    • The present invention concerns an automatic method for measuring a baby's cry, comprising the following step: A. having N samples ρ(i), for i=O, 1, . . . , (N−1), of an acoustic signal p(t) representing the cry, sampled at a sampling frequencŷ 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.
    • 本发明涉及一种用于测量婴儿哭泣的自动方法,包括以下步骤:A.具有N个样本rho(i),对于i = 0,1,...。 。 。 ,(N-1)表示在采样频率下持续时间段P的采样的表示哭泣的声信号p(t); 该方法的特征在于,其通过从包括以下的组中选择的一个或多个声学参数的函数AF将音分信号p(t)分配给声信号p(t): - 均方根或均方根值prms P期间的声信号p(t) - 声学信号p(t)的基音或音调频率F 0,即在时间段P中发生声学信号p(t)的频谱中的峰值的最小频率; 以及在周期P中的声学信号p(t)的幅度和频率调制的配置。本发明还涉及执行该方法的装置。
