A New Theory About Language - By David John Oates

Have you heard the news?

I’ve just released my latest book - ‘A New Theory About
Language’ the 2015 edition!

And I have to say… I’m extremely proud of it

Over the last 30-years Reverse Speech has, as a result of constant
research and testing evolved and developed, often beyond my own
expectations, to become what it is today…

And in this book I reveal for the very first time, the results of my
latest research on the subject.

Research I haven’t shared before, that will advance Reverse Speech
and propel it toward my dream of it being embraced by the entire
scientific community…

The Insiders - We Know What You're Thinking and The Truth Will Be Told - By Kathleen L. Hawkins

Bestselling author and Reverse Speech student Kathleen L. Hawkins just had her first novel THE INSIDERS published. It’s the first in a series in which her characters use Reverse Speech to solve murder mysteries, discern hidden motives and agendas, and gain insights into human behavior.

Kathleen studied Reverse Speech for three years with David Oates. During that time she used reversal analysis on an actual recording of a police interrogation of a suspect who was later found guilty of murder. The suspect’s reversals revealed how he committed the crime and where he hid the body. Kathleen weaves those actual speech reversals into a fascinating, fictionalized story that’s a thought-provoking psychological thriller about a group of teenagers who solve a murder mystery using a “mind-reading machine,” the Reverse Speech technology.

Kathleen was one of the first students to earn a Reverse Speech Investigator certificate.
