简介:一个修改Parzen窗户方法,在低频率使分辨率高并且把光滑放在高频率,被建议获得统计模型。然后,当长句子被处理时,利用统计模型的一个性分类方法被建议,它有性分类的98%精确性。由男声音和女性表示的分离,与不同情感训练样品的讲话的平均数和标准差被用来创造相应情感模型。然后在测试样品和沥青的统计模型之间的Bhattacharyya距离,在沥青的speech.The正规化为情感识别被利用因为男声音和女声音也被考虑,以便说明他们直到一个一致空格。最后,讲话情感识别实验基于K最近的邻居显示出那,81%的正确的率被完成,在它仅仅是73.85%if的地方,传统的参数被利用。

简介:AbstractImportance:Parents take the lead in parent-child interactions and their emotion regulation ability and empathy during parenting may be associated with children’s emotional/behavioral problems. However, the specific mechanisms underlying these associations remain unclear.Objective:The present study aimed to explore the effect of parental empathy and emotional regulation on social competence and emotional/behavioral problems in school-age children.Methods:A questionnaire-based survey was conducted with 274 parents of 8-11-year-old children using Achenbach’s Child Behavior Checklist, the Emotion Regulation Questionnaire, and the Questionnaire of Cognitive and Affective Empathy.Results:Children with emotional/behavioral problems (n = 37) had relatively lower social competence than children in a matched control group (n = 37). Compared with the parents of children in the control group, parents of children with emotional/behavioral problems had significantly lower cognitive empathy scores, mainly manifested by low perspective-taking and online simulation abilities. Mediation analysis showed that parental cognitive empathy had an indirect effect on children’s emotional/behavioral problems through children’s social competence.Interpretation:Parental empathy may have a subtle influence on the social competence of school-aged children, which further affects the severity of children’s emotional/behavioral problems.
