摘　　要：目的研制一款适用于中国老年人的智能语音交互认知功能评估工具,用于早期筛查轻度认知障碍。方法利用微信开发者工具、语音识别技术、机器学习模型,研制一款语音交互的智能认知评估工具(SCS)。招募50~80岁受试者,采用SCS小程序和蒙特利尔认知评估基础版(Montreal Cognitive Assessment Basic,MoCA-B)进行评估,对SCS小程序认知评估的准确性作初步验证。结果SCS支持用户通过语音答题自主完成命名、即刻和延迟回忆、符号数字转换等认知任务,结合答题表现和语音的数字生物标志物对记忆、注意和语言等认知功能进行评估,并即刻生成报告,全程仅7 min。207名受试者的平均SCS分数为(86.80±15.53)分,与MoCA-B有良好的相关性(Pearson’s r=0.615,P<0.001)。结论SCS小程序适用于对中国老年人进行认知功能评估,较传统工具高效便利,值得推广用于社区筛查、远程评估和居家自测。Objective To research and develop an intelligent speech interaction cognitive screening tool for screening mild cognitive impairment in Chinese older adults.Methods By using WeChat developer tools,speech recognition technology and machine learning model,an intelligent Shanghai Cognitive Screening(SCS)tool for speech interaction was developed.Participants aged 50 to 80 years were recruited and evaluated using the SCS mini-program and Montreal Cognitive Assessment basic(MoCA-B)to preliminatively verify the accuracy of the SCS mini-program cognitive assessment.Results The SCS allowed users to independently perform cognitive tasks such as naming,immediate and delayed memory,and symbol digit modalities test,etc.Combined with answer performance and digital biomarkers of speech,cognitive functions such as memory,attention and language were evaluated,and assessment reports were generated immediately.The whole process was only 7 min.The average SCS score of 207 participants was(86.8±15.53)scores,which had a good correlation with MoCA-B(Pearson’s r=0.615,P<0.001).Conclusion The SCS miniprogram is suitable for assessing cognitive function in Chinese older adults,and is more efficient and convenient than traditional tools.It is worth promoting for community screening,remote assessment,and home self-testing.
