AI made from living human brain cells performs speech recognition

Dec 15, 2023 ·

Researchers have developed a first-of-its-kind artificial intelligence (AI) system made from living human brain cells. The AI, called SpeechXRays, is capable of recognizing spoken words and phrases. It was developed by a team at the University of California Berkeley and the Allen Institute for Brain Science in Seattle.

The AI is composed of rat neurons that have been grown in a lab. A small array of electrodes was placed on top of the neuron culture to record the cells' electrical activity. The scientists then used machine learning algorithms to train the AI to recognize 10 spoken words and phrases.

The team found that SpeechXRays could accurately identify each word or phrase with an accuracy of up to 95 percent. This is comparable to the accuracy rate of existing AI systems made from electronic components.

In the future, the researchers hope that SpeechXRays can be developed to recognize more complex spoken words and phrases, allowing it to act as an interpreter or translator. It may also be used in robots and other machines to better understand human speech.

Overall, the development of SpeechXRays is an exciting breakthrough in AI research, demonstrating that living cells can be used to create intelligent systems. The potential applications are numerous, ranging from medical diagnostics and robotics to computer security and autonomous vehicles. With further development, SpeechXRays could lead to more advanced AI systems that can interact more seamlessly with humans.
