Within the studies to help people who have communication problems, the song Another Brick In The Wall Part 1 by Pink Floyd has been used for such an excellent and laudable initiative.

Here you can read an article that explains this study of Science Orf

"Enormous progress has been made in recent years in programs that translate brainwaves directly into speech – i.e. that can read minds, so to speak.

A model presented just this year actually generates complete sentences from brain waves.

Such interfaces should one day help completely paralyzed people to continue to "talk" to their environment.

However, the sound of the voice output is usually quite mechanical.

Emphasis, intonation, and rhythm—all elements essential to the expressiveness of spoken language—have received less attention until now.

The work just published in the journal "PLOS Biology" could now make an important contribution to this.

The researchers led by Ludovic Bellier from the University of California, Berkeley have also succeeded in decoding musical elements from brain waves.

The ten-year-old data comes from 29 epilepsy patients who had electrodes in their brains as a result of an operation.

At that time, among other things, the brain activity was recorded while the test subjects listened to about three minutes of "Another Brick in the Wall, Part 1", a hit by Pink Floyd from 1979.

The reconstruction, which was also possible with the help of artificial intelligence, sounds It's not perfect, but it's recognizable: the text is a bit washed out, but the rhythm is generally right.

According to the team, different brain regions are active when listening to music compared to speech.

As part of the decoding of the brain waves, new areas were also identified that are responsible for rhythm and certain vocal elements.

According to the study, while speaking and understanding mainly take place in the left hemisphere, musicality is distributed, with more regions on the right being involved.

So far, "mind-reading programs" that deliver usable results still need a direct interface to the brain.

According to Bellier and Co., such implants are only an option for people who absolutely need them, such as people who are completely paralyzed.

However, it is assumed that non-invasive techniques will also improve.

Although individual letters can currently be recognized in recordings of the brain waves from the outside, this takes at least 20 seconds."
