However, there is no evidence of its existence, and accepting this pseudoscience could prove tragic. In the past several years, a researcher named David Oates has been advocating his discovery of a most interesting phenomenon. Oates claims that backward messages are hidden unintentionally in all human speech. The messages can be understood by recording normal speech and playing it in reverse. His company, Reverse Speech Enterprises, is dedicated to profiting from his discovery.
Human speech has two distinctive yet complementary functions and modes.
The Overt mode is spoken forwards and is primarily under conscious control. The Covert mode is spoken backward and is not under conscious control. The backward mode of speech occurs simultaneously with the forward mode and is a reversal of the forward speech sounds. These two modes of speech, forward and backward, are dependent upon each other and form an integral part of human communication . . . Covert speech develops before overt speech.
