If human speech is recorded and played backwards, mixed amongst the gibberish at regular intervals can be heard very clear statements.
As the human brain constructs the sounds of speech, it forms those sounds in such a way that two messages are delivered simultaneously. One forwards, which is the conscious mind speaking, and the other in reverse, which is the unconscious mind speaking.
On the surface level, it can act as a sort of Truth Detector as Reverse Speech will usually correct the inconsistencies of forward speech. If a lie is spoken forwards, the truth may be communicated in reverse. If pertinent facts are left out of forward speech these may also be spoken in reverse. It can reveal hidden motive and agenda and other conscious thought processes.
Some interesting audio examples from famous speeches are provided:
- From Arnold Schwarzenegger’s Governor acceptance speech: “Soon I’ll beat the law“.
- Armstrong’s words, “That’s one small step for man” reverses to say, “Man will space walk.”
I was hesitant about classifying this as science.
