Frequential Characterization of Healthy and Pathologic Newborns Cries

Y. Kheddache, C. Tadj

In this paper, we present recent developments in the characterization of healthy and pathologic cries of newborns. We have identified and quantified acoustic characteristics that appear the most relevant in differentiating between pathological and healthy cries; such as fundamental frequency (F0), irregularity of F0 and presence of hyper-phonic modes. The results obtained are very encouraging, since the characteristics measured actually differentiate pathological cries from the cries of healthy babies.
