Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] The complete process of this clear semi-open oral test method consists of two stages:

[0032] Model training phase: the training part includes training the acoustic model, the prediction model from the pronunciation evaluation feature to the pronunciation score, the prediction model from the fluency feature to the fluency score, the prediction model from the prosodic feature to the prosody score, and the prediction model from the four module scores to the overall score .

[0033] The method for automatic scoring of semi-open test questions in spoken English includes a model training part, and the model training process includes the following steps:

[0034] (A) Construct the voice database aimed at the characteri...

Abstract

The invention provides a testing method and system of semi-opened spoken language examination questions, for realizing fully-automatic grading for the semi-opened spoken language examination questions through starting with a key content detection and text independence evaluation technology and leaping over dependence on voice recognition. In the invention, the evaluation of spoken language voice includes four parts, i.e., content, pronunciation, fluency and rhythm, and therefore, the foundation is laid for the evaluation work of spoken language.

Description

technical field [0001] The present invention relates to the fields of speech recognition, speech signal processing, computer-aided language learning, etc., and in particular to a method of using a computer to record semi-open spoken language test questions for test personnel, and then process them with a computer to obtain semi-open test test questions for test personnel. Method and system for overall scoring. Background technique [0002] Voice is one of the main ways of information exchange and dissemination. As an important medium of interpersonal communication, oral language learning occupies an extremely important position in real life. Standard speech is the basis of speaking and listening, which can enhance the reliability of daily communication and improve the fluency of communication. 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 lear...
