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. One mode cannot be fully understood without the other mode. In the dynamics of interpersonal communication, both modes of speech combined communicate the total psyche of the person, conscious as well as unconscious. Covert speech develops before overt speech.
Children speak backwards before they do forwards.
Then, as forward speech commences, the two modes of speech gradually combine into one, forming an overall bi-level communication process. Technological Description of Reverse Speech Reverse Speech is another form of human communication that is automatically generated by the human brain. It occurs every time we speak and is imbedded backwards into the sounds of our speech. This previously undiscovered function of the mind is the mind's own independant voice speaking from the deepest regions of consciousness. This form of communication can be heard if human speech is recorded and played backwards.
