英语口语自动评测新方法——中国学生英语朗读自动评测系统

The Automatic Scoring System of Chinese Learners' Spoken English——A New System to Assess Oral English Proficiency

自动评测可以弥补人工评测主观性较强、费时费力等不足,但目前仍存在评测项涵盖不够全面、技术层面和语言学层面结合不够紧密等问题。为此,本研究开发了中国学生英语朗读自动评测系统,其特点体现在语音评测项、评分方式、人工专家的作用、技术模型等方面。此外,该系统基于中国英语学习者语音数据库,评测对象更具针对性。本系统的研发与不断优化对语言评测动态体系的构建及口语自动评测技术的发展具有重要的理论和实践意义。

Automatic scoring can make up for the deficiencies of artificial scoring,such as subjectivity in scoring and waste of time and energy.Nevertheless,there are still some shortcomings in current automatic scoring systems.For example,the rating items in current systems are not all-round and automatic scoring technology is not tightly linked with linguistic knowledge.A new system is therefore developed,which has advantages in rating items,scoring methods,roles of language experts,technology models,etc.In addition,this system is more targeted to Chinese English learners as it is based on the English Speech Corpus of Chinese Learners.The development and optimization of this system can promote the development of automatic assessment technology and it has great significances both in theory and practice.
