沒錢買“智能”空調就沒轍了？自己動手做！STM32+LD3320程序

生活中我們使用空調的方法一般是：手持空調遙控器對著空調按下相應的按鍵發出命令，空調室內壁掛機接收到該命令并按命令對應的功能控制空調狀態改變，智能化程度較低。另一方面，現有的天貓精靈、小美等，對空調硬件要求高、需要安裝相關APP支持才能使用、無關信息（如，播報廣告不受用戶控制）等，用戶體驗有待進一步提高。

本系統設計最終要實現的效果是，比如，用戶直接以自然語言說出“模式設置，制冷模式”空調便自動工作在這種狀態下，其中模式可選擇地設置為制熱模式，制冷模式和自動模式。用戶說出“溫度設置，二十六度”空調要自動將溫度調整至二十六攝氏度，其中溫度值可選擇地設置為十七攝氏度至三十攝氏度之間的任意整數級別。用戶說出“風速設置，中速”空調要自動將出風流量調至“中速”，其中風速可選擇地設置為低速、中速、強勁、自動。從而實現通過自然人語音控制空調改變工作狀態。
