Reminds me of Neal Stephenson's "The Diamond Age: Or, A Young Lady's Illustrated Primer". Between all of the more typical cyberpunk, nanotech adventure stuff, there's quite a bit about how the "smart" toy (in this case, the Primer) influences development of the individuals using them. There's also a bit about the difference between users who were connected to a specific person doing the voice aspect and the users who got random staff or even automated "personalities".
