苹果的iphone的语音识别功能使用的是Google的技术，做为Google力推的Android自然会将其核心技术植入到Android系统里面，并结合google的云端技术将其发扬光大。
所以Google Voice Recognition在Android中的实现就变得非常轻松。
Android语音识别，借助于云端技术可以识别用户的语音输入，包括语音控制等技术，下面我们将利用Google提供的Api实现这一功能。
功能点为：通过用户语音将用户输入的语音识别出来，并打印在列表上。
功能界面如下：
用户通过点击speak按钮显示界面：
用户说完话后，将提交到云端搜索：
在云端搜索完成后，返回打印数据：
完整代码如下：

Google的语音识别是有目共睹的，所以Android上面也是沾了大光了，用起来简单至极。过程如下：1、启动语音识别Activity2、这里处理语音（传到google服务器处理）3、结果以Acitivity的结果返回（onActivityResult）主要用到的类为下面的例子参考了API Demo。package com.
import java.util.ArrayL
import java.util.L
import android.app.A
import android.content.I
import android.content.pm.PackageM
import android.content.pm.ResolveI
import android.os.B
import android.speech.RecognizerI
import android.view.V
import android.view.View.OnClickL
import android.widget.B
import android.widget.TextV
public class VoiceRecognitionDemoActivity extends Activity {
private static final String TAG = &VoiceRecognition&;
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;
private TextView textV
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initWidget();
// Check to see if a recognition activity is present
PackageManager pm = getPackageManager();
List&ResolveInfo& activities = pm.queryIntentActivities(
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() != 0) {
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
startVoiceRecognitionActivity();
button.setEnabled(false);
button.setText(&Recognizer not present&);
private void initWidget()
textView = (TextView)findViewById(R.id.tv);
button = (Button)findViewById(R.id.btn);
* Fire an intent to start the speech recognition activity.
private void startVoiceRecognitionActivity() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// Display an hint to the user about what he should say.
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, &请说标准普通话&);//注意不要硬编码
// Given an hint to the recognizer about what the user is going to say
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
// Specify how many results you want to receive. The results will be sorted
// where the first result is the one with higher confidence.
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);//通常情况下，第一个结果是最准确的。
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
// Fill the list view with the strings the recognizer thought it could have heard
ArrayList&String& matches = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
StringBuilder stringBuilder = new StringBuilder();
int Size = matches.size();
for(int i=0;i&S++i)
stringBuilder.append(matches.get(i));
stringBuilder.append(&\n&);
textView.setText(stringBuilder);
super.onActivityResult(requestCode, resultCode, data);
}结论：在wifi（家里的，1兆带宽）状态下，识别速度飞快。语音包是买手机时预装好的。识别率很高。中文、英文、数字都能很好的识别。用手机的gprs，效果不尽如人意。几次识别都用了30秒左右的时间，体验很糟。
