Bubute, the audio box children can operate themselves

Field notes

Bubute uses physical illustrated cards as the interface: a child inserts one into the player, which then delivers 15–60 minutes of Spanish audio. The proposed starter set includes five cards selected from six families, spanning bedtime, stories, music, word games, questions, and spoken-response activities. The page says the device will include a 2.4-inch screen, USB-C charging, and controls for volume and tracks, while also noting that the hardware remains in development.
