Construction method of dynamic pronunciation teaching model based on 3D modeling and oral anatomy

Abstract

The invention discloses a method for constructing a dynamic pronunciation teaching model based on 3D modeling and oral anatomy, including: obtaining the physiological structure of each pronunciation organ according to the oral anatomy model in the head and neck anatomy model; Obtain a three-dimensional description of the pronunciation process of each phoneme; design the pronunciation teaching process according to the trained phonetic teaching experience model; combine the physiological structure of each pronunciation organ, the three-dimensional description of the pronunciation process of each phoneme, and the pronunciation teaching process to create a three-dimensional animation interactive teaching Model. The present invention is based on a three-dimensional oral anatomy model, combines the pronunciation attributes of each phoneme, and uses the experience of phonetic teaching, so that the sounding method of each phoneme can be visually represented by a three-dimensional animation model, so as to achieve 3D graphic and intuitive in online pronunciation teaching Teaching feedback allows learners to more accurately capture the changes in key pronunciation parts, improving the teaching effect.

Description

technical field [0001] The invention relates to the technical field of pronunciation teaching, in particular to a method for constructing a dynamic pronunciation teaching model based on 3D modeling and oral anatomy. Background technique [0002] Against the background of the global outbreak of the COVID-19 virus, artificial intelligence is developing rapidly in the field of education, and online teaching has gradually become a learning method that everyone is willing to accept. The new teaching method also poses new challenges to the traditional classroom teaching mode. Pronunciation teaching in traditional classrooms mainly relies on the teacher's demonstration through language, teaching aids or body, so that students can comprehend specific actions by themselves. This teaching method is highly ambiguous, and it is difficult to meet the needs of online teaching and computer-aided pronunciation teaching feedback. [0003] In terms of pronunciation teaching, in the absence o...

Problems solved by technology

However, the cost of data collection and analysis in this way is high and difficult, mainly manifested in the fact that the sensor needs to be attached to the speaker’s vocal organs at a specific position, which will bring strong discomfort to the speaker and affect the naturalness of pronunciation; Sensor electrodes fall off, which may cause data collection failure or inaccurate collection; the number of sensor electrodes is limited, and data modeling may face problems such as data sparseness

Moreover, the pronunciation data obtained in this way is difficult to analyze, and it is difficult to meet the flexible needs of pronunciation teaching
