Abstract

This system allows to evaluate the pronunciation of a word or a sentence, compared with a "reference" pronunciation. It is comprised of an input microphone (1) for the user and an input microphone or recording (2) for the "reference". The two sound signals transformed into electric signals are amplified at "3", digitized and analysed at (4), stored at (5), and compared at (10). They are audible at (9). The comparison result evaluated according to a preselected level (11) is announced at (9) and displayed at (12). The user will be able to repeat till he reaches a maximum of resemblance with the "reference" pronunciation. This system allows, by confrontation with the "reference", to measure the performance of the user and to efficiently improve his pronunciation in any language.

Description

L'invention se rapporte à un système électronique permettant d'analyser et d'évaluer la prononciation d'un mot ou d'une phrase d'une personne, en la comparant à une prononciation "référence" à introduire. I1 permet ainsi d'améliorer la prononciation et la diction de cette personne dans une langue quelconque. The invention relates to an electronic system making it possible to analyze and evaluate the pronunciation of a word or a sentence of a person, by comparing it with a “reference” pronunciation to be introduced. It thus makes it possible to improve the pronunciation and the diction of this person in any language.

Ce système offre un moyen très efficace et agréable pour apprendre des langues et bien les parler. This system offers a very effective and pleasant way to learn languages and speak them well.

Divers procédés existent actuellement permettant une certaine compréhension de la parole par le moyen d'une comparaison avec un certain vocabulaire préalablement enregistré. Ils servent en général à "comprendre des messages parlés" pour l'exécution des commandes dans les ensembles automatisés. Various methods currently exist allowing a certain understanding of speech by means of a comparison with a certain vocabulary previously recorded. They are generally used to "understand spoken messages" for the execution of commands in automated assemblies.

L'invention présentée a un but essentiellement éducatif, mais pourrait avoir d'autres applications, notamment industrielles. Elle permet, par un suivi électronique intégré, d'améliorer la prononciation et d'atteindre le maximum de ressemblance avec une référence déterminée. The invention presented has an essentially educational purpose, but could have other applications, in particular industrial. It allows, through an integrated electronic tracking, to improve the pronunciation and to reach the maximum resemblance with a determined reference.

L'invention sera mieux comprise par la description qui suit d'un mode de réalisation donné à titre d'exemple non limitatif. The invention will be better understood from the following description of an embodiment given by way of nonlimiting example.

Le système selon l'invention comprend une entrée microphone ou enregistrement à vitesse variable (2) pour la prononciation "référence", et une entrée microphone (1) pour la prononciation de l'utilisateur à analyser. The system according to the invention comprises a microphone input or variable speed recording (2) for the pronunciation "reference", and a microphone input (1) for the pronunciation of the user to be analyzed.

Les deux signaux correspondant aux entrées (1) et (2) ont un parcours identique dans le système selon la figure 2, et les deux prononciations sont audibles successivement par le haut-parleur (9) à travers le synthétiseur (7) et l'amplificateur (8). La sortie par le haut-parleur est commandée alternativement par les deux signaux entrant dans le système.The two signals corresponding to the inputs (1) and (2) have an identical route in the system according to FIG. 2, and the two pronunciations are heard successively by the loudspeaker (9) through the synthesizer (7) and the amplifier (8). The output through the loudspeaker is controlled alternately by the two signals entering the system.

Après amplification avec contrôle automatique de gain (3), les deux signaux analogiques sont transformés en signaux numériques et traités dans le circuit analyseur (4) pour en déterminer les différentes caractéristiques phonétiques. Ils sont ensuite enregistrés dans une mémoire (5) et comparés entre eux en (10). La comparaison peut se faire au choix par "mot" ou par "phrase entière" suivant le sélecteur (6). Le résultat de la comparaison est déterminé par le niveau de connaissance choisi au départ par les boutons-poussoirs à lampe témoin (11). After amplification with automatic gain control (3), the two analog signals are transformed into digital signals and processed in the analyzer circuit (4) to determine the different phonetic characteristics. They are then recorded in a memory (5) and compared with each other in (10). The comparison can be made either by "word" or by "whole sentence" according to the selector (6). The result of the comparison is determined by the level of knowledge initially chosen by the indicator light pushbuttons (11).

Le système offre le choix entre plusieurs niveaux de connaissance: "fort", "moyen", et "débutant" par exemple.  The system offers the choice between several levels of knowledge: "strong", "medium", and "beginner" for example.

Le résultat est exprimé selon un ordre d'évaluation : A (très bien),
B (bien), C (moyen), D (passable), E (répéter) par exemple; il est annoncé par le haut-parleur (9) et signalé par un voyant lumineux (12). Plus le niveau de connaissance choisi est élevé, plus l'évaluation du système est sévère. Ces niveaux et ces évaluations peuvent être modifiés selon le modèle d'appareil désiré.The result is expressed according to an evaluation order: A (very good),
B (good), C (average), D (fair), E (repeat) for example; it is announced by the loudspeaker (9) and indicated by an indicator light (12). The higher the level of knowledge chosen, the more severe the evaluation of the system. These levels and ratings can be changed depending on the desired device model.

Un circuit de commande (13) fera avancer l'enregistrement "référence" automatiquement si le résultat de la comparaison est A (très bien), B (bien),
C (moyen) ou D (passable).A control circuit (13) will automatically advance the "reference" record if the result of the comparison is A (very good), B (good),
C (medium) or D (fair).

Si ce résultat est E (répéter) ou si la commande de répétition manuelle (14) a été actionnée, le circuit de commande (13) enverra un message "répéter" qui sera affiché dans la fenêtre (15) et audible dans le hautparleur (9); il fera ensuite repasser la prononciation "référence" dans le haut-parleur, et l'utilisateur répétera le mot ou la phrase jusqu'à l'obtention d'un meilleur résultat. Pendant tout ce temps l'entrée (2) est bloquée et la partie "référence" reste en mémoire tant qu'il n'y a pas d'ordre de continuer. L'audition est aussi possible par l'écouteur (16). If this result is E (repeat) or if the manual repeat command (14) has been actuated, the control circuit (13) will send a "repeat" message which will be displayed in the window (15) and audible in the loudspeaker ( 9); it will then play back the pronunciation "reference" in the loudspeaker, and the user will repeat the word or phrase until a better result is obtained. During all this time the entry (2) is blocked and the "reference" part remains in memory as long as there is no order to continue. Hearing is also possible through the earpiece (16).

I1 est néanmoins possible d'annuler manuellement cette répétition et de faire avancer l'entrée (2). Cette annulation se fait par le sélecteur (14) à trois fonctions: répétition manuelle - fonctionnement normal - annulation répétition automatique. It is nevertheless possible to manually cancel this repetition and advance the entry (2). This cancellation is made by the selector (14) with three functions: manual repetition - normal operation - automatic repetition cancellation.

Les figures 1 et 2 sont respectivement une configuration et un schéma de fonctionnement, et la figure 3 est un diagramme fonctionnel du circuit de commande (13); elles sont données à titre indicatif et illustrent le système selon l'invention. Figures 1 and 2 are respectively a configuration and an operating diagram, and Figure 3 is a functional diagram of the control circuit (13); they are given for information only and illustrate the system according to the invention.

Bien entendu la présente invention ne se limite pas au mode de réalisation décrit et représenté, mais s'étend au contraire à toutes variantes de fonctionnement, de forme, de dimension et d'application.  Of course, the present invention is not limited to the embodiment described and shown, but on the contrary extends to all variants of operation, shape, size and application.
