  1. Whenever you intend to speak a word, your brain sends neurological signals to your throat muscles that allow you to actually say it out loud. However, this signal transfer occurs even if you think a word but decide not to say it. These signals are known as subvocal speech. Subvocal speech is part of the nervous system. Even in the event that a person's throat muscles are damaged to the point that they can no longer speak, subvocal speech signals are still sent from the brain to the throat. This phenomenon could prove useful in creating thought operation technology. For example, a developing system known as Audeo, created by the company Ambient, may help paralysis victims control computers and possibly even transportation devices without speaking a word or even moving a muscle.
