Many individuals use verbal or non-verbal communication daily. Communication is very important when it comes to daily tasks. However, some individuals have a difficult time with verbal communication due to complications. Though sign language and other nonverbal forms of communication can be used, verbal communication is a direct and efficient method for communicating with others. Many studies have looked at the possibility of using a signal generated by vocal cord vibrations to generate speech. This would enable individuals all around the world to speak without moving their lips. From NASA News, Michael Braukus and John Bluck mention that

“NASA scientists have begun to computerize
human, silent reading using nerve signals in the throat that control speech”.

In their research, the device was placed “under the chin and . . . could
gather nerve signals . . . and send them to a processor and then to a computer
program that translates them into words” . Though this research was not
completed, other researchers have worked with this technology. In the article
“End-to-end Neural Networks for Subvocal Speech Recognition”, Pol Rosello,
Pamela Toman and Nipun Agarwala from Stanford University found that

“by measuring this muscle activity using surface electromyography (EMG), it may be possible to perform automatic speech recognition (ASR) and enable silent,handsfree human-computer interfaces”.

This device that could allow someone to communicate under their breath. This could be used for conversation in which they disclose private information. It could also aid individuals with disabilities that prevent them from communicating verbally. Because of this, we have decided to construct a device that allows for subvocal recognition. This device would consist of EEGs and a data acquisition device. The EEG would record the data and send it to the data acquisition device. The data would then be sent to a computer to be analyzed using a computer program. For this project, our goal is to have someone utter a certain set of words while the computer program produces the same results.
