AI-narrated audiobooks are here – and they raise some serious ethical questions

Meet Madison and Jackson, the AI narrators or "digital voices" soon to be reading some of the audiobooks on Apple Books. They sound nothing like Siri or Alexa or the voice telling you about the unexpected item in the bagging area of your supermarket checkout. They sound warm, natural, animated. With their advanced levels of realism, Apple's new AI voices present the genuine possibility that the listener will be unaware of their artificiality. Even the phrase used in Apple's catalogues of digitally-narrated audiobooks – "this is an Apple Books audiobook narrated by a digital voice based on a human narrator" – is ambiguous.
