As a person who’s name is often a challenge to say, I really like the idea of being able to send people to this site or link in my personal site to be able to make the right pronunciation. It helps me and it helps them.
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.
