Researchers from Japan Toyohashi University who are majors in Technology said that they can accurately recognize numbers from 0 to 9 by means of brain waves. They tested the study and surprisingly, what the participants said were guessed by the robots in real-time based on readings of an electroencephalogram brain scan. When they tested it again, it resulted to a 60% accuracy rate for recognizing 18 types of Japanese symbols from EEG signals. They said that there is a possibility that they will be able to produce an EEG-activated typewriter in the years to come. In one of the university’s statements, it said that they are having a hard time collecting enough data to permit the use of a powerful algorithm that is strongly based on deep learning or other types of machine learning for speech decoding from EEG signals.
They are still in the process of improving their research and framework that can result to higher performance but still in a small training data set. With the group’s aim to create a brain computer interface, this technology may be able to assist handicapped people who do not have the ability to communicate. The brain computer interface will be programmed to recognize words without having to physically talk to a person in the form of speech or voice. This is by far the most amazing technology there is, it will enable those who cannot speak to have the ability to do so. The research group also plans to develop something that can be easily operated with fewer electrodes and even aim to connect to smartphones in the upcoming years.
The scientists at the UC Berkley managed to replay a word that someone was thinking by means of monitoring their brain activity. The teams are currently studying how the brain areas overlap when hearing words, speaking out loud and imagining words. The research has a very long way to go because part of their goal is to be able to help those that are victims of stroke and other diseases that have speech problem. It is very challenging on their part to produce comprehensible speech from direct brain recordings while the victim is still contemplating the word he’s likely to say.

According to Professor Knight; “The goal of the device is to help people affected by motor disease such as paralysis and Lou Gehrig’s Disease. Apart from these diseases, there are a lot of neurological disorders they can help with this technology. They want to create an implantable device that can interpret the signals that transpire in the brain when they think about a word and then turn these signals into a sound file that can be replayed by a speech device.” This is indeed a very unique device since it can turn someone’s thoughts into words by means of an electronic speaker or a writing device. The inventors have also created a computer model that could match words that come out from people’s mouths which later on will be translated through signals.
