基于LD3320的语音识别系统在家庭电路中的模拟应用

Simulation Application of Speech Recognition System Based on LD3320 in Home Circuit

该研究旨在为行动不便的残障人士或者老年人的家居生活提供便利和帮助,使他们能够通过语音识别系统对家用电器、照明系统、门窗开关等实现智能控制。通过查找资料,对比参数、价格、识别率等方面的信息,最终采用了基于LD3320的语音识别系统进行家庭电路控制模拟应用。系统由4部分构成,即:YS-LD语音识别模块、STM32单片机控制单元、LED显示单元、继电器输出单元。LD3320语音识别芯片感应语音——通过STM32单片机运算分析——发出信号——控制继电器——电器工作。经过测试,本套系统的语音辨识率高达90%,无需用户自行建立语音模型及开发语音识别算法,降低了应用开发的技术门槛,有利于推广应用。

The study aims at to provide convenience and assistance for the mobility of the disabled or elderly home life, so that they can through speech recognition system of household electrical appliances, lighting systems, door and window switch to realize intelligent control. By looking up the information, the information of the parameters, the price and the rate of recognition, the LD3320 based speech recognition system is used to control the home circuit. System consists of four parts, namely： YS-LD speech recognition module, STM32 microcontroller control unit, LED display unit, relay output unit. LD3320 speech recognition chip-based on the STM32 microcontroller operation analysis-a signal. After testing, the system of speech recognition rate is as high as 90%, without requiring the user to create their own speech model and the development of speech recognition algorithm, the lower the threshold of the development and application of technology, is conducive to the promotion and application.
