[0002] English is a West Germanic language and the most widely spoken language in the world. Its grammar, writing, and spelling are completely different from those of Chinese. When learning English, speaking English is an important step in learning English and requires regular practice to achieve standard pronunciation.

[0003] Existing spoken English learning devices mainly have the following shortcomings:

[0004] 1. Long-term use may affect posture and vision. Since most English speaking learning devices are placed on the desktop for learning, users need to lower their heads to view the content above. Long-term use will affect posture and vision.

[0005] 2. It is impossible to teach synchronously with the textbooks and homework content. Since textbooks are updated very quickly, it is difficult for online courses to be updated synchronously with the textbooks. Since each school has no unified restrictions on homework, it is even more difficult to synchronize the content. As a result, if users want to use current English speaking learning devices for tutoring, they often need to follow the online courses from the beginning. Summary of the Invention

[0054] As a specific embodiment of the present invention, the third servo 3005 is located at the bottom of the turntable 3001, the second servo 3004 is located on one side of the second articulated seat 3002, the fixed end of the third servo 3005 is fixedly connected to the turntable 3001, the output shaft of the third servo 3005 passes through the inner wall of the turntable 3001 and is transmission-connected to the second articulated seat 3002, the fixed end of the second servo 3004 is fixedly connected to the outer wall of the second articulated seat 3002, the output shaft of the second servo 3004 passes through the outer wall of the second articulated seat 3002 and is transmission-connected to the second camera 3003.

[0055] During operation, the output shaft of the third servo 3005 passes through the inner wall of the turntable 3001 and is connected to the second articulated seat 3002 for transmission, so that the rotation of the third servo 3005 can drive the second articulated seat 3002 to rotate, and the output shaft of the second servo 3004 passes through the outer wall of the second articulated seat 3002 and is connected to the second camera 3003 for transmission, so that the rotation of the second servo 3004 drives the second camera 3003 to rotate.

[0056] The specific workflow is as follows:

[0057] First, place the courseware or homework that needs to be assisted in learning between the first clamping block 2016 and the second clamping block 2020. The elastic force of the spring 2018 can make the second clamping block 2020 clamp the courseware or homework. Different control gestures are preset in the gesture recognition system. The intelligent English teaching system is entered through gestures. The intelligent English teaching system will automatically start the third servo 3005 through the control chip. The third servo 3005 drives the second articulated seat 3002 to rotate, so that the second camera 3003 is aimed at the courseware or homework that needs to be assisted in learning. Then the intelligent English teaching system will start the second servo 3004 through the control chip. The second servo 3004 drives the second camera 3003 to rotate, controlling the second camera 3003 to rotate. The pitch angle of the camera 3003 makes it easy to position the second camera 3003 on specific courseware and homework content. The captured content will be displayed on the display 1001 for the user to watch. The user can use the intelligent English teaching system to read the text, translate unknown words, or associate short sentences based on unknown words through gestures. Since the display height is flush with the correct sitting posture of an average user, it can protect the user's cervical spine. Since the user maintains a posture for a long time, the shoulder muscles will become stiff and tense, affecting the body shape. Maintaining a certain viewing distance for a long time will cause the lens to reduce its ability to adjust the focal length, thus causing myopia. After the user has used it for a period of time, the control chip will automatically start the electric telescopic rod 1009. The electric telescopic rod 1009 drives the second connecting rod 1007 to swing. Since the first connecting rod 1006 and the second connecting rod 1007 are respectively hinged to the first hinge seat 1005, and the first connecting rod 1006 and the second connecting rod 1007 are parallel to each other, the swing of the second connecting rod 1007 drives the display 1001 to swing. The display 1001 will rise or fall when it swings. The display 1001 moves closer to or away from the user while rising and falling. At the same time, the voice prompts the user to follow the movement of the screen, thereby activating the user's neck and changing the visual distance. The display 1001 will always remain in a vertical state. When it is necessary to turn the page, the control chip can start the first micro stepping motor 2007 and the second micro stepping motor 2008 through gestures. When the first micro-stepping motor 2007 and the second micro-stepping motor 2008 drive the first slider 2005 and the second slider 2006 to move synchronously in one direction respectively, the third connecting rod 2009 and the fourth connecting rod 2010 will follow the first slider 2005 and the second slider 2006 to move synchronously without swinging, so that the fourth connecting rod 2010 drives the fixed block 2023, the suction cup 2017 and the vacuum pump 2014 to move through the fifth connecting rod 2011. When only the first micro-stepping motor 2007 is started, the first micro-stepping motor 2007 drives the second slider 2006 to move to one side. Since the end of the third connecting rod 2009 away from the second slider 2006 is hinged to the fourth connecting rod 2010 through the rotating shaft,As a result, the second slider 2006 drives the fourth connecting rod 2010 to swing in the direction of movement through the third connecting rod 2009. When only the second micro-stepping motor 2008 is started, the second micro-stepping motor 2008 drives the first slider 2005 to move, and the first slider 2005 drives the fourth connecting rod 2010 to swing in the direction opposite to the moving direction of the first slider 2005. When the first micro-stepping motor 2007 and the second micro-stepping motor 2008 are started respectively, and the first slider 2005 and the second slider 2006 are moved away from each other, the fourth connecting rod 2010 will accelerate to swing in the direction of the second slider 2006, so that the movement and swing of the suction cup 2017 can be freely controlled by controlling the first micro-stepping motor 2007 and the second micro-stepping motor 2008. When the suction cup 2017 moves to the courseware or homework required When the page is turned, the vacuum pump 2014 is started. When the vacuum pump 2014 is working, the suction cup 2017 generates negative pressure, which absorbs the page of the courseware or homework. Then, by controlling the first micro-stepping motor 2007 and the second micro-stepping motor 2008, the suction cup 2017 is swung in the direction in which the page needs to be turned. The suction cup 2017 drives the page of the courseware or homework to swing to realize page turning. When it is necessary to turn the page back, the control chip will start the first servo 2013. The first servo 2013 drives the fixed block 2023 to turn 180 degrees. The fixed block 2023 drives the suction cup 2017 to turn 180 degrees. Then, the second slider 2006 can move to the left side of the first slider 2005, causing the fourth connecting rod 2010 to swing to the left. Then, the first micro-stepping motor 2007 and the second micro-stepping motor 2008 are controlled to turn the page.
