We aim to help parents understand more about their children's emotions and mental well-being through seamless tracking of the emotions and FFT of the children.

Cry signals can be described by their features within two common domains: (1) the time domain and (2) frequency domain. From either of the mentioned domains, a number of significant characteristics can be extracted (Scherer, 1982). In this section, we describe the different domain features applied at different levels of our work.

1. Time-domain features a. Intensity. The intensity is also called the loudness, and it is related to the amplitude of the signal. It represents the amount of energy a sound has per unit area. The intensity is defined by the logarithmic measure of a signal section of length N in decibels as follows:

I=10  log (∑n=1Ns2(n)w(n)),

where w is a window function and s(n) is the amplitude of the signal.

Intensity is an essential feature widely used in different applications, such as music mood detection, and an accuracy rate of 99% is achieved, proving the good performance of intensity features.

This model is backed by the research paper by Scherer K. R. (1982). “ The assessment of vocal expression in infants and children,” in Measuring Emotions in Infants and Children.
