Query: Speech and the n-Back task as a lens into depression. How combining both
  may allow us to isolate different core symptoms of depression   Embedded in any speech signal is a rich combination of cognitive,
neuromuscular and physiological information. This richness makes speech a
powerful signal in relation to a range of different health conditions,
including major depressive disorders (MDD). One pivotal issue in
speech-depression research is the assumption that depressive severity is the
dominant measurable effect. However, given the heterogeneous clinical profile
of MDD, it may actually be the case that speech alterations are more strongly
associated with subsets of key depression symptoms. This paper presents strong
evidence in support of this argument. First, we present a novel large,
cross-sectional, multi-modal dataset collected at Thymia. We then present a set
of machine learning experiments that demonstrate that combining speech with
features from an n-Back working memory assessment improves classifier
performance when predicting the popular eight-item Patient Health Questionnaire
depression scale (PHQ-8). Finally, we present a set of experiments that
highlight the association between different speech and n-Back markers at the
PHQ-8 item level. Specifically, we observe that somatic and psychomotor
symptoms are more strongly associated with n-Back performance scores, whilst
the other items: anhedonia, depressed mood, change in appetite, feelings of
worthlessness and trouble concentrating are more strongly associated with
speech changes.
