广东东软学院本科毕业设计(论文) 基于智能语音识别控制技术的垃圾分类系统设计与实现Design and implementation of garbage classification system based on intelligent speech recognition control technology 摘 要随着中国社会的不断发展,中国环境污染问题日益严重,生活垃圾随着人口的增长越发增加。如今人们对生活环境逐渐重视起来,国家也开始深度倡导垃圾分类,进行垃圾的回收利用,但由于群众对于垃圾分类的认识度普遍不高,难以实现大范围垃圾分类规范化的目标;本设计主要分为硬件设计和软件设计。硬件部分将用到 STM32F103 微处理器模块、LD3320 语音识别模块、JQ8900 语音输出模块、舵机。主要是采用语音识别技术,通过对声音信号的处理,控制垃圾桶的运作。用户说出垃圾名称,LD3320 中根据语音的信息进行预加重、加窗分帧、端点检测的方法来处理语音信号,再进行语音转文本和比对关键词的操作进行识别用户所提供的垃圾名称属于哪一类垃圾。软件部分主要是控制对垃圾桶开关的驱动、语音的匹配处理、音频的交互式输出,由此完成人机交互式的智能语音垃圾桶的语音控制功能,呼叫可应答。此次设计可以广泛运用于大城市的家庭当中,能有效缓解大城市中垃圾分类处理能力和人们垃圾分类知识不相匹配的矛盾,日常家庭使用十分便利,还可以有垃圾分类的教育学习效果。这对提升国民垃圾常识有极大的帮助,更能为国家文明卫生城市的建设出一份力,同时在市场上有较好的前景。关键词: LD3320 模块 STM32F103 垃圾分类广东东软学院本科毕业设计(论文)AbstractWith the continuous development of Chinese society, the problem of environmental pollution in China is becoming more and more serious. Nowadays, people pay more and more attention to the living environment, and the country has started to advocate garbage classification and recycling. However, because the general public has a low awareness of garbage classification, it is difficult to achieve the goal of standardizing large-scale garbage classification. Designed for hardware and software. The hardware part will use STM32F103 microprocessor module, LD3320 speech recognition module, JQ8900 speech output module,...
