Android TTS 實戰(zhàn)之中文語音識別

不能用中文的語音識別感覺很不爽，下午終于弄出來了，網(wǎng)上查找資料說要使用開源項目eyes-free或者下載科大訊飛的 jar 包。但我是用谷歌的 voice search （現(xiàn)在有支持中文了）來做的。

名詞解釋

?語音搜索（voice search）是一種語音識別技術(shù)，它使用戶能夠通過大聲說出條目來進行搜索，而不用將它們輸入到搜索欄來搜索。智能手機以及其他小型的具有網(wǎng)絡功能的移動設(shè)備的劇增激發(fā)了大家對語音搜索的興趣。

　　語音搜索（voice search）的應用包括：

進行搜索引擎查詢。明確具體的要求。請求具體信息，如股票報價。啟動程序并選擇選項。尋找音頻或視頻文件里的內(nèi)容。語音撥號。

　　語音搜索（voice search）通常是一個應用軟件，但它也可以是一個服務。語音搜索應用程序，如具有語音功能的谷歌移動和iPhone的Vlingo，依靠的是語音識別程序。
