Systems and methods for mental health assessment
First Claim
1. A method for identifying whether a subject is at risk of having a mental or physiological condition, comprising:
- (a) obtaining data from said subject, said data comprising speech data and optionally associated visual data;
(b) processing said data using a plurality of machine learning models comprising a natural language processing (NLP) model and an acoustic model to generate an NLP output and an acoustic output, wherein said plurality of machine learning models comprises a neural network trained on labeled speech data collected from one or more other subjects, wherein said labeled speech data for each of said one or more other subjects is labeled as (i) having, to some level, said mental or physiological condition or (ii) not having said mental or physiological condition;
(c) fusing said NLP output and said acoustic output by (1) applying weights to said NLP output and said acoustic output to generate weighted outputs and (2) generating a composite output from said weighted outputs, wherein said NLP output and said acoustic output each comprise a plurality of outputs corresponding to a plurality of time segments of said speech data, and wherein said weights in (1) are temporally-based; and
(d) outputting an electronic report identifying whether said subject is at risk of having said mental or physiological condition, based at least on said composite output, which risk is quantified in a form of a score having a confidence level provided in said report.

Abstract
The present disclosure provides systems and methods for assessing a mental state of a subject in a single session or over multiple different sessions, using for example an automated module to present and/or formulate at least one query based in part on one or more target mental states to be assessed. The query may be configured to elicit at least one response from the subject. The query may be transmitted in an audio, visual, and/or textual format to the subject to elicit the response. Data comprising the response from the subject can be received. The data can be processed using one or more individual, joint, or fused models. One or more assessments of the mental state associated with the subject can be generated for the single session, for each of the multiple different sessions, or upon completion of one or more sessions of the multiple different sessions.
