Re: phantom words demonstrations
Just a small gloss; I used to use this Phantom Word effect on my
students (DSP/Music computation) with amazing results; students
reports "Let them die", "Mine's a beer" and many disparate words.
Quoting Diana Deutsch <ddeutsch@xxxxxxxx>:
As Bruce mentioned, I do have ?Phantom Word? demonstrations on CD ?
one on my CD ?Musical Illusions and Paradoxes? and six more on my CD
?Phantom Words, and Other Curiosities? (see my ?Phantom Words? page
under ?Illusions and Research? in http://deutsch.ucsd.edu - this
contains a description of the phenomenon and also links to a number
of sound examples). The listener sits in front of two loudspeakers,
with one to the left and the other to the right. Each track contains
two words, or a single word composed of two syllables, and these are
repeated over and over. The same sequence is presented through both
speakers, but the tracks are offset in time so that when the first
sound (word or syllable) is coming from the speaker on the left the
second sound is coming from the speaker on the right, and vice
versa. People initially hear a jumble of meaningless sounds, but
after a while distinct words and phrases suddenly appear. The effect
is often so vivid that people may become convinced that different
words and phrases have been inserted into the track, despite my
insistence to the contrary. As I describe, ?phantom? words and
phrases are often related to what is on the listener?s mind. I also
describe and discuss this effect in my blog for Psychology Today at
http://www.psychologytoday.com/blog/illusions-and-curiosities/200906/phantom-words In his book ?Rorschach Audio: Art and Illusion for Sound? Joe Banks describes this effect and relates it to the visual Rorchach
Historically, I discovered this effect when I was exploring the
possibility of obtaining something like the octave illusion with
verbal material using headphones. This didn?t work well, but I
discovered by chance that when the words and phrases were presented
via loudspeakers rather than headphones these striking illusions

Diana Deutsch has a CD that includes a "Phantom Word" demonstration
that sounds related to what you are describing.
Different words are perceived while listening to a repeating sound pattern.
I think what is heard is in the signal, but variations in
perceptual grouping over time causes different words to "appear."

Subject: Does anybody know a similar study?
Dear list members,
yesterday I colleague played me a sample (a sentence) of highly degraded
speech. It was a recording made in a highly noisy environment. It
included speech (a conversation) that was hardly intelligible except for
a few occasional words.
The colleague asked me to listen to the sample and pay attention whether
I was able to spot a few target words. These words were not intelligible
The colleague then selected a portion of the recording and played it in
loop. That portion included (according to him) one target word. After a
few loops I was able to "perceive" the word.
This is exactly the problem. I'm wandering whether it was just a
suggestion due to the repeated listening of an ambiguous auditory
signal. A kid of auditory Rorschach test: there seem to be nothing at
the beginning but if you keep listening you can hear whatever you like.
Is there anybody out there that is aware of studies that investigated
whether listening in loop to an ambiguous signal can lead to hear things
that are not in the signal?
I didn't find anything yet.
Thank you all in advance,
