ABSTRACT OF THE DISCLOSURE An apparatus for assisting the practice of the mother tongue or a foreign language, with a view to total assimilation thereof, comprises a standard signal generator constituted by a mobile support of sound recordings on which are previously recorded, independently of one another, blocks of sound information such as phrases or words, ex- pressed in the language having to be assimilated by a sub- ject. A reader of these blocks of information emits the standard signals. An analysis and comparison circuit is constituted by a plurality of two-input comparator and by one output stage, each of these comparators having a first input connected to the output of the standard signal generator and a second input connected to the microphone, so as to be able to ef- fect, as far as one of several parameters, such as the in- tensity, rhythm, the slope and extent of the pass band, the latency time, the precession time, the attack of the sounds, the relaxing of the sounds, etc... is concerned, an elemen- tary comparison between the standard signal emitted by the standard signal generator and the vocal signal corresponding to the sound message pronounced by the subject.
