The Mental State Tracker: A Mobile phone based approach
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.

The next video describes speech analysis for anger in MatLab (for development purposes). A German language voice is used in this video.

Kriton Speech
Kriton Speech is a speech-only knowledge acquisition system. Voice user interfaces (VUI) allow a user to perform other tasks while s/he is interviewed by the knowledge acquisition system. Kriton Speech takes the VUI concept to the extreme: there are start and stop buttons, everything else is done by speech.
The knowledge acquisition tool Kriton Speech is designed for users unfamiliar with artificial intelligence (AI) techniques as well as well-trained knowledge engineers. Kriton Speech is a general purpose knowledge acquisition tool incorporating several interview techniques.
