I am very confused about Snips.ai

I got the add-on to work. Sort of. It listens to my voice and I can see the transcribed text in the logs. But I have what you’d call a flat Midwestern accent, which shouldn’t be too hard for a robot to understand, and there seem to be lots of words it doesn’t understand. Like “studio” and “weather”. In the logs they are replaced by “unknownword” or something like “store veal” or “water”. So, maybe I need to train a new assistant, but I’m also really confused on how to do that.

Does someone have, like, a really tedious video or tutorial or something?
