英文发音中错误语音自动识别系统设计Design of error speech automatic recognition system for English pronunciation
王兴刚
摘要(Abstract)：
传统的英文发音识别系统对于学习者的错误发音不能及时进行反馈与纠正,存在误导学习者以及学习者英文水平提高缓慢的弊端。在此设计新的英文发音错误语音自动识别系统,其由语音录制模块、语音播放模块、英语发音评分模块和发音共振峰图像显示模块构成,给出评分模块的发音评分流程,实现英文发音的有效评分以及评分的存储,系统通过发音共振峰图形显示模块,清晰地表达出学习者发音与标准发音的不同之处,纠正其错误读音。通过英语音素检错程序使用独立阈值的方式来提高错误读音的检测性能,对不同音素用独立阈值进行衡量,使得英语发音中的错误语音自动识别结果更加科学化、精准化。实验结果表明,所设计的系统具有较高的错误语音自动识别能力。
