Problems solved by technology
However, in practical applications, especially for large-scale oral exams, the recording environment will inevitably be affected by factors such as the noise of the exam room and the environment, and the decline in the accuracy of speech recognition will lead to a certain proportion of abnormally scored voices in the oral evaluation process.
Obviously, this phenomenon makes it difficult for computers to automatically score in large-scale speaking tests, which limits the application scope and promotion of the speaking test system, and cannot be applied to many critical tests. Otherwise, once abnormal scores occur, marking accidents will occur.

Embodiment Construction
[0062] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0063] Aiming at the problem in the prior art that a certain percentage of abnormally scored speeches will appear in the spoken language evaluation process due to the decrease in the accuracy of speech recognition due to environmental factors, the embodiments of the present invention provide a method and system for oral language evaluation. First, the speech signal to be evaluated adopts Multiple speech recognition methods are used for recognition, and multiple speech segment sequences are obtained; then these speech segment sequences are fused to obtain valid speech segment sequences, and finally, the evaluation results are obtained by scoring the spoken language according to the valid speech segment seque...

The invention relates to the technical field of voice signal processing, and discloses a method and system for evaluating a spoken language. The method comprises the step of receiving a voice signal to be evaluated, the step of respectively obtaining voice fragments corresponding to basic voice units in the voice signal through at least two different voice recognition systems, the step of fusing the obtained voice fragments to obtain an effective voice fragment sequence corresponding to the voice signal, the step of extracting evaluating characteristics in the effective voice fragment sequence and the step of carrying out grading according to the evaluating characteristics. By means of the method and system for evaluating the spoken language, the accuracy of evaluating the spoken language can be improved, and abnormal grading can be reduced.
Description
technical field [0001] The invention relates to the technical field of speech signal processing, in particular to a spoken language evaluation method and system. Background technique [0002] As an important medium of interpersonal communication, spoken language occupies an extremely important position in real life. With the continuous development of social economy and the intensification of globalization, people have put forward higher and higher requirements for the efficiency of language learning and the objectivity, fairness and scale of language assessment. The traditional method of evaluating oral English proficiency greatly limits teachers and students in terms of teaching time and space, and there are also many hardware gaps and imbalances in terms of teachers, teaching venues, and expenditures; manual evaluation cannot avoid evaluators. Due to their own individual deviations, the uniformity of the scoring standards cannot be guaranteed, and sometimes it cannot even...
