Development And Application Of Intelligent Voice Interaction System

With the rapid development of computer network technology and artificial intelligence technology,people have also put forward new prospects in the way of human-computer interaction.The study of convenient and efficient human-computer interaction methods has been sought after by more and more experts and scholars.The application of speech,the most natural way of interaction,to achieve human-machine interaction,can effectively improve people's shortcomings such as slow input efficiency and error-proneness in using traditional interaction methods such as buttons.Therefore,the application of speech recognition control technology in human-computer interaction has become more and more,and it has gradually become a technological hot spot with great value in the current era.This dissertation focuses on the development of voice control system in smart home,integrates voice recognition technology and radio frequency infrared control technology and applies it in smart home devices to design intelligent voice interaction hardware.This hardware is used as home voice portal.It can achieve effective control of home electronic devices by voice,and can access the voice cloud database to search for favorite music and music programs,listen to weather forecasts,and set alarms.At the same time,this paper also makes a brief study in the algorithm model of speech recognition.Theoretical analysis and comparison are made between the two main speech recognition algorithms.The traditional DTW algorithm is improved and optimized and applied to speech recognition.The intelligent speech interaction system is designed.Finally,the function of the system is tested as a whole.The test data shows that the man-machine speech interaction terminal designed in this paper can achieve complete speech recognition.And intelligent voice control,recognition speed,can meet people's needs for high efficiency,simple and rapid human-computer interaction.
