The point is not that the children cannot listen to books but the bonding ritual that is reading to a child. Hearing the stories they like to hear. Having them ask for a specific one. Singing your child to sleep as well - you can still play music but the act of them watching you sing and hearing your voice is important.

Go listen to a Tonee or whatever when you get home from school while I'm making dinner and let your imagination run wild to Gabby's Treehouse audio books but I'm reading Cinderella tonight.

If we're just talking about that specifically then actually it might be quite good to have an audio book that uses the parents' voice, if we ignore privacy concerns about cloning your voice.

But the context of the post is saying more than that. They're talking about not spending time with the child and reading to them, which I think most people disagree with. Just as I think most people would disagree with just giving a child an audiobook instead of reading to/with them, irrespective of whose voice is being used

Children need parental bonding.

Also, an audio book wont assist in helping the child learn to read.
