AUTOMATIC METHOD FOR MEASURING A BABY'S, PARTICULARLY A NEWBORN'S, CRY, AND RELATED APPARATUS

摘要

The present invention concerns an automatic method for measuring a baby's cry, comprising the following step: A. having N samples ?(i), for i = O, 1,..., (N-I), of an acoustic signal p(t) representing the cry, sampled at a sampling frequency^ for a period of duration P; the method being characterised in that it assigns a score PainScore to the acoustic signal p(t) by means of a function AF of one or more acoustic parameters selected from the group comprising: - a root-mean-square or rms value prms of the acoustic signal p(t) in the period P; - a fundamental or pitch frequency F0 of the acoustic signal p(t), i.e. the minimum frequency at which a peak in the spectrum of the acoustic signal p(t) occurs in the period P; and - a configuration of amplitude and frequency modulation of the acoustic signal p(t) in the period P. The invention further concerns the apparatus performing the method.
