What a funny post you have here guys, the level is like to be in a bar drinking beer having a burp-jitsu contest.
Just kidding..
Seriously:
The only time I attended a seminar where the instructor teached types of sounds and what are they were intended for was in Maracaibo, Venezuela under Honorable Shihan Wagner Bull from Brasil. If I understood well he were studyng kotodama as he let us know in Aikido Journal forum months a go.
Maybe somebody wish to drop him an e-mail and kindly invite him to participate
