The Mental State Tracker: Speech and Language Assessments on Mobile Devices
The Mental State Tracker is a mobile application currently developed for Android, iPhones and Windows phones. This mobile app is based on artificial intelligence (AI) techniques and combines a number of features: (1) The recording and analysis of speech to detect a number of mental health conditions as well as speech and language disorders (SLD). (2) The transcription of speech and the analysis of the resulting texts by various methods to determine mental health issues. (3) The analysis of transcribed speech includes the determination of suicide risk. (4) Standard questionnaires that are commonly used in clinical psychology and psychiatry are also offered and the results are compared with speech and text analysis. (5) The movement of the mobile phone (and thereby the user) is analysed to determine lack of mobility and relative social isolation. (6) DSM-5 compatibility interviews are offered to obtain more information on possible mental health conditions. Finally, (7) an explanation component is used to explain to a user "why" a certain decision was made (e.g. determination of low mood) and "how" it was made.
