Device for visually measuring vocal acoustic output. The invention relates to a device which makes it possible visually to measure vocal acoustic output. Vocal acoustic output is improved by a neuro-muscular action on the shaping of the oral (buccal) cavity on the basis of the display of the vocal acoustic output. The device consists of two sensors (1) and (2) which convert acoustic signals into electric signals, of two amplifiers (3) and (4) for amplifying these electric signals, of two converters (5) and (6) which convert the electrical signals of undululatory (wave) nature into continuous electric signals, of a comparator (7) which subtracts these two continuous signals, of an amplifier (8) which amplifies the continuous electric signal resulting from this subtraction, of a converter (9) which converts the electric signal from (8) into a visual signal on a magnitude scale. The present invention is particularly intended for comedians, singers, orators and speech therapists. <IMAGE>
