EWA-DB – Early Warning of Alzheimer speech database

EWA-DB is a speech database that contains data from 3 clinical groups: Alzheimer's disease, Parkinson's disease, mild cognitive impairment, and a control group of healthy subjects. Speech samples of each clinical group were obtained using the EWA smartphone application, which contains 4 different language tasks: sustained vowel phonation, diadochokinesis, object and action naming (30 objects and 30 actions), picture description (two single pictures and three complex pictures). The total number of speakers in the database is 1649. Of these, there are 87 people with Alzheimer's disease, 175 people with Parkinson's disease, 62 people with mild cognitive impairment, 2 people with a mixed diagnosis of Alzheimer's + Parkinson's disease and 1323 healthy controls. For speakers who provided written consent (total number of 1003 speakers), we publish audio recordings in WAV format. We are also attaching a JSON file with ASR transcription, if available manual annotation (available for 965 speakers) and additional information about the speaker. For speakers who did not give their consent to publish the recording, only the JSON file is provided. ASR transcription is provided for all 1649 speakers. All 1649 speakers gave their consent to the provider to process their audio recordings. Therefore, it is possible for third party researchers to carry out their experiments also on the unpublished audio recordings through cooperation with the provider.

EWA-DB是一款语音数据库，涵盖4组受试者的语音数据：阿尔茨海默病（Alzheimer's disease）患者、帕金森病（Parkinson's disease）患者、轻度认知障碍（mild cognitive impairment）患者，以及健康对照组受试者。所有临床组的语音样本均通过EWA智能手机应用程序采集，该应用内置4种语言任务：持续元音发声、轮替运动言语（diadochokinesis）、物体与动作命名任务（包含30个物体及30个动作条目）、图片描述任务（包含2张单幅图片与3张复杂图片）。该数据库总计纳入1649名受试者：其中阿尔茨海默病患者87例，帕金森病患者175例，轻度认知障碍患者62例，阿尔茨海默病合并帕金森病混合诊断患者2例，健康对照受试者1323例。针对签署书面知情同意的1003名受试者，研究团队公开了其WAV格式的语音录音；若存在人工标注结果（适用于965名受试者），还将同步附带包含自动语音识别（ASR）转录文本及受试者额外信息的JSON文件。对于未同意公开录音的受试者，仅提供其对应的JSON文件。所有1649名受试者的ASR转录结果均已提供。全体受试者均同意数据提供方对其语音录音进行处理，因此第三方研究人员可通过与数据提供方合作，基于未公开的录音开展相关实验研究。
