类似的应用发展到＆QUOT;谷歌现在＆QUOT; - 是否有可能使用语音识别无键输入？ [英] Development of application similar to "Google now" - is it possible to use voice recognition without key input?

问题描述

我想开发使用 TTS 引擎和语音识别一个很酷的应用程序。到目前为止，这是确定的，但我想要更多。我想创建一个服务，（我觉得服务是正确的方式），这始终是听，当有人说确定谷歌或别的东西时，语音识别开始，像谷歌现在。例如，如果你说确定谷歌现在谷歌开始。我不知道从哪里开始，所以我直接问这里是否有可能。我试图寻找在[这里]这个线程（<一href="http://stackoverflow.com/questions/20312563/listening-for-keywords-at-all-times-like-ok-google-on-4-4">Listening在任何时候都关键字，如[确定谷歌＆QUOT;对4.4 ）和最后的答案谈到了服务，我想。有人可以帮助我与我的code？

I'm trying to develop a cool application that uses the TTS engine and speech recognition. So far it's ok but I want more. I would like to create a service (I think a service is the right way), that is always "listening" and when someone says "ok google" or something else , the speech recognition starts, like google now. For example, if you say "ok google" google now starts. I don't know where to start so I'm asking directly here if it's possible. I tried looking at this thread [here] (Listening for keywords at all times, like "Ok google" on 4.4) and the last answer talked about a service, as I thought. Can someone help me with my code?

例如，这是code通过点击一个按钮来启动语音识别：

For example this is the code to start speech recognition by tapping a button:

/**
 * Instruct the app to listen for user speech input
 */
private void listenToSpeech() {
    //start the speech recognition intent passing required data
    Intent listenIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    //indicate package
    listenIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
    //message to display while listening
    listenIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say a word!");
    //set speech model
    listenIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    //specify number of results to retrieve
    listenIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
    //start listening
    startActivityForResult(listenIntent, VR_REQUEST);
}

你觉得有可能启动 listenIntent 只有声音，没有pressing任何按钮？这就是我的意思。

Do you think it's possible to start that listenIntent only with voice and without pressing any button? This is what i mean.

和有一个由机器人提供的没有这样的API来进行这样的操作。

and there is No such API provided by Android to perform such operation.

注意 - 它非常消耗CPU和电池消耗听在后台所有的时间。
