1. A system comprising:

  • a microphone configured to receive an input speech from an individual;

    an analog-to-digital (A/D) converter configured to convert the input speech from an analog form to a digital form and generate a digitized speech;

    a memory storing an executable code and an age estimation database including a plurality of age determinant formant-based feature vectors;

    a hardware processor executing the executable code to;

    receive the digitized speech from the A/D converter;

    identify a plurality of boundaries between a plurality of phonemes in the digitized speech;

    extract a plurality of formant-based feature vectors from one or more phonemes of the plurality of phonemes delineated by the plurality of boundaries, based on at least one of a formant position, a formant bandwidth, and a formant dispersion, wherein the formant dispersion is a geometric mean of the formant spacing;

    compare the plurality of formant-based feature vectors with the age determinant formant-based feature vectors of the age estimation database;

    estimate the age of the individual when the comparison finds a match in the age estimation database; and

    communicate an age-appropriate response to the individual based on the estimated age of the individual.
