This is a great idea and it's thoughtfully executed. I love the concept that there can be just one place to store a way to teach people your name. I try hard to get the name right when I meet new people and it can involve a bit of back and forth if the name is new to me, and sometimes I then forget and have to ask again in a future conversation. The implementation of the slowed-down version of names is nice too, it slows down without reducing clarity.
