如何在android手机中使用语音识别而不显示烦人的对话框
如何在android手机中使用语音识别而不显示烦人的对话框
提问于 2011-06-11 23:56:44
在不修改android API的情况下可以做到吗？我找到了一篇关于这方面的文章。有一条评论说我应该对android API进行修改。但它没有说明如何进行修改。有谁能给我一些如何做到这一点的建议？谢谢!
我找到了这篇文章；SpeechRecognizer他的需求几乎和我的一样。这对我来说是一个很好的参考资料！
我完全解决了这个问题。
我用谷歌搜索了一个有用的示例代码from this China website这是我的源代码
package voice.recognition.test;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
import android.util.Log;
public class voiceRecognitionTest extends Activity implements OnClickListener
{
private TextView mText;
private SpeechRecognizer sr;
private static final String TAG = "MyStt3Activity";
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button speakButton = (Button) findViewById(R.id.btn_speak);
mText = (TextView) findViewById(R.id.textView1);
speakButton.setOnClickListener(this);
sr = SpeechRecognizer.createSpeechRecognizer(this);
sr.setRecognitionListener(new listener());
}
class listener implements RecognitionListener
{
public void onReadyForSpeech(Bundle params)
{
Log.d(TAG, "onReadyForSpeech");
}
public void onBeginningOfSpeech()
{
Log.d(TAG, "onBeginningOfSpeech");
}
public void onRmsChanged(float rmsdB)
{
Log.d(TAG, "onRmsChanged");
}
public void onBufferReceived(byte[] buffer)
{
Log.d(TAG, "onBufferReceived");
}
public void onEndOfSpeech()
{
Log.d(TAG, "onEndofSpeech");
}
public void onError(int error)
{
Log.d(TAG, "error " + error);
mText.setText("error " + error);
}
public void onResults(Bundle results)
{
String str = new String();
Log.d(TAG, "onResults " + results);
ArrayList data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for (int i = 0; i < data.size(); i++)
{
Log.d(TAG, "result " + data.get(i));
str += data.get(i);
}
mText.setText("results: "+String.valueOf(data.size()));
}
public void onPartialResults(Bundle partialResults)
{
Log.d(TAG, "onPartialResults");
}
public void onEvent(int eventType, Bundle params)
{
Log.d(TAG, "onEvent " + eventType);
}
}
public void onClick(View v) {
if (v.getId() == R.id.btn_speak)
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5);
sr.startListening(intent);
Log.i("111111","11111111");
}
}
}请务必在调试后删除恼人的日志！

使用SpeechRecognizer接口。您的应用程序需要具有RECORD_AUDIO权限，然后您可以创建一个SpeechRecognizer，给它一个RecognitionListener，然后调用它的startListening方法。当语音识别器准备好开始监听语音时，以及当它接收语音并将其转换为文本时，您将获得对侦听器的回调。

感谢你贴出这篇文章！我发现在oncreate中定义onclick监听器很有帮助：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mText = (TextView) findViewById(R.id.textView1);
MyRecognitionListener listener = new MyRecognitionListener();
sr = SpeechRecognizer.createSpeechRecognizer(this);
sr.setRecognitionListener(listener);
findViewById(R.id.button1).setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v)
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");
sr.startListening(intent);
}
});
