1. A method of assessing expressive language development of a key child, comprising:

  • processing an audio recording taken in a language environment of the key child to identify segments of the audio recording that correspond to vocalizations of the key child;

    applying an adult automatic speech recognition phone decoder to the segments to identify each occurrence of a plurality of bi-phone categories and to determine a frequency count for each of the plurality of bi-phone categories, wherein each of the plurality of bi-phone categories corresponds to a pre-defined sequence of two phonemes, and wherein the plurality of bi-phone categories are a first subset of the vocalizations of the key child;

    determining a frequency distribution for the plurality of bi-phone categories based on the frequency counts for the plurality of bi-phone categories; and

    using the frequency distribution for the plurality of bi-phone categories in an age-based model to assess the expressive language development of the key child, wherein the age-based model is selected based on a chronological age of the key child and the age-based model includes a plurality of different weights associated with the plurality of bi-phone categories.
