Android系統從1.6版本開始就支持TTS（Text-To-Speech）,即語音合成。可是android系統默認的TTS引擎:Pic TTS不支持中文。因此咱們得安裝本身的TTS引擎和語音包。html

在項目中，一開始用的是手說TTS，免費版的，感受聲音很不僵硬，不天然，不連貫。付費版的還要錢激活，若是不激活，限制每次只能度5個字，並且比免費版也好不了多少。最後採用了訊飛語音TTS1.0，發音連貫天然，我的感受很不錯了，之後就用它。java

介紹下使用方法：android

1.首先下載訊飛的語音包apk，以及語音引擎apk，安裝在手機上。api

2.進入系統設置-->語音輸入輸出設置-->勾選「訊飛語音合成" , 默認引擎「訊飛語音合成」, 語言「中文"。app

調用android自帶的TTS api，就可實現中文版語音合成。ide
