Abstract
Introduction: Newborn cries exhibit a richness of melody and rhythmicity, yet their rhythmic features have been less studied.
Methods: In this study, we analyzed the amplitude modulation of 1,884 cries from 30 Chinese newborns.
Results: The group-averaged amplitude modulation spectrum revealed an evident increase in energy between 0.5 and 8 Hz, peaking around 2 Hz. The peak frequency for individual child averaged at around 3 Hz (SD = 1.3 Hz), with the majority of which lied below 5 Hz.
Conclusion: This study is the first to demonstrate that newborn cries contain increased energy in slower-rate amplitude modulation frequencies associated with prosodic feet and syllabic rhythms in speech, underscoring the important role of rhythmic information in early language acquisition.
期刊介绍：
Published since 1947, ''Folia Phoniatrica et Logopaedica'' provides a forum for international research on the anatomy, physiology, and pathology of structures of the speech, language, and hearing mechanisms. Original papers published in this journal report new findings on basic function, assessment, management, and test development in communication sciences and disorders, as well as experiments designed to test specific theories of speech, language, and hearing function. Review papers of high quality are also welcomed.
