In many EVP videos in which people find "spirit voices" in real life, such as in the video above, one tactic is using sounds which may sound like words, and then using text to make people hear certain words. The result is that we may actually hear the words from the sounds. In a test, I watched the video, seeing all of the text and hearing all of the noises, while my roommate only heard the video. I could hear the words that appeared on the screen, but my roommate only heard sounds that were sometimes words and sometimes just random noises. She never heard the words that appeared in the video.
