Abstract

The invention provides a spoken language pronunciation evaluation method and system for a minority language and a storage medium. The method comprises the steps of obtaining a target text, a pronunciation dictionary and a reading audio made by a user according to the target text; generating a phoneme decoding result and a phoneme alignment result by using a speech recognition model; performing sound beat analysis on the target text based on the language pronunciation characteristics to obtain a sound beat analysis result; performing pitch analysis on target voice data to obtain a pitch analysis result; obtaining an accuracy score, an intonation score and a tone score of a read audio, taking the intonation score as a second pronunciation evaluation result, and taking the tone score as a third pronunciation evaluation result; and fusing the accuracy score, the intonation score and the tone score to obtain a total score of sentence pronunciation. According to the method, voice is calculated and analyzed from multiple different dimensions such as accuracy, integrity, fluency, sentence segmentation, tone and intonation according to the pronunciation characteristics of the minority language to obtain an evaluation result.

Description

technical field [0001] The present invention relates to the technical field of speech recognition and evaluation, in particular, to a pronunciation evaluation method, system and storage medium for spoken language in minority languages. Background technique [0002] Most of the common oral pronunciation evaluation systems are designed for the widely used English language, and are used to judge the accuracy of pronunciation. The quality evaluation result of the spoken speech is obtained by comparing the characteristic parameters of the test speech with those of the standard speech. The above methods cannot perform quality evaluation at the granularity of small pronunciation units. The evaluation results will also be affected by the speaker's personal pronunciation characteristics. For example, if the speaker and the standard pronunciation reader are of the same gender and age, the score will be higher. In addition, since the above-mentioned system is designed for the pronunc...
