Third post now, but I'd like to see a kids' game built around schemas ("up", "down", "on top of" etc) that uses voice recognition to promote and reward speech in young children. My specific use case is children like my son, who are mostly non-verbal but who can occasionally muster the words to ask Alexa for a song (or badger me for chocolate). Games are a great way to tease more language out of kids like him, but there aren't many that fit.
