輕松實現(xiàn)Android語音識別功能
蘋果的iphone有語音識別用的是Google的技術(shù),做為Google力推的Android 自然會將其核心技術(shù)往Android 系統(tǒng)里面植入,并結(jié)合google 的云端技術(shù)將其發(fā)揚光大。
所以Google Voice Recognition在Android 的實現(xiàn)就變得極其輕松。
語音識別,借助于云端技術(shù)可以識別用戶的語音輸入,包括語音控制等技術(shù),下面我們將利用Google 提供的Api 實現(xiàn)這一功能。
功能點為:通過用戶語音將用戶輸入的語音識別出來,并打印在列表上。
