As people's living standard and the degree of mass culture have been constantly improved, many families are caring more about the healthy growth of early childhood. In this paper, based on the research of domestic and foreign experts and scholars: the guardians (such as parents) take appropriate intervention on children at the early stage can effectively promote children's language and cognitive ability development, and the intervention has obvious effect on the autistic spectrum disorders of children. This paper presents a system for analyzing children's speech signal, calculating the guardian’s language words, the number of children‘s verbal words and the number of guardian and children's dialogue rotation times by voice signal processing and pattern recognition technology. And related personnels use these indicators to analysis the development of children's language and cognitive ability, then adopting appropriate measures for children and providing the basis for decision-making criteria, so as to promote the development of children's language and cognitive status.
