Negative symptoms in schizophrenia are associated with significant
burden and functional impairment, especially speech
production. There are no robust
treatments for negative symptoms and one obstacle surrounding
its research is the lack of an objective measure. To this
end, we explore non-verbal speech cues as objective measures.
Specifically, we extract these cues while schizophrenic
patients are interviewed by psychologists. Our results suggest a
strong correlation between certain measures of the two rating
sets.
