关于Android利用RecognizerIntent识别语音并简单实现打电话，详细看实现代码例如以下：

package com.example.recognizerintentactivity;

import java.util.ArrayList;

import android.app.Activity;

import android.content.Intent;

import android.net.Uri;

import android.os.Bundle;

import android.speech.RecognizerIntent;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;

public class MainActivity extends Activity {

private Button btnReconizer;

private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

btnReconizer = (Button) this.findViewById(R.id.btnRecognizer);

btnReconizer.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

try {

// 通过Intent传递语音识别的模式，开启语音

Intent intent = new Intent(

RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

// 语言模式和自由模式的语音识别

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,

RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);

// 提示语音開始

intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "開始语音");

// 開始语音识别

startActivityForResult(intent,

VOICE_RECOGNITION_REQUEST_CODE);

} catch (Exception e) {

// TODO: handle exception

e.printStackTrace();

Toast.makeText(getApplicationContext(), "找不到语音设备", 1)

.show();

}

}

});

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// TODO Auto-generated method stub

// 回调获取从谷歌得到的数据

if (requestCode == VOICE_RECOGNITION_REQUEST_CODE

&& resultCode == RESULT_OK) {

// 取得语音的字符

ArrayList results = data

.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

String resultString = "";

for (int i = 0; i < results.size(); i++) {

resultString += results.get(i);

}

if(resultString.indexOf("喂") >-1){

String tel = "15100000000";

Intent intent = new Intent();

intent.setAction(Intent.ACTION_CALL);

intent.setData(Uri.parse("tel:" + tel));

startActivity(intent);

Toast.makeText(this,tel, 1).show();

}else{

Toast.makeText(this, "没找到要拨打的电话", 1).show();

}

}

super.onActivityResult(requestCode, resultCode, data);

}

}

这里，我们须要注意的是，须要用到两个权限。一个是网络资源。一个是打电话的这个动作权限，因此，我们须要改动 AndroidMainfest.xml添加两条内容。例如以下
