Description

Technical Field

[0001] The invention relates to a foreign language teaching device and a use method, in particular to a foreign language slang teaching device with a fuzzy recognition function, belonging to the technical field of foreign language teaching tools. Background Art

[0002] Slang refers to informal and more colloquial sentences among the people. It is a popular, catchy and local-flavored phrase summed up by the people in their daily lives. It has a strong regional flavor and is more lifelike. English slang is a commonly used language in English, usually used in informal occasions. Head-mounted oral teaching headphones are usually used to train students' oral language. During the training process, the students' oral training voice is synchronously transmitted to the speech recognition learning host for oral correction, and the recognition information is displayed on the display screen.

[0003] Chinese patent announcement number CN206907254U discloses an English oral teaching device, including a display board frame, a display board, a display screen frame and a base. At least one permanent magnet is arranged in the display board frame, and the top of the permanent magnet is flush with the surface of the display board frame; a metal positioning block corresponding to the permanent magnet is arranged on the back of the display board; a display screen frame is arranged on the top of the display board frame, and a groove for placing the display screen is arranged in the middle of the display screen frame, and the base is perpendicular to the display board frame and fixedly connected to the bottom end of the display board frame.

[0004] However, the inventor of the above device believes that there are certain defects. When the above device is used to pronounce English, the deviation of the mouth shape cannot be clearly seen, and the display screen is fixed, which is not convenient for students to adjust to a convenient observation and learning angle. Therefore, the present invention provides a foreign language slang teaching device with a fuzzy recognition function.

[0005] In addition, conventional foreign language slang teaching devices lack the comparison between one's own lip shape and the correct lip shape, and conventional people are in a moving state, so it is difficult to keep themselves still. As a result, even if the correct lip shape is generated, the matching of the correct lip shape generation data with the current person's facial data may be affected by the parameters of the device such as the degree of inclination and the rate of change of the angle, as well as the dynamics of human behavior. In addition, the teaching equipment has high requirements on precision and should avoid the influence of factors such as dust, and avoid the influence of dust on long-term use. Summary of the invention

[0044] (3) The voice database information of the learner is stored in advance in the foreign language slang teaching device system, and the voice information of the current learner is identified by voice fuzzy recognition technology and matched with the voice information of the user in the data. If the data in the database is successfully matched, the foreign language slang teaching device system successfully authorizes the user, and the authorized user can use the foreign language slang teaching device;

[0045] (4) After successful authorization, the camera uses facial recognition to control the adjustment mechanism to adjust the angle so that the learner's line of sight is close to perpendicular to the screen, making it easier for the learner to see whether his or her mouth shape is correct through the screen; at the same time, the surface of the mounting seat can be cleaned synchronously while the angle is adjusted;

[0046] (5) The learner pulls out the storage box (12) and conveniently takes out the earphones through the buffering and vibration absorbing structure.

[0047] Furthermore, step (3) also includes collecting a large number of slang lip shape image information, performing machine learning and / or deep learning, and overlaying the correct lip shape onto the learner's current image information through augmented reality according to the slang the learner currently wants to learn, to guide the learner to learn the correct lip shape.

[0048] Furthermore, step (3) also includes evaluating the learner's pronunciation information and the correct pronunciation, and giving a deviation; setting a facial angle change threshold, if the facial angle calculated by the camera changes slightly and does not exceed the facial angle change threshold, the adjustment mechanism is not activated. At this time, the system predicts the correct mouth shape image data based on the current position data of the foreign language slang teaching device system, the facial angle change speed and the facial recognition data, and covers the learner's current image information to guide learning the correct mouth shape; if the facial angle calculated by the camera changes and exceeds the facial angle change threshold, the adjustment mechanism is activated to make the learner's eye line nearly perpendicular to the screen. At this time, the system predicts the correct mouth shape image data based on the current position data of the foreign language slang teaching device system, the facial angle change speed, the angle change speed data and the facial recognition data, and covers the learner's current image information to guide learning the correct mouth shape.
