1. SPEECH PROCESSING AND BRAIN SIGNATURES OF SPEECH, PARTICULARLY IN DISTINGUISHING TRUE/FALSE OR YES/NO RESPONSES  Speech processing can refer either to a device that receives and interprets speech then performing a command in response or a machine that interprets brain wave signals related to thoughts of speech then performing a command.  The brain quickly interprets speech; this includes understanding a statement based on semantics, grammar, and intonation (Buzo ). Goal is to create a machine that can do the same and allow LIS patients to communicate effectively.  There’s little difference between the psychophysiological responses and brain signatures of an objectively true statement and those of a delusional (subjectively true) statement. (Langleben )  The brain shows increased activity to noises that have pitches or are decibels outside that of everyday speech. (Zatorre )  Through the processing of brain signatures through BMI (or BCI) to a speech synthesizer, individuals in a locked-in state can form speech and potentially engage in verbal conversation. (Guenther )

2. To create these communication devices, the first step is to create binary communication devices though the processing of Yes/No thinking. This is done by first semantic classical conditioning cortically evoked responses to the meaning of a word or sentence
