Android Speech to Text Example
提问by Palagerini
I've looked at the Android example for VoiceRecognition, but I don't really understand what it is suppose to do or how it works. In the manifest there isn't any sort of main activity to run and so when I install the app on my phone I can't run it.
我已经查看了 VoiceRecognition 的 Android 示例，但我真的不明白它应该做什么或它是如何工作的。在清单中没有任何类型的主要活动要运行，因此当我在手机上安装应用程序时，我无法运行它。
I'm also trying to find a simple example of Speech to text that takes speech as input and outputs the text on the screen. Just so I can study it to see how it works, but I haven't been able to find any sort of example on the web that shows it.
我还试图找到一个简单的 Speech to text 示例，它将语音作为输入并在屏幕上输出文本。只是为了我可以研究它以了解它是如何工作的，但是我无法在网上找到任何显示它的示例。

I did it like that:
我是这样做的：
in onCreate:
在 onCreate 中：
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
In the method starting the voice recognition:
在启动语音识别的方法中：
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Voice recognition Demo...");
startActivityForResult(intent, REQUEST_CODE);
onActivityResult:
活动结果：
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK)
{
// Populate the wordsList with the String values the recognition engine thought it heard
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
}
}
Hope I'm not missing anything, been a time since. Drop me a note if something doesn't work. About the text output: I'm sure you can handle that once you have a populated matches array.
希望我没有错过任何东西，已经有一段时间了。如果有什么不起作用，请给我留言。关于文本输出：我相信一旦你有了一个填充的匹配数组，你就可以处理它。
