I use the word "bark" too, albeit for a different purpose. I think that sort of spec selection is just a habit that you naturally get into when creating a lot of voice commands.

Incidentally, I've learned a bit of Korean, and it's caused me to notice that Dragon recognizes words which don't end in multiple unvoiced consonants more easily than those that do. (For example, "taze" is better than "taste" and "pad" is better than "pact".)
