基于WEB的普通话自动测评系统的研究

下载后可任意编辑摘 要本文主要是基于 WEB 的普通话自动测评系统的讨论。本系统可以有效地避开人工测试中的弊端，也可以省去大量的人力和资源。通过大量的讨论发现：开发此系统可以通过采集大量的普通话语音信号，建立一个语音库，然后分析其信号波形，通过比对与匹配来实现语音识别和自动测评。但是，由于条件有限，本课题没有实行这种方法。本系统采纳了微软提供的语音程序开发组件Speech SDK 5.1，即通过调用 SDK 中相关的语音应用程序接口(SAPI)来实现普通话考试的自动测评。本论文的主要内容有普通话测试的相关题库的建立、普通话语音的采集与分析、对采集的语音与标准答案进行比对算法讨论，以及计算机自动阅卷评分的讨论。实验测试结果表明：本系统能够实现对单字、双字等项目的测试并评分，取得了预期的效果，可以为今后的进一步讨论提供较好的参考。关键词：普通话，自动测评，语音识别，SPEECH SDKI下载后可任意编辑ABSTRACTThis paper studies the Mandarin automatic test system based on Web. The system will effectively avoid the shortage of manual test, also save a huge amount of manpower and resources. Through lots of study, I know that this system can be developed by collecting a lot of Mandarin speech signal and establishing a speech library, then analyzing the signal waveform, and through matching to realize automatic speech recognition and test. However, due to limited conditions, the subjects did not take this method. The system uses Speech SDK 5.1 , a development component for the Speech procedures provided by the Microsoft Corporation. It means that we can realize the Mandarin automatic test by calling Speech Application Programming Interface(SAPI) associated with SDK. This paper mainly includes the establishment of Mandarin test papers’ library, the collection and analysis of the Mandarin speech, the research on the algorithm of matching between the acquired speech and the standard answer ,and on the automatic accounting scores by computer.
