STM32-based speech recognition systemAbstract:With the continuous updating of technology,the development of speechrecognition and automatic control will be an inevitable trend in the future.The more humanizedman-machine interaction method is voice interaction.The LD3320 chip can collect and recognizevoice information for voice recognition technology.The STC10L08XE chip is used as the maincontroller and this chip is used as the voice management system,and then the external storageand control circuit are combined for voice recognition and control.In this article,through the system design and feasibility experiment test,the speechrecognition system designed based on STM32 is explored,and the conversion of speech isrealized through the LD3320 chip,thereby achieving the effect of speech recognition control.Generally speaking,the operator issues the corresponding system language recognition command.After receiving the command,the system analyzes and searches internally and generates aresponse control signal,which controls the switch of the buzzer and LED light,and displays thecurrent time through the voice module For OLED screen.After testing,the project can completethe functions of the expected design,and can determine the LED light switch,buzzer switch,andtime display on the circuit board.In the overall structure narration of this article,the overall design process of the speechrecognition system is mainly described.The design of intelligent speech recognition system isrealized by adopting LD3320 chip technology,which further promotes the development of smarthome control system in China The feasibility of the corresponding test,and then combined withthe relevant factors affecting the system and according to the specific requirements of thesolution proposed in this article.Keywords:STM32 LD3200 Speech recognition systemMCUSignature of Supervisor:目录第一章绪论1.1研究背景及意义
