Speech databases for mental disorders: A systematic review

What is it about?

This review investigates into the design and development of speech corpora for mental disordered patients, which is increasingly important for medical diagnosis, treatment, and rehabilitation for mental disordered patients. The review first covers publications or resources from worldwide, and then leads to the reports from China, followed by comparison between Chinese and non-Chinese regions. The results show that most of the speech databases were recorded in Europe or the United States by audio or by video. Some were even supplemented by brain images and Event-Related Potential (ERP) statistics. The corpora were mostly developed for patients with stutter, aphasia, dementia, etc. in the domain of neurocognitive disorders, while other illnesses such as bipolar disorder, anxiety, depression, and autism were scarce in number in database development. Therefore, database development in China is much scarcer than that in some European countries, and the study not only calls for building systematic speech databases for Chinese Mandarin, but also reveals clear orientations of database application for future studies.
