This paper shows how a society of agents can self-organize a shared vocalization system that is discrete, combinatorial and has a form of primitive phonotactics, starting from holistic inarticulate vo...
子带特征参数在家禽应激发声识别中的应用（Application of Subband Feature of Poultry Vocalization for Identifying Their Status）

基于子带梅尔频谱质心的优化特征参数（SMSC），研究了35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，并通过建立支持向量机模型（SVM），比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。试验结果表明，采用加入梅尔频谱质心修正的特征参数，在分类正确识别率方面平均提高了24%。
