大学老师介绍给我们的调试工具无法发挥功能,故我必须选用与该模块匹配的调试工具以便于电脑和单片机的成功通信。具体的调试方法如下:第一步是利用串口CH340或PL2303实现该语音模

摘  要:崭新的时代迎来了多媒体时代的发展和数字化社会的普及,方便快捷的智能生活方式日益受到人们的青睐,家用电器的控制方式不仅仅拘泥于按键、触屏等近距离操控方式,高效安全的声音控制开关给人们对家用设备进行操作与管理带来了便利,给予人类以智能、舒适的生活方式。语音识别技术发展迅猛,语音识别技术已广泛地在智慧家电中的应用。

智能语音家电控制系统就其本质来说上为一个可解放双手的声控制电子开关,代替了以往的传统手动开关。此系统以STM8S105K4T6和SX-ASR-A模块为硬件核心,SX-ASR-A模块对信息进行处理,并对开关进行控制,SX-ASR-A模块通过外界的麦克风采集声音信号,提取语音持征,然后和SX-ASR-A模块语音指令列表中的关键词或关键字匹配,最后找出该语音指令列表中得分最高的以十六进制指令反馈给单片机,单片机得到识别的指令后,再输出对应的信号通过继电器实现对家用电器的控制。

本设计所开发的家用声控开关系统,安全系数高,系统功能完善,反应速度灵敏,基本满足了市场对语音智能控制家电的需求,达到了预期效果。

Household sound control switch

Abstract:The new era ushered in the development of multimedia era and the popularity of digitalized society, the convenient and smart way of life is increasingly favored by people. The control method of household appliances is not only rigidly controlled by buttons, touch screens, etc., but also the efficient and safe sound control switch. People bring convenience to the operation and management of home appliances and give humans a smart and comfortable lifestyle.

Speech recognition technology has developed rapidly. Speech recognition technology has been widely used in smart home appliances. The intelligent voice home appliance control system is, by its very nature, an electronic control switch capable of releasing both hands instead of the conventional manual switch. The system uses the STM8S105K4T6 and SX-ASR-A modules as hardware cores. The SX-ASR-A module processes information and controls the switches. The SX-ASR-A module collects sound signals through external microphones and extracts voice signals. , and then match the keywords or keywords in the SX-ASR-A module voice instruction list, and finally find out that the highest score in the voice instruction list is fed back to the single-chip microcomputer in hexadecimal instructions, and the microcontroller receives the recognized instruction. Output corresponding signal through the relay to achieve control of household appliances.

The home-operated voice-activated switch system developed in this design has a high safety factor, complete system functions, and responsive speed. It basically meets the market's demand for voice-based intelligent control of home appliances and has achieved the desired results.
