I made a similar system but for music, using QR codes on plastic cards and a webcam, when my daughter was 1. After a year or so we switched to just having a standalone numkey pad where she could just punch in numbers from a jukebox-style catalog. https://github.com/dmd/nkplay/
She's now 10, and knows ~100 playlists by number. "I want to listen to 37!"
Your numpad solution looks great! Would you have a photo of the whole setup? I thought about doing the same, but I fear to end with cables and PCB everywhere in my children's room if I take this path :)
There's honestly nothing really to see. It's a raspberry pi in a standard plastic case[0] with 3 cables coming out of it - power, usb to the numkey, and audio (male to male headphone jack) to the speakers.
The pi and power are hidden behind a bookshelf, so all that is actually visible is the numkey and the speaker.
