Problems solved by technology

[0003] The framework of the existing automatic oral assessment methods is generally based on the assessment of reading aloud, and the machine score is obtained by evaluating the reading aloud of the tester. The selected features are mainly pronunciation and Chinese tones, and the diagnostic information is insufficient.

Abstract

The invention relates to an automatic evaluation and diagnosis method of text reading level for an oral test, which comprises the following steps: extracting voice characteristics when a tester reads the given text; training the reading characteristics, and establishing a pseudo-scoring model of artificial scoring; and in the testing process, fitting the machine scoring according to the reading characteristics and the pseudo-scoring model, and giving related diagnosis information. The tester is asked for reading the given text, thereby automatically evaluating the oral ability of the tester according to the acquired voice. The invention is characterized by using a computer to extract the voice characteristics when the tester reads the text and fitting and acquiring the machine scoring on the pseudo-scoring model, thereby achieving the purpose of evaluating the oral language ability of the tester.

Description

technical field [0001] The invention relates to the field of computer-aided language learning, in particular to a method for automatically evaluating and diagnosing the level of text reading for oral tests, which requires the tester to read a pre-set text, and then use the collected voice to test the tester's speaking ability automatic evaluation. Background technique [0002] In the past ten years, computer-aided learning technology has been widely concerned by the industry, and has made great progress, especially in the field of oral language learning, the learning method of human-computer interaction has almost been used. In this case, it is the general trend to free the oral assessment from the manual way. To do this, the computer, as a "virtual teacher", must be able to make a fair, accurate and detailed assessment of the tester's oral ability. This requires the designer to collect enough samples in a large amount of historical evaluation data to improve the evaluatio...
