Scientists Found a Way to Convert Human Brain Signals Directly Into Speech

Written by vengreat

Scientists from Columbia created a device that converts thoughts into smart recognisable speech.

By tracking the brain activity of someone, some harnesses which have the power of speech synthesizers and artificial intelligence, may lead to new ways for machines to interact with the brain directly.

The Journal of Neuroscience now includes a report on the research.

The team foresees the system using the brain’s own sound encoding together with the instructions that control the muscles in the mouth, tongue, palate, and voice box,

“Our voices help connect us to our friends, family and the world around us, which is why losing the power of one’s voice due to injury or disease is so devastating,”

says one of the team, Nima Mesgarani from Columbia University in New York.

Not More Complicated than Hawking Technology

A 76-year-old great theoretical physicist Stephen Hawking had died earlier. Hawking spent most of his life in wheelchairs, had a rare disease called amyotrophic lateral sclerosis, which left him crippled and unable to talk normally for most of his life.

Thanks to the computer interface that he could manipulate by moving his head. He could also write words and sentences that a speech synthesiser would read out then !

Based on their results, they are now planning to build an algorithm for the brain-machine interface that will also be able to form words and sentences by combining them, as well as decoding gestures.
