System and method for emotion assessment
First Claim
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.

Abstract
A method of determining an emotion of an utterance. The method can include receiving the utterance at a processor-based device comprising an audio engine. The method also can include extracting emotion-related acoustic features from the utterance. The method additionally can include comparing the emotion-related acoustic features to a plurality of emotion models that are representative of emotions. The method further can include selecting a model from the plurality of emotion models based on the comparing the emotion-related acoustic features to the plurality of emotion models. The method additionally can include outputting the emotion of the utterance, wherein the emotion corresponds to the selected model. Other embodiments are provided.

11. A system for assessing expressive language development of a key child, comprising:
-
a processor-based device comprising an audio engine for 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; an adult automatic speech recognition phone decoder for processing the segments that correspond to the vocalizations of the key child 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; and an expressive language assessment component configured to determine a frequency distribution for the plurality of bi-phone categories based on the frequency counts for the plurality of bi-phone categories and configured to use 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
