I hear words in clips and phrases
Christina perri – the words [official video]
Then there was the dress that split the internet, with people all over the world debating whether the viral picture was clearly blue and black or clearly white and gold. (The color scheme was blue and black.) And there was the Yanny vs. Laurel debate, which was triggered by an audio clip of a computer-generated voice saying the word ‘Laurel’ in a deep male voice, or the word ‘Yanny’ in a higher tone, or both, depending on what you wanted to hear. (It was, by the way, Laurel.) The internet is now divided by the next big debate. The word you hear seems to rely on which phrase you read on the screen or even which words you are thinking about as you hear it, according to a TikTok video featuring a man’s voice saying either the word “brainstorm” or the words “green needle,” and the word you hear seems to depend on which phrase you read on the screen or even which words you are thinking about as you hear them.
The video, which was posted by TikTok user @emilysophie.m, has gone massively viral on the internet, racking up 5 million views in just a few days as people try to solve the audio mystery surrounding the clip, as Buzzfeed first mentioned.

We created a method that progressively increased the amplitude of different frequencies in the original audio clip. How far do you have to pass the slider to hear the other word or name? (The original recording is represented by the slider’s center point.)
High school students shared the clip and the original “Yanny or Laurel” poll on Instagram, Reddit, and other social media platforms, claiming that it was recorded from a vocabulary website and played via computer speakers.
A spectrogram, a form of chart that visualizes how the frequency of different sound frequencies changes over time, is one way to understand the dynamics at work. The word “laurel” is strongest in lower frequencies, while a virtual variant of the word “yanny” is strongest in higher frequencies, as seen in the spectrograms above. Both are shown in the audio clip.
Extreme – more than words (official music video)
Deutsch discovered the Speech-to-Song Illusion in 1995 when fine-tuning the spoken commentary on her CD ‘Musical Illusions and Paradoxes’1. She had the phrase “often act so oddly” on repeat and found that after a few repetitions, it sounded more like a song than a spoken phrase. Later, she included this illusion with the following commentary on the CD ‘Phantom Words and Other Curiosities’2:
Speech is made to sound like song in our final demonstration, and this is accomplished without changing the sounds in any way or introducing any musical meaning, simply by repeating a phrase several times. The demonstration is based on a sentence from the CD Musical Illusions and Paradoxes’ first track. When you listen to this sentence normally, it seems like it is being spoken normally, which it is. However, if you constantly play the phrase embedded in it:’sometimes act so oddly,’ something strange happens. The words seem to be sung at times, rather than being spoken, as seen in the diagram below.
A voice can be heard saying “green needle” or “brainstorm” in the video clip, which was posted on TikTok. The video instructs viewers to listen to the same sound bite twice, once while looking at a “silver needle” caption and again while looking at a “brainstorm” caption.
“The physical properties of the sound that is made each time a word is spoken are very different —this is due to physiological variations between different talkers, or different speech styles, and different listening environments,” Schertz explained on Thursday.
According to Schertz, one’s mind will easily move between the terms by thinking about the second term while listening to the audio file, allowing the ears and brain to lock on to the second perceived acoustic pattern after hearing the first word previously.
The audio clip was originally posted on Reddit by a user named’squidjeep’ in May 2018. The video shows a toy that says “green needle” or “brainstorm” when triggered. It was later discovered, however, that the clip was simply saying “brainstorm.”
