Speech and language features have been proven to be useful for the detection of neurodegenerative diseases, such as Alzheimer’s disease (AD), and its prodromal stage, mild cognitive impairment (MCI). Unfortunately, high-quality speech database remains scarce, which limit its application in automatic screening and assessment of early dementia in clinical practice. To bridge this gap, the present study aimed to design a speech database of Chinese elderly with intact cognition and MCI, named “Mandarin Elderly Cognitive Speech Database” (MECSD). The database consists of 110 hours of speech recordings from 85 native speakers of Mandarin Chinese (age range = 55–85 years), including 20 participants with MCI and 65 healthy controls. Manually transcribed materials with temporal information were also included in this database. Nine tasks, involving conventional test batteries and connected speech productions, were used to obtain speech samples, producing a total of 8563 sentences and 49841 words. Details concerning the design of the database, together with our preliminary findings applying automatic speech recognition (ASR), were reported in this study. The MECSD will provide researchers with access to a large shared database that can facilitate hypothesis testing in the study of early-stage dementia.
