A study published on PLoS Biology called ‘Reconstructing Speech from Human Auditory Cortex‘ has made the initial steps in converting brain activities into audio. Using computer algorithms, the research revealed how thoughts can be decoded, reconstructed, and played back in sound.
The technology still has a long way to go, but provides a glimpse of what the future might hold. For example, computers might be able to read our minds entirely to perform functions accordingly. The technology can also be used to assist people with speech impairment.
Watch the video to see the device sound out words from recognizing various brain activities. The words are: Waldo, structure, doubt, and property.
