Voice evaluation method and device

Abstract

The invention is suitable for the field of computer evaluation, and provides a voice evaluation method and device. The method comprises the steps: obtaining a to-be-evaluated audio; extracting a characteristic quantity of the audio; generating a score corresponding to the characteristic quantity according to a preset scoring standard and the characteristic quantity of the audio; generating and displaying a radar map corresponding to the score according to the score of the characteristic quantity, so as to enable an evaluator to score the to-be-evaluated voice according to the radar map. According to the invention, the method and device employs a mode of man-machine combination, enables the evaluator to be able to accurately give a score through generating the visual radar map, and reduces the scoring fault of the voice evaluation.

Description

technical field [0001] The invention belongs to the field of computer evaluation, in particular to a method and device for voice evaluation. Background technique [0002] With the deepening of opening to the outside world and internationalization, the demand for foreign language oral teaching and evaluation is increasing day by day, and the oral English test has become a compulsory item for the high school entrance examination and college entrance examination in many regions. Traditional manual grading requires a lot of manpower and material resources, and the reliability of grading is affected by subjective factors such as the level and physiological state of the grading person, and its objective fairness cannot be guaranteed. In recent years, with the advancement of computational speech information processing technology, automatic spoken language evaluation technology based on computer automatic speech recognition has been widely used. The current mainstream computer auto...

Problems solved by technology

Although the statistical model can reflect the overall trend of the data, the current speech recognition technology is not yet 100% accurate, coupled with the statistical errors in the fitting process, the automatic scoring of the machine cannot be completely consistent with the expert scoring. unanimous

In some very important exams, such as the senior high school entrance examination and the college entrance examination, even if the error is within 10%, it will cause doubts from candidates, parents, teachers and all walks of life, making the popularization of computer automatic marking technology encounter great resistance
