEY MADE IT IT CAN (IN THEORY) IT CAN BE DONE . To speak is not the great thing. At least in common use. Great readers qualify by their gross style and emphasis and finally a question of personal taste of low level.
