Problems solved by technology

[0002] Foreign language teaching has a long-term and extensive demand. Due to the traditional Chinese teaching focus and teaching mode, and various types of large and medium-sized examinations do not involve oral assessment, most students have more foreign language pronunciation errors and weak oral expression.

Embodiment Construction

[0021] The specific process of a pronunciation correction method based on the visualization of pronunciation organ morphology and behavior deviation is as follows:

[0022] Step 1) corresponds to Figure 4 As shown in 001, the phonetic content and organ movements during standard pronunciation are collected, and the standard sounds are mapped to the standard pronunciation organ morphological behavior library in the form of letters, words and sentences, and the mapping function mapping() is used to map the letters, words and sentences Standard pronunciation, matched with the corresponding organ position, recorded as SP={P i , SA j};

[0023] When matching, the pronunciation parameters collected by the speech recognition module are stored in the P i ={num,cont}, num is P i The total number of cont is P i Content, the letter is saved as P 1 , the word is saved as P 2 , the sentence is saved as P 3 , SA is collected at each utterance j , with mapping (P i , SA j ) are co...

Abstract

The invention discloses a pronunciation correction method based on vocal organ form and behavior deviation visualization. The method comprises the steps: performing the foreign language learning modeling for a learner, acquiring the voice content of the learner and the organ motion corresponding to the pronunciation, and then calling a corresponding pronunciation module in a standard library according to the target foreign language selected by the learner; searching the deviations of the lip position, tongue position, tooth position, expiratory volume and jaw height of the learner and the corresponding data in the standard library by comparing the same pronunciation contents and organ movement patterns of the learner and the standard library, and visually feeding back the difference of the organ forms between the learner and the organ of the standard sound and the deviation between the two to the learner, and then updating the basic information of the learner. The method achieves therecording of the learning ability of the learner at any time to provide the learner with a coherent executable way of learning foreign languages.

Description

technical field [0001] The present invention is a pronunciation correction method based on the visualization of pronunciation organ morphology and behavior deviation. It performs foreign language learning modeling for learners, obtains the learner's voice content and the corresponding organ movements during pronunciation, and then calls out the target foreign language selected by the learner. The corresponding pronunciation module in the standard library. By comparing the same pronunciation content and organ movement patterns of the learner and the standard library, find the deviations between the learner's lip position, tongue position, tooth position, exhalation volume, and jaw height and the corresponding data in the standard library, and visualize the The difference in organ morphology between the learner and the standard pronunciation, and the deviation between the two are fed back to the learner, and then the basic information of the learner is updated, and information s...
