Example Embodiment

[0026]The embodiment of the present invention will be described below in connection with the accompanying drawings in the embodiments of the present invention.

[0027]figure 1 A flow chart of a speech-based speech-based evaluation method according to an embodiment of the present invention is shown. Such asfigure 1 As shown, the method includes:

[0028]Step 101: Set the evaluation model, the evaluation model includes encoding sub-model, align output sub-model, and identification output sub-model; encoding sub-model is used to encode the input data as a feature vector, align the output sub-model for determining the corresponding phoneme according to the feature vector. Align information, identify the output sub-model for determining the identification result of each of the phonemes in the input data according to the feature vector and phoneme alignment information.

[0029]In the embodiment of the present invention, the evaluation model mainly includes three parts, namely the encoding sub-mo...

Abstract

The invention provides a spoken language evaluation method and device based on phonemes and electronic equipment, and the method comprises the steps: setting an evaluation model; training the coding sub-model and the alignment output sub-model, and then training the recognition output sub-model under the condition of keeping the coding sub-model unchanged; inputting the target voice data into an evaluation model, determining a feature vector and phoneme alignment information of the target voice data, and determining an identification result of each phoneme in the target voice data based on the identification output sub-model; and determining an evaluation result of the target voice data according to the standard answer and the recognition result of each phoneme in the target voice data. According to the spoken language evaluation method and device based on the phonemes and the electronic equipment provided by the embodiment of the invention, the characteristics of mass data can be learned, and the phoneme alignment effect is relatively good; and a large amount of high-quality data is not needed, so that the problem of insufficient high-quality data volume in the training process is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a phoneme-based spoken language evaluation method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Speech evaluation is an important scene in the K12 (kindergarten through twelfth grade, referring to preschool education to high school education) online education scene. Online speech evaluation can effectively improve students' oral English. As an important evaluation detail of pronunciation, phoneme pronunciation evaluation plays a vital role in the accuracy of oral English scoring. Therefore, the accuracy of phoneme granule scoring not only plays an important role in the evaluation of the total score, but also plays an important role in correcting students' pronunciation details in teaching. [0003] In the current common spoken language evaluation, the evaluation of phoneme pronunciation is mostly based on the...
