Infant Crying, a Bioacoustic Prognostic Signal for Neurodevelopment

The objective of the Baby's cry 1000/100 study is to evaluate the acoustic characteristics of crying at birth, of term and premature babies and to correlate them with neurodevelopmental outcomes at 2 years of age to see if the bioacoustic characteristics of crying at birth could be predictive of the baby's neurofunctional integrity.

To achieve this objective, the investigators wish to document a large bank of recordings of the crying of term or premature babies by relying on deep learning and artificial intelligence approaches, making it possible to process large databases quickly, evaluate the links between acoustics of crying and clinical data at the birth of full-term babies who will benefit from systematic neurodevelopmental monitoring at 2 years (Bayley scale).
