基于LD3320的语音识别智能垃圾桶设计

在互联网和自动化技术的不断发展的影响下，智能家居已经成为了当今物联网技术发展的重要热点方向之一。本设计基于ICRoute公司生产的非特定语音识别芯片LD3320，利用非特定语音识别算法实现垃圾桶的智能化声音识别和语音控制，完成语音控制垃圾桶各方向运动、非接触式智能开闭、容量检测功能。通过在模拟工作环境下对于设计正确识别率进行检测，证明系统在正常工作环境下的正确识别率达到88．4％，可以在2 m距离内有效完成设计动作和功能。

Design of speech recognition intelligent trash based on LD3320

With the development of Internet technology and automation, smart home technology has become the one of the most popular directions of the internet of things. The intelligent trash based on non specific speech recognition chip LD3320 made by ICRoute with non specific speech recognition algorithm to finish the intelligent voice recognition and voice control and achieve the function of omnidirectional movement, non contact intelligent opening and closing, measurement. In the simulative environment of the working, the experiment tests the rate of correct recognition. In the normal working environment, the correct recognition rate reaches 88.4%, proving the design can finish the functions and actions within 2 meters.
