For Prospective Students: A starting point for further understanding of my work as an speech analyst/wellness practitioner would be to listen to some of the many interviews that I have given on this topic over the years.
This one from 2014 emphasizes the role of the mirror in studying reflections of audio waveforms:https://youtu.be/jiFG_drd7iw
My approach to practice is really founded in the yoga tradition where people are reported to use mirrors in aid of perceiving distant events across time and space.
The conceptual Maya Mukure (Mirror of the Goddess) is the magic mirror cited in this composition:http://sarkarverse.org/wiki/Maya_mukure_ke_ki_bhave_ki_kare
While my work is billed by others as "Reverse Speech" what is little understood is that I am simply practicing mirror meditation.
The refinement in my practice is such that I am able to produce iconic images of the Vedic avatars that resolve when the frames are mirrored:https://www.facebook.com/photo.php?fbid=10150759687596431&set=a.10150759687586431.390126.711561430&type=3&theater
The technical procedure across all hardware and software audio platforms is to reverse, mirror, or play backwards a recorded audio sample.
Beyond that, detection and interpretation occur within the scope of the observer's capacity similar to how musical talent varies from individual to individual.
The archetypes are understood through direct experience as they are "realized" within the consciousness of the observer at the time of contact.
David Oates, whose practices I thoroughly studied in the late 1990s, proposes an interpretative dictionary, something that Freud rejected at the introduction of Psychoanalysis in the early twentieth century.http://synchromysticismforum.com/hostedfiles/reverse%20speech%20dictionary.pdf
Oates also advocates the use of hypnosis in his procedure, whereas I find that the sounds of the messages are entirely inductive in and of themselves, similar to how the yogic mantra acts to expand consciousness.
The de facto objective of Oates's practice is to induce belief and acceptance within the mind of the participant of a "Reverse Speech" belief system, a fantasy world within which it is anticipated that the participant will discover their true nature/be liberated from their condition/know happiness etc.
A simple example of that indoctrinary orientation is the dictionary linked above that attempts to provide novel meanings for already-known language.
The object of my practice is to awaken the cathartic response/Self-knowledge within the participant by which they are empowered to succeed in achieving their life goals.
To replicate my results one would have to commit to walking the same path, spending time with the instructor and leaving behind much of what Oates proposes (material that is not viable in real-world practice at all).
The goal is to develop the consciousness that can exhibit these behaviors, not to memorize a bunch of dogma.
Instruction could take the form of teacher-student listening sessions with discussion conducted over Skype.
I hope that this information is helpful to your inquiry and I invite further conversation around these matters with you :)
