Android实现语音识别 && 讯飞平台语音识别语音播报
Android语音识别，借助于云端技术能够识别用户的语音输入，包括语音控制等技术，下面咱们将利用Google提供的Api实现这一功能。功能点为：经过用户语音将用户输入的语音识别出来，并打印在列表上。java
首先创建以下的一个activity，并在button下创建一个listview控件（用来回显语言识别到的项目）。android
代码以下：数组
package com.example.speechreg;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager; //用于查找本地应用软件包相关的类
import android.content.pm.ResolveInfo; //从系统IntentFilter返回的信息
import android.os.Bundle;
import android.speech.RecognizerIntent; //语音识别类
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter; //相同数据用数组存储的匹配转化类
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;
/**
* Sample code that invokes the speech recognition intent API.
*/
public class MainActivity extends Activity implements OnClickListener {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234; //startActivityForResult操做要求的标识码
private ListView mList;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.voice_recognition);
Button speakButton = (Button) findViewById(R.id.btn_speak);
mList = (ListView) findViewById(R.id.listView1);
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0); //经过全局包管理器及特定intent，查找系统是否有语音识别的服务程序
if (activities.size() != 0) {
speakButton.setOnClickListener(this); //若是存在该activity
} else {
speakButton.setEnabled(false);
speakButton.setText("Recognizer not present"); //不然将BUTTON显示值修改，并设置成不可选
}
}
public void onClick(View v) { //OnClickListener中的要override的函数
if (v.getId() == R.id.btn_speak) {
startVoiceRecognitionActivity();
}
}
private void startVoiceRecognitionActivity() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
"Speech recognition demo"); //设置语音识别Intent调用的特定属性参数
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE); 启动一个要求有返回值的activity调用
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) { //该函数非接口内也非抽象函数，为什么会Override？
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); //解析存储识别返回的结果
mList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, matches)); //在listview中显示结果
}
super.onActivityResult(requestCode, resultCode, data);
}
}
运行结果以下，它会自动调用谷歌语音识别的服务activity，并返回特定activity执行的结果。app
