(To repeat again!) my reservations about that approach are only that it (a) is relatively difficult and time consuming to learn to do well, that it (b) has a strong "visual-auditory" bias in basic classroom "inter-diction," and that it (c) depends on associating approximation of motor control of sounds with auditory schema, mediated by color-coded symbols. In other words, the anchoring and keys to accessing anchored sounds are essentially visual-auditory, not haptic as in EHIEP. Our experience is simply that haptic-integrated anchoring is more efficient and accessible to instructors, especially for those with little or no previous training in linguistics and pronunciation teaching.
But don't take my word for it or Messum's. Get trained in the Silent Way so you can work with it in one class and see how it works . . . and then get the complete EHIEP system of haptic videos (which will be available in late Spring 2013) and let it train you and your students in 8, 30-minute weekly segments . . . Note: Versions of many of the basic EHIEP system haptic videos are linked off the blog in earlier posts. If you are interested in seeing some recent, pre-release stuff and perhaps field testing it in your class for us, let me know (email@example.com)!
