摘　　要：为了克服传统Cookie Theft测验费时费力、评测结果受主观影响等不足,提出了一种数字化测评方法.首先,将Cookie Theft测验转化成总分为28分的数字化量表;接着,分析对比了脑小血管病组和健康组分别在无提示语和有提示语条件下的表现差异情况;最后,综合语音相关特征及信息量相关特征,利用随机森林方法建立了脑小血管病智能诊断模型.实验结果显示,综合使用测试过程中记录的语音相关特征和信息量相关特征,脑小血管病智能诊断模型的识别准确率可达82.4%.In order to overcome the shortcomings of the traditional Cookie Theft test,such as time-consuming and labor-intensive test,and subjective influence on the evaluation results,a new digital assessment method was proposed.Firstly,the Cookie Theft test was convert into a digital scale with a total score of 28.Secondly,the performance differences between the cerebral small vessel disease group and the healthy group under the condition of silent and prompt words were analyzed and compared.Finally,based on the speech-related features and information-related features,an intelligent diagnosis model of cerebral small vessel disease was established by using random forest algorithm.The experimental results show that using the voice-related features and information-related features recorded during the test process,the recognition accuracy of the intelligent diagnosis model for cerebral small vessel disease can reach 82.4%.
