Intelligent children accompanying educational robot

Abstract

The invention relates to the technical field of robots, and discloses an intelligent child-accompanying educational robot for training and interacting with mouth shapes in the process of children's pronunciation. The processor of the robot of the present invention implements the following steps when executing the corresponding computer program: in the training process, synchronously collects audio and video data, and synchronizes the slicing of the face image data stream based on the audio slice, ensuring that the face image data The accuracy of stream slicing; at the same time, considering that the beginning and end of Chinese characters are the transition stages of sending and receiving respectively in the pronunciation process, the most expressive middle image data stream is selected for a series of calculations of mouth opening angles, and based on the continuous The mouth shape opening angle data sequence and the standard opening angle data sequence corresponding to the training text are compared and analyzed according to the change trend of the mouth shape angle between adjacent Chinese characters and the change trend of the mouth shape angle between adjacent sentences; to ensure the final judgment Validity and reliability of results.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an intelligent child accompanying educational robot. Background technique [0002] At present, with the continuous maturity of face recognition technology, voice and image recognition technology, video interaction and big data analysis technology, these technologies can be highly coupled with the main application scenarios of home robots to provide users with a good experience. At the same time, the advancement of technology has continuously reduced the production cost of robots, providing the possibility for scale. [0003] 2019 is regarded as the first year of children's robots, and then children's robots are known by more people and begin to develop rapidly. The unit price of child companion robots also ranges from a few hundred to tens of thousands of RMB. Children's education focuses on content and interaction. The main function of the voice dialogue of traditional childre...

Problems solved by technology

[0004] At present, speech recognition and interaction technology is very mature; however, in a wide range of children's hobbies such as speech and hosting, the mouth shape in the pronunciation process is also very important, and different Chinese characters often correspond to different mouth shapes; even the same Chinese character, due to multiple There are also differences in mouth shapes in phonetic characters, emotional colors, and tones in different usage scenarios. The current robot still lacks the function of training and interacting with the mouth shapes of children's pronunciation
