Spoken language formative teaching method and system based on multi-parameter analysis

Abstract

The invention discloses a spoken language formative teaching method and system based on multi-parameter analysis. The method comprises the following steps: obtaining spoken language test voice, and preprocessing the spoken language test voice; extracting feature parameters from the preprocessed spoken language test voice; performing multi-parameter evaluation on the feature parameters to obtain a multi-parameter evaluation result; performing graded processing on the multi-parameter evaluation result to obtain comprehensive pronunciation guidance; and according to the comprehensive pronunciation guidance and preset rules, forming personal learning information, class learning information and paragraph learning information. The spoken language formative teaching method and system based on the multi-parameter analysis, provided by the embodiments of the invention, test spoken language through multiple parameters, process a test result and can satisfy the learning demand of students and the teaching demand of teachers.

Description

technical field [0001] The invention relates to the technical field of speech recognition and evaluation, in particular to a method and system for oral formative teaching based on multi-parameter analysis. Background technique [0002] The research on computer-aided teaching system is a current hot issue. The "College English Curriculum Teaching Requirements" formulated by the Ministry of Education pointed out that "the new teaching mode should be supported by modern information technology, especially network technology, and make full use of modern information technology. At the same time, it is necessary to reasonably inherit the excellent parts of the traditional teaching model and give full play to the advantages of traditional classroom teaching. There should be corresponding face-to-face tutoring hours to ensure the effect of learning.” Formative assessment (formative assessment), also known as process assessment, is in It is an instant, dynamic, and repeated evaluation...

Problems solved by technology

[0003] The current teaching evaluation system does not make good use of formative evaluation. "Through certain teaching methods, students' learning status is known, and teachers and students make corresponding adjustments to teaching methods or learning methods on the basis of careful analysis of this learning status." Most of the theories of "adjustment" simply reflect the learning status of students to individual teachers, and do not give full play to students' subjective initiative through feedback to students

In addition, in presenting the students' learning status to teachers, most of the existing systems only conduct simple descriptive statistics on the test scores, so the statistical results can only reflect the general situation of the test group, and cannot go deep into specific students. Individual and test-question-by-test analysis does not reflect trends in a student's learning level over a period of time
