Yeh I think I understand now. The filename of each file in the resources folder represents the hot-word that's detected. When you specify multiple files it'll give the index corresponding to the file and hence the word that was detected. So the problem is that since you don't support generating your own hot-words for raspberry pi, you are stuck with the small random set of words in the repo. That's kind of a huge limitation. So while I'm sure this is a great project for use with x86 and mac, it's a non-starter for me. Presumably proper support for raspberry pi is coming at some point so I'll be sure to check back.
