Sorry, but some things simply shouldn't have technology applied to them at this level. If author is so worried about trying to "automate" away parenting duties, I think they should take a good hard look at themselves in the mirror and seriously reconsider their approach to parenting.
There's no amount of RaspberryPi or Tensorflow to justify reducing parenting time so you can do more RaspberryPi or Tensorflow-ing.
The tone isn't great, but I think it's in part like that because they're trying to pitch their project as automation. To me it seems more replacing/extending something (analog baby monitor), but that's not exactly automation.
It’s up to the parent to move the speaker as they move to different rooms, as they can’t play the sound on any other existing audio infrastructure
