基于android的语音识别

须知少年凌云志，曾许人间第一流。这篇文章主要讲述基于android的语音识别相关的知识，希望能为你提供帮助。
1.注册账户，添加应用

2.针对android平台的选择应用，下载SDK

3.将SDK的libs下文件拷贝到工程的libs目录下

4.添加用户权限

< uses-permission android:name="android.permission.INTERNET"/> < uses-permission android:name="android.permission.RECORD_AUDIO"/> < uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> < uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> < uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/> < uses-permission android:name="android.permission.READ_PHONE_STATE"/> < uses-permission android:name="android.permission.READ_CONTACTS"/> < uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> < uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> < uses-permission android:name="android.permission.WRITE_SETTINGS"/> < uses-permission android:name="android.permission.CAMERA"/>

5.初始化语音配置对象

//初始化语音配置对象，必须，这样才能使用MSC语音服务 SpeechUtility.createUtility(this, SpeechConstant.APPID+"=59454d78");

6.拷贝assets目录下资源文件到android工程的assets目录

7.识别代码

//创建语音识别对话框 RecognizerDialog rd = new RecognizerDialog(this,null); //设置参数accent,language等参数 rd.setParameter(SpeechConstant.LANGUAGE,"zh_cn"); //中文 rd.setParameter(SpeechConstant.ACCENT,"mandarin"); //普通话 //设置回调接口 rd.setListener(new RecognizerDialogListener() { @Override public void onResult(RecognizerResult recognizerResult, boolean b) { //获取返回结果 Stringresult = recognizerResult.getResultString(); Log.e("result",result); Log.e("b",b+""); }@Override public void onError(SpeechError speechError) {} }); //显示对话框 rd.show();

8.由于返回的是json字符串所以还得解析出来才能使用

result:{"sn":2,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"？"}]}]}

【基于android的语音识别】9.解析Json字符串

/** * 解析json串 * @param result */ protected String parseJsonData(String json) { // 使用Gson来解析Json串 Gson gson = new Gson(); VoiceBean bean = gson.fromJson(json, VoiceBean.class); ArrayList< WS> ws = bean.ws; StringBuffer sb = new StringBuffer(); for (WS ws2 : ws) { String info = ws2.cw.get(0).w; sb.append(info); } return sb.toString(); }

package com.example.chat; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import com.example.chat.VoiceBean.WS; import com.google.gson.Gson; import com.iflytek.cloud.RecognizerResult; import com.iflytek.cloud.SpeechConstant; import com.iflytek.cloud.SpeechError; import com.iflytek.cloud.SpeechSynthesizer; import com.iflytek.cloud.SpeechUtility; import com.iflytek.cloud.ui.RecognizerDialog; import com.iflytek.cloud.ui.RecognizerDialogListener; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.ListView; public class MainActivity extends Activity {StringBuffer strbuf; ListView mlv; private List< TalkBean> lists; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //初始化语音配置对象，必须，这样才能使用MSC语音服务 SpeechUtility.createUtility(this, SpeechConstant.APPID+"=59454d78"); mlv = (ListView) findViewById(R.id.lv); lists = new ArrayList< TalkBean> (); }public void click(View view){ //创建语音识别对话框 RecognizerDialog rd = new RecognizerDialog(this,null); //设置参数accent,language等参数 rd.setParameter(SpeechConstant.LANGUAGE,"zh_cn"); //中文 rd.setParameter(SpeechConstant.ACCENT,"mandarin"); //普通话 strbuf = new StringBuffer(); //设置回调接口 rd.setListener(new RecognizerDialogListener() {@Override public void onResult(RecognizerResult arg0, boolean arg1) { // TODO Auto-generated method stub Stringresult = arg0.getResultString(); String data = https://www.songbingjia.com/android/parseJsonData(result); Log.e("data",data); strbuf.append(data); if(arg1){//回话结束 String voice = strbuf.toString(); Log.e("result",voice); }Log.e("b",arg1+""); }@Override public void onError(SpeechError arg0) { // TODO Auto-generated method stub} }); //显示对话框 rd.show(); } /** * 解析json串 * @param result */ protected String parseJsonData(String json) { // 使用Gson来解析Json串 Gson gson = new Gson(); VoiceBean bean = gson.fromJson(json, VoiceBean.class); ArrayList< WS> ws = bean.ws; StringBuffer sb = new StringBuffer(); for (WS ws2 : ws) { String info = ws2.cw.get(0).w; sb.append(info); } return sb.toString(); }
