IIT Madras Develops AI Technology For Converting Brain Signals Into English Language

1 Mins read

In what sounds like something straight out of a sci-fi movie, a research team from IIT Madras has developed a breakthrough technology to read a person’s thoughts and convert them into written language.

In the past, Elon Musk’s Neuralink and Mark Zuckerberg’s Facebook have conducted similar research to develop a brain computer interface, but it’s good to know that IIT Madras already has results to show, where others might’ve been less successful.

The breakthrough research team was led by Dr. Vishal Nandigana, Assistant Professor, Department of Mechanical Engineering, IIT Madras.

Using AI technology, Dr Nandigana claims the thought to text solution can help speech impaired individuals communicate better, while the technology can also be used in decoding natural phenomenon — chemical signals in plant that are responsible for photosynthesis process, and more.

How it’s done

Whether it’s decoding nature’s signals in plants or our own brain’s signals that control our existence, ultimately it all comes down to unraveling electrical signals or physical waveforms. Our brain fires up neurons that result in electrical signals and ionic current flowing through certain parts of the brain that can be interpreted as human language or speech.

“This would tell us what the ions are trying to communicate with us. When we succeed with this effort, we will get electrophysiological data from the neurologists to get brain signals of speech impaired humans to know what they are trying to communicate,” according to Dr. Vishal Nandigana of IIT Madras.
