For exploiting novel use-cases, in particular sophisticated human-machine interaction, with an intraoral electronic tongue monitoring system (1) designed to be worn by a user on the upper or lower jaw and featuring a support sheet (2) bearing a number of intraoral sensors (17) arranged in an array (4) for recording tongue movement and/or tongue pressure, it is proposed that the system (1) comprises at least one extraoral sensor (6) located outside of the oral cavity (3) delimited by the teeth (19) when the system (1) is in place, in particular such that extraoral and/or intraoral and/or interlabial movements of the tongue and/or lip pressure can be recorded with the system (1) and/or such that the system (1) may be used as an input device controlled through tongue movement using a human-machine-interface provided by the system (1)
