用olami sdk语音识别语义理解做在线听书
olamisdk实现了把录音或者文字转化为用户可以理解的json字符串，本文使用olami sdk做了一个在线听书的demo，用的是喜马拉雅的在线听书sdk.基于eclipse开发环境，libs目录下jar和so文件如下：
olami-android-sdk.jar//olami sdk 的jar
afinal_0.5.1_bin.jar
litepal.jar
gson-2.2.4.jar
okhttp-2.4.0.jar
okhttp-urlconnection-2.2.0.jar
okio-1.4.0.jar
opensdk.jar //上面这几个都是喜马拉雅需要的jar
libspeex.so //olami sdk 需要用到speex压缩功能
libxmediaplayer.so // 喜马拉雅so
libxmediaplayer_x.so// 喜马拉雅so
概述：
VoiceSdkService中定义了OlamiVoiceRecognizer语音识别引擎，通过点击MusicActivity的开始button启动录音，录音结果在VoiceSdkService中的onResult()回调中拿到识别的Json字符串，在processServiceMessage()函数中处理后找到要听书的名称，然后进入BookUtil进行搜索，搜索到结果后通知VoiceSdkService进行播放，并通知MusicActivity更新播放进度等信息。

TextView 有两个，tv_name显示听书的名称, tv_totoal_time显示听书的总时间。
ProgressBar 实时刷新显示听书的进度

自定义MusicView比较简单，代码如下：
public class MusicView extendsRelativeLayout{
private Context mContext;
private Handler mHandler;
private TextView mTextViewName;
private TextView mTextViewTotalTime;
private ProgressBar mProgressBar;
public MusicView(Context context,AttributeSet attrs) {
super(context,attrs);
LayoutInflater inflater =(LayoutInflater) context.getSystemService(
context.LAYOUT_INFLATER_SERVICE);
RelativeLayout view = (RelativeLayout) inflater.inflate
(R.layout.layout_musicview,this,true);
mTextViewName = (TextView) view.findViewById(R.id.tv_name);
mTextViewTotalTime = (TextView) view.findViewById(R.id.tv_total_time);
mProgressBar = (ProgressBar)view.findViewById(R.id.progressbar_music);
}
public void initMusicView(Context context,Handler handler)
{
mContext = context;
mHandler = handler;
}
public void setMusicName(String name)
{//设置播放名称
mTextViewName.setText(name);
}
public void setProgress(int progress)
{//设置播放进度
mProgressBar.setProgress(progress);
}
public void setTotalTime(String time)
{//设置播放总时间
mTextViewTotalTime.setText(time);
}
}
布局效果图如下：
本文没有用bindservice的方式实现activity和service的消息通信。
MusicAcitity 和 VoiceSdkService中分别实现了一个CommunicationAssist的接口
public interface CommunicationAssist {
public void callBack(int what, int arg1, int arg2,Bundle data, Objectobj);
}
然后把他们分别实现CommunicationAssist接口的变量注册到OlamiApplication，这样通过OlamiApplication实现了MusicAcitity 和VoiceSdkService桥接。
1) 注册MusicActivity到VoiceSdkService的回调
public voidsetActivityToServiceListener(CommunicationAssist listener)
{
ActivityToServiceListener = listener;
}
这个是在VoiceSdkService中调用setActivityToServiceListener(),把VoiceSdkService中的VoiceSdkComAssist注册到application中，MusicActivity中可以通过getActivityToServiceListener
这个函数回调向VoiceSdkService发送消息。
2) 注册 VoiceSdkService到MusicActivity回调
public voidsetServiceToActivityListener(CommunicationAssist listener)
{
mServiceToActivityListener = listener;
}
这个是在MusicAcitivity中调用setServiceToActivityListener(),这样在VoiceSdkService中就可以通过getServiceToActivityListener()获得回调向MusciActivity发送消息。

if (data != null)
msg.setData(data);
if (obj != null)
msg.obj = obj;
mInComingHandler.sendMessage(msg);
}
}
@Override

super.onDestroy();
if(mOlamiVoiceRecognizer != null)

在VoiceSdkService.java中processServiceMessage(String message)用于处理onResult的回调数据。例如“我要听三国演义”返回如下数据：
{
"data": {
"asr": {
"result": "我要听三国演义",
"speech_status": 0,
"final": true,
"status": 0
},
"nli": [
{
"desc_obj": {
"result": "正在努力搜索中，请稍等",
"status": 0
},
"semantic": [
{
"app": "musiccontrol",
"input": "我要听三国演义",
"slots": [
{
"name": "songname",
"value": "三国演义"
}
],
"modifier": [
"play"
],
"customer": "58df512384ae11f0bb7b487e"
}
],
"type": "musiccontrol"
}
]
},
"status": "ok"
}
1）解析出nli中type类型是musiccontrol,这是语法返回app的类型，而这个在线听书的demo只关心musiccontrol这个app类型，其他的忽略。
2）用户说的话转成文字是在asr中的result中获取
3）在nli中的semantic中，input值是用户说的话，同asr中的result。
modifier代表返回的行为动作，此处可以看到是play就是要求播放，slots中的数据表示歌曲名称是三国演义。
那么动作是play，内容是歌曲名称是三国演义，在这个demo中调用
mBookUtil.searchBookAndPlay(songName,0,0);会先查询，查询到结果会再发播放消息要求播放，我要听三国演义这个流程就走完了。
说一下搜索听书的实现过程
public void searchBookInfo(StringbookName,final int index,final boolean isNeedPlay)
{
mBookName = bookName;
Map<String, String> param = new HashMap<String, String>();
param.put(DTransferConstants.SEARCH_KEY, bookName);
param.put(DTransferConstants.CATEGORY_ID, "" + 3);//此处3代表搜索的是听书
//param.put(DTransferConstants.PAGE, "" + mPageId);
param.put(DTransferConstants.SORT, "asc");//返回列表的排序是正序还是逆序
param.put(DTransferConstants.PAGE_SIZE, "" + PAGE_SIZE);//每页能返回多少个查询结果
mPage = (index/PAGE_SIZE)+1;//当前在第几页
mPlayerManager = XmPlayerManager.getInstance(mContext);//喜马拉雅初始化部分
mPlayerManager.init(mNotificationId, null);
mPlayerManager.addPlayerStatusListener(mPlayerStatusListener);
mPlayerManager.addAdsStatusListener(mAdsListener);
CommonRequest.getSearchedAlbums(param, newIDataCallBack<SearchAlbumList>()
{
@Override
public void onSuccess(SearchAlbumList object)
{
if (object != null && object.getAlbums() != null
&&object.getAlbums().size() != 0)
{
if (mSearchAlbumList == null)
{
mSearchAlbumList = object;
}
else
{
mSearchAlbumList.getAlbums().addAll(object.getAlbums());
}
//mTrackAdapter.notifyDataSetChanged();
Map<String, String> map =new HashMap<String, String>();
map.put(
DTransferConstants.ALBUM_ID,""+object.getAlbums().get(0).getId());
map.put(DTransferConstants.SORT, "asc");
map.put(DTransferConstants.PAGE, "" + mPage);
map.put(DTransferConstants.PAGE_SIZE, "" + PAGE_SIZE);
CommonRequest.getTracks(map,new IDataCallBack<TrackList>()
{
@Override
public voidonSuccess(TrackList object)
{
mTrackList =object;
mTotalCount =mTrackList.getTotalCount();
if(mTrackList.getTracks().size() <= 0)
return;
String str = "专辑："+mTrackList.getAlbumTitle()+
get(0).getTrackTitle().toString();
if(isNeedPlay)
{
mPosition =index % PAGE_SIZE;
mHandler.sendMessage(mHandler.obtainMessage MessageConst.CLIENT_ACTION_PLAY_BOOK_AFTER_SEARCH,
index %PAGE_SIZE,0));//此处mTrackList中已经查询出结果
//向VoiceSdkService发送消息进行播放
}
else
sendBookInfoToServer();
}
@Override
public void onError(intcode, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
}
@Override
public void onError(int code, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
