| Summary: | In recent years, the number of studies investigating possible noninvasive
health screening techniques for infants have increased exponentially.
Amongst those, one of the most prominent is health
screening based on the acoustic investigation of infant cry. Clinicians
involved in the field moved from visual inspection of the audible
spectrum to automatized analysis of cry samples using computer
software. A software that has been more widely adopted in recent
years is Praat, a free software designed for speech analysis. Unfortunately,
the software’s default settings are not suitable for investigation
of cry samples, yet rarely used settings are reported in final
manuscripts. In this article, we tested 4 different computer generated
signals, with frequency features comparable to cry frequencies,
and 3 real cry samples using both Praat’s standards and tuned settings.
Our results highlight the importance of properly tuning software’s
parameters when expanding their field of usage, and provide
a starting point for the development of optimal Praat algorithm’s parameters
