Seems marginally useful. When GitLab asked me for how my name is pronounced, I scratched my head and figured there must be some generator for such things, and ended up at NameShouts. They did generate pronunciations for my name, but not of a quality that I was able to just cut and paste; I had to tweak them to make them usable. I'd have been more impressed if they included a mechanism for suggesting improvements to existing entries, but there was none.
tl;dr? "Meh."
