Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048] The invention provides a speech evaluation method and system based on speech similarity, which realizes automatic similarity scoring. Provide help for imitation learning. For language learning, imitation learning has a significant effect on language pronunciation practice. However, the existing evaluation systems are only for fair and objective evaluation of pronunciation quality, and cannot intuitively imitate pronunciation. The degree gives the evaluation results and is not directly helpful for imitation learning methods. However, the speech evaluation method and system based on speech similarity of the present invention can perceive the similarity degree of two speeches according to speech prosody characteristics, and give a similarity score, which can provide effective and intuitive feedback for learners' imitation learning, and prov...

Abstract

The invention relates to a voice evaluation method and system based on voice similarity and the method comprises the following steps: providing a training data set; using the training data set to train the dynamic time regularization algorithm and the support vector sequential regression algorithm to obtain a similarity scoring model; providing reference voice information; recording, mocking and reading the mocked voice information for the reference voice information; extracting a set of reference voice feature sequences in the reference voice information and a set of mocked voice feature sequences in the mocked voice information; and inputting the set of reference voice feature sequences in the reference voice information and the set of mocked voice feature sequences in the mocked voice information into the similarity scoring model to obtain and output the similarity scoring value between the mocked voice information and the reference voice information. On the basis of evaluating the correctness of sound making, the similarity evaluation method of the invention is added by the evaluation of the mocking of speech-making so as to assist a user to accomplish targeted mocking practice and improve their speech-making level.

Description

technical field [0001] The invention relates to the field of voice evaluation, in particular to a voice evaluation method and system based on voice similarity. Background technique [0002] Speech signal processing technology is an important branch in the field of speech processing and speech recognition, and it is also the main core technology of today's speech recognition and speech evaluation systems. With the development of science and technology, speech signal processing technology has penetrated into various fields, including language learning and automatic scoring of speech. In language learning and automatic scoring, the purpose of using speech signal processing is to integrate the latest speech technology into current teaching and Combining learning methods to establish an auxiliary language learning system or a speech intelligence scoring system. [0003] For the research on speech evaluation, most of the current evaluation methods or systems focus on how to impro...
