Design And Implementation Of Children's Language Behavior Assessment System Based On Iflytek Cloud

With the development of children's language and mental health,the problem of child language development has received more and more attention from the society.As a result,parents and medical workers hope to develop an assessment tool for children's language behavior development.It can effectively analyze the children's daily speech,especially in the process of preventing children's language barriers.Therefore,the development of a child language behavior development assessment tool has important social significance.IFlytek voice cloud platform is the international leading voice recognition platform,its developed voice transfer service can be used for the double voice separation and long-time audio recognition in a specific scene,and the response speed is fast.For the analysis of complex long time audio workers,can save a lot of human resources and time.This paper mainly aims at the 4-year-old to 6-year-old children,using the J2EE mainstream development framework,designed and developed a child language behavior development assessment system based on iFlytek.This system based on the specific design model,starting from the reality,collect the real children daily voice as the training data of the system,through the code to achieve the corresponding functions.Specific elements include:(1)Design and implementation of child language behavior development assessment system.The users of the system are divided into two categories of doctors and medical powder,the user login system,upload children daily voice files,the system first,the children's voice file preprocessing,namely,the video format conversion technology using FFmpeg to format the audio files,and cut into suitable for the cloud processing audio,and then the preprocessing audio sequence uploaded to iFlytek for voice recognition.Finally,the scud recognition return result set for word segmentation statistics,to evaluate the number of words and words expressed by the child.(2)To evaluate and analyze the development evaluation system of child language behavior development.Using the method of manual transcription,the results of child language behavior development assessment system are compared with the manual transcription results,and the correctness of the evaluation results of the system is analyzed.The system can effectively reduce the burden of medical workers,and provides a good solution for the prevention of children's language barriers.
