Speech-to-text: How do I correct a learned word?

[AC Question]

So, my phone has mis-learned what I want it to type when I speak a particular word. Most annoyingly, it's the name of my business, which I say all the time.

For example, my phone used to correctly recognize, "Xyz LLC." It now dictates the same phrase as "xyzllccom." That is most probably because it's a bastardization of website's URL. Anyway, how do I fix it?

Thanks,

Steve
