蘋果的iphone 有語音識別用的是Google 的技術,作爲Google 力推的Android 天然會將其核心技術往Android 系統裏面植入,並結合google 的雲端技術將其發揚光大。
因此Google Voice Recognition在Android 的實現就變得極其輕鬆。
語音識別,藉助於雲端技術能夠識別用戶的語音輸入,包括語音控制等技術,下面咱們將利用Google 提供的Api 實現這一功能。
功能點爲:經過用戶語音將用戶輸入的語音識別出來,並打印在列表上。
功能界面以下:
用戶經過點擊speak按鈕顯示界面:
用戶說完話後,將提交到雲端搜索:
在雲端搜索完成後,返回打印數據:
