任何人都知道关于Android 4.1+离线语音识别API文档？ [英] Anyone knows about Android 4.1+ offline voice-recognition API documentation?

问题描述

我想在Android 4.1.2和4.3建立一个离线语音识别Android应用程序，而我试图访问到Android ASR API。我能找到的 HTTP（使用意向）与同步语音识别的所有信息：//developer.android.com/reference/android/speech/package-summary.html ，但没有有关异步识别（我想识别该文件中的音频内容）

I'm trying to build an offline voice recognition Android app on Android 4.1.2 and 4.3, and I'm trying to get access to Android ASR API. I could find all information related to synchronous voice recognition (using an intent) on http://developer.android.com/reference/android/speech/package-summary.html, but nothing about asynchronous recognition (I would like to recognize the audio content from a file).

有谁知道关于这个话题的API文档和教程？

Does anyone know about an API documentation and tutorials on this topic?

非常感谢！

编辑：非常感谢Kaarel你的答案。如果我把我尝试以另一种方式做：我有，我已经录制了讲话的音频文件，我想这个文件的内容发送到Android识别在离线模式下（例如，没有互联网连接） 。问题是，我已经能够使用Android语音识别，而用户说话（我称之为'同步'），而不是使用一个文件（用户没有说完如后，我称之为异步）。

Edit : Many thanks Kaarel for your answer. If I put what I'm trying to do in another way : I have an audio file where I have recorded a speech, and I would like to send the content of this file to the Android recognizer in offline mode (e.g. without internet connection). The issue is that I have been able to use Android speech recognition while the user is speaking (what I call 'synchronous'), but not using a file (e.g. after the user is done speaking, what I call asynchronous).

推荐答案

Android的语音API（如4.3版），不提供pre-录音的语音识别。此外，API不允许客户端宣布，语音识别应该发生的离线。

Android's speech API (as of version 4.3) does not offer speech recognition of a pre-recorded audio. Also, the API does not allow the client to declare that speech recognition should happen offline.
