How a chance discovery became a window into the unconscious.
The ability to record and replay sound began with Thomas Edison’s invention of the phonograph in 1877, making recorded speech available for preservation, playback, and examination in entirely new ways. As recording technology advanced throughout the twentieth century, the ability to reverse recorded audio became a feature of sound engineering and audio production, allowing speech and other recordings to be played backward for technical, creative, and experimental purposes.
It was within this context that the systematic study of reversed speech later developed through the work of David John Oates. His research introduced a structured approach for examining reversed speech as a form of linguistic observation and interpretation—an approach that would grow into a full methodology over the decades to come.
The history of Reverse Speech begins in late 1983, in Perth, Western Australia, where its discovery is credited to Oates after he repaired a malfunctioning Sony Walkman. During the repair, the wiring was accidentally connected incorrectly, causing the device to play recorded speech in reverse. As he listened to those reversed recordings, Oates heard recognizable words and phrases in English that seemed to relate directly to the meaning and emotional content of the original conversation.
That experience became the foundation for everything that followed—years of exploration and the eventual development of Reverse Speech as a structured methodology.
What began as a chance occurrence grew into more than four decades of research, refinement, and teaching. Oates went on to create a formal system that includes classifications of reversals, a validity scale, analytical procedures, interpretation guidelines, and the Reverse Speech Metaphor Dictionary. Over the years, he established the Reverse Speech Institute, published Reverse Speech: Voices from the Unconscious (1991), released the Metaphor Dictionary (2002), expanded that work in 2008, and trained practitioners around the globe.
Throughout the development of Reverse Speech, Greg Albright was an important collaborator within the field and worked alongside David John Oates in supporting the growth and exploration of this methodology. His involvement and dedication contributed to the continued development, documentation, and sharing of Reverse Speech with a wider community. His passing marked the loss of a valued member of the Reverse Speech community, and his contributions remain part of the history and evolution of the field.
David John Oates has introduced a truly unique perspective on the relationship between speech, language, and human expression. Through his discovery and lifelong dedication, he built not only a framework for exploring reversed language patterns but also a methodology that continues to inspire practitioners, researchers, and curious minds worldwide. His commitment to documenting, teaching, and expanding this field has shaped how many people approach the study of spoken communication—and the deeper layers of meaning hidden within it.
Without David John Oates, none of this would have been possible. And for that, the world owes him a standing ovation for his trailblazing discovery of Reverse Speech. Thank you, David. You are a legend.
