Systems and methods for digital speech-based evaluation of cognitive function

A computer-implemented method for evaluating cognitive function based on speech, the method comprising:

• receiving, with audio input circuitry, an input signal provided by a subject;
• processing, with signal processing circuitry, the input signal to detect one or more metrics of speech of the subject;
• and
• analyzing, with signal processing circuitry, the one or more metrics of speech using a speech assessment algorithm to generate an evaluation of a cognitive function of the subject.

A computer-implemented method for generating a speech assessment algorithm comprising a machine learning predictive model for evaluating cognitive function based on speech, the method comprising:

• receiving input signal comprising speech audio for a plurality of subjects;
• processing the input signal to detect one or more metrics of speech in the speech audio for the plurality of subjects;
• identifying classifications corresponding to cognitive function for the speech audio for the plurality of subjects;
• and
• training a model using machine learning based on a training data set comprising the one or more metrics of speech and the classifications identified in the speech audio, thereby generating a machine learning predictive model configured to generate an evaluation of cognitive function based on speech.
