1. A method for assessing health of an individual using a distributed system that includes (i) a computer server on which a health management platform is executing and (ii) an electronic device on which a computer program is executing, the method comprising:
monitoring, by the computer program, a location of the electronic device so as to establish when the electronic device is located proximate to a predetermined location;
generating, by the computer program, a notification that prompts the individual to create an audio recording in response to a determination that the electronic device is located proximate to the predetermined location;
applying, by the computer program, a noise reduction algorithm to improve signal-to-noise (SNR) ratio of audio media that is recorded by the electronic device and that is representative of the audio recording created by the individual, prior to transmitting the audio media to the health management platform;
transmitting, by the computer program, the audio media to the health management platform over a network via which the electronic device is communicatively connected to the computer server;
processing, by the health management platform, the audio media using an algorithm that objectively characterizes a frequency-domain feature and produces, as output, a value for the frequency-domain feature;
verifying, by the health management platform, an identity of the individual based on a comparison of the value produced for the frequency-domain feature to a reference value that is known to be representative of the individual; and
in response to verifying the identity of the individual,
establishing whether the individual has experienced a change in health based on the value produced for the frequency-domain feature.
