第一步：匯入jar包
再libs資料夾，匯入Msc.jar和Sunflower.jar，還有so包（這個要看手機是什麼晶片）。

第二步：程式碼

語音識別返回的是json，如：

{"sn":1,"ls":false,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"有"}],{"bg":0,"cw":[{"sc":0.00."w":"搞"}],{"bg":0,"cw":[{"sc":0.00,"w":"啊"}]}]}{"sn":2,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"。"}]}]}
