Imagined speech

Imagined speech (also called silent speech, covert speech, inner speech, or, in the original Latin terminology used by clinicians, endophasia) is thinking in the form of sound – "hearing" one's own voice silently to oneself, without the intentional movement of any extremities such as the lips, tongue, or hands.[1] Logically, imagined speech has been possible since the emergence of language, however, the phenomenon is most associated with its investigation through signal processing[2] and detection within electroencephalograph (EEG) data[3][4] as well as data obtained using alternative non-invasive, brain–computer interface (BCI) devices.[5]
