The aim of this pilot study cry analysis of brain injured asphyxiated infants, aiming to identify parameters that might predict clinical oucome. Thirteen controls and six asphyxiated subjects with MRI evident lesions were included. Spectrographic analysis of manipulation cries showed that vibrato contours were significantly more frequent in the brain lesioned group than in the controls, and prevalent in two subjects whose outcome was spastic displegy and death. F0 parameters were significantly lower in infants with midbrain injuries, this finding is in contrast with previous literature.

Index Terms. infant cry, neonatal asphyxia, brain injury, physioacoustic, spectrographic analysis.
