離線功能指南：
1. 在百度語音開放平臺(tái)注冊(cè)應(yīng)用，http://yuyin.baidu.com/app
2. 為您的應(yīng)用的“申請(qǐng)離線授權(quán)頁面”，填寫程序包名
3. 在當(dāng)前應(yīng)用的AndroidManifest.xml中填寫相應(yīng)的APP_ID（或在代碼中設(shè)置appid參數(shù)）
4. 根據(jù)場(chǎng)景下載并集成相應(yīng)的資源，見http://yuyin.baidu.com/docs/asr/131和http://yuyin.baidu.com/asr/download
另外需要注意的是離線功能只是在線功能的“增強(qiáng)”，不能永久不聯(lián)網(wǎng)使用（特別是首次使用）。
