Reverse Speech is the phenomenon of hidden backward messages in speech. It's been pretty much rejected as bunk by the scientific community, but given the wealth of audio examples available, I believe the phenomenon is real. Its advocates theorise that it is a form of unconscious communication both with oneself and with others. If true, it may reveal hidden truths that the speaker fails to reveal in normal forwards speech. David John Oates is at the forefront of research into speech reversal. http://reversespeech.com/reversals/ Here is some extracts of the 3rd presidential debate that have been reversed and analysed. Some may disagree with the translation and/or the interpretation.
