Abstract
A method and a computer program are given to measure the jitter of the fundamental frequency of infants’ cries. The jitter curve depends on the of slope of the fundamental frequency curve and it also shows differences between hunger, pain and frustration cries. For an objective evaluation of jitter abnormities, a parameter — the so‐called cry‐jitter index — is used. Statistical analyses showed significant differences in the cry‐jitter indexes of normal versus premature infants.Keywords
