語音記賬demo：http://blog.csdn.net/ls0609/article/details/72765789
olami sdk實作了把錄音或者文字轉化為使用者可以了解的json字元串進而實作語義了解，使用者可以定義自己的語義，是不是很強大？本文講述怎麼自定義語義，以及如何解析自定義語義。
本文使用olami sdk做了一個線上聽書的demo，使用者隻需類似“我想聽***”就能實作聽書的線上查找并播放。用的是喜馬拉雅的線上聽書sdk.基于eclipse開發環境，libs目錄下jar和so檔案如下：
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 //上面這幾個都是喜馬拉雅需要的jar
libspeex.so //olami sdk 需要用到speex壓縮功能
libxmediaplayer.so // 喜馬拉雅so
libxmediaplayer_x.so // 喜馬拉雅so
概述：
VoiceSdkService中定義了OlamiVoiceRecognizer語音識别引擎，通過點選MusicActivity的開始button啟動錄音，錄音結果在VoiceSdkService中的onResult()回調中拿到識别的Json字元串，在processServiceMessage()函數中處理後找到要聽書的名稱，然後進入BookUtil進行搜尋，搜尋到結果後通知VoiceSdkService進行播放，并通知MusicActivity更新播放進度等資訊。

自定義MusicView比較簡單，代碼如下：
public class MusicView extends RelativeLayout{
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)
{//設定播放名稱
mTextViewName.setText(name);
}
public void setProgress(int progress)
{//設定播放進度
mProgressBar.setProgress(progress);
}
public void setTotalTime(String time)
{//設定播放總時間
mTextViewTotalTime.setText(time);
}
}
布局效果圖如下：
3.MusicActivity和VoiceSdkService通信
本文沒有用bind service的方式實作activity和service的消息通信。
MusicAcitity 和 VoiceSdkService中分别實作了一個CommunicationAssist的接口
public interface CommunicationAssist {
public void callBack(int what, int arg1, int arg2,Bundle data, Object obj);
}
然後把他們分别實作CommunicationAssist接口的變量注冊到OlamiApplication，這樣通過OlamiApplication實作了MusicAcitity 和 VoiceSdkService橋接。
3.1OlamiApplication
1) 注冊MusicActivity到VoiceSdkService的回調
public void setActivityToServiceListener(CommunicationAssist listener)
{
ActivityToServiceListener = listener;
}
這個是在VoiceSdkService中調用setActivityToServiceListener(),把VoiceSdkService中的VoiceSdkComAssist注冊到application中，MusicActivity中可以通過getActivityToServiceListener
這個函數回調向VoiceSdkService發送消息。
2) 注冊 VoiceSdkService到MusicActivity回調
public void setServiceToActivityListener(CommunicationAssist listener)
{
mServiceToActivityListener = listener;
}
這個是在MusicAcitivity中調用setServiceToActivityListener(),這樣在VoiceSdkService中就可以通過getServiceToActivityListener()獲得回調向MusciActivity發送消息。

}
private void sendMessageToActivity(int what, int arg1, int arg2, Bundle data, Object obj)
{
if(OlamiApplication.getInstance().getServiceToActivityListener() != null)
OlamiApplication.getInstance().getServiceToActivityListener().
callBack(what, arg1, arg2, data, obj);
}
private class VoiceSdkComAssist implements CommunicationAssist{
@Override
public void callBack(int what, int arg1, int arg2, Bundle data,Object obj) {
Message msg = Message.obtain(null, what);
msg.arg1 = arg1;
msg.arg2 = arg2;
if (data != null)
msg.setData(data);
if (obj != null)
msg.obj = obj;
mInComingHandler.sendMessage(msg);
}
}
@Override

3.4 VoiceSdkService中onResult的回調處理
在VoiceSdkService.java中processServiceMessage(String message)用于處理onResult的回調資料。例如“我要聽三國演義”傳回如下資料：
{
"data": {
"asr": {
"result": "我要聽三國演義",
"speech_status": ,
"final": true,
"status":
},
"nli": [
{
"desc_obj": {
"result": "正在努力搜尋中，請稍等",
"status":
},
"semantic": [
{
"app": "musiccontrol",
"input": "我要聽三國演義",
"slots": [
{
"name": "songname",
"value": "三國演義" }
],
"modifier": [
"play"
],
"customer": "58df512384ae11f0bb7b487e"
}
],
"type": "musiccontrol"
}
]
},
"status": "ok"
}
1）解析出nli中type類型是musiccontrol,這是文法傳回app的類型，而這個線上聽書的demo隻關心musiccontrol這 個app類型，其他的忽略。
2）使用者說的話轉成文字是在asr中的result中擷取
3）在nli中的semantic中，input值是使用者說的話，同asr中的result。
modifier代表傳回的行為動作，此處可以看到是play就是要求播放，slots中的資料表示歌曲名稱是三國演義。
那麼動作是play，内容是歌曲名稱是三國演義，在這個demo中調用
mBookUtil.searchBookAndPlay(songName,0,0);會先查詢，查詢到結果會再發播放消息要求播放，我要聽三國演義這個流程就走完了。
4.BookUtil
說一下搜尋聽書的實作過程
public void searchBookInfo(String bookName,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, "" + );//此處3代表搜尋的是聽書
//param.put(DTransferConstants.PAGE, "" + mPageId);
param.put(DTransferConstants.SORT, "asc");//傳回清單的排序是正序還是逆序
param.put(DTransferConstants.PAGE_SIZE, "" + PAGE_SIZE);//每頁能傳回多少個查詢結果
mPage = (index/PAGE_SIZE)+;//目前在第幾頁
mPlayerManager = XmPlayerManager.getInstance(mContext);//喜馬拉雅初始化部分
mPlayerManager.init(mNotificationId, null);
mPlayerManager.addPlayerStatusListener(mPlayerStatusListener);
mPlayerManager.addAdsStatusListener(mAdsListener);
CommonRequest.getSearchedAlbums(param, new IDataCallBack<SearchAlbumList>()
{
@Override
public void onSuccess(SearchAlbumList object)
{
if (object != null && object.getAlbums() != null
&& object.getAlbums().size() != )
{
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().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 void onSuccess(TrackList object)
{
mTrackList = object;
mTotalCount = mTrackList.getTotalCount();
if(mTrackList.getTracks().size() <= )
return;
String str = "專輯："+mTrackList.getAlbumTitle()+
get().getTrackTitle().toString();
if(isNeedPlay)
{
mPosition = index % PAGE_SIZE;
mHandler.sendMessage(mHandler.obtainMessage(
MessageConst.CLIENT_ACTION_PLAY_BOOK_AFTER_SEARCH,
index % PAGE_SIZE,));//此處mTrackList中已經查詢出結果
//向VoiceSdkService發送消息進行播放
}
else
sendBookInfoToServer();
}
@Override
public void onError(int code, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
}
@Override
public void onError(int code, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
5.demo中支援的說法
我想聽西遊記
我要聽西遊記
播放西遊記
聽西遊記
我想聽西遊記這本書
上一首
上一回
下一首
下一回
暫停/暫停播放
繼續/繼續播放
聲音大一點
聲音小一點
關閉/關閉播放
用的是喜馬拉雅測試賬号，隻支援聽書的功能，查找歌曲的結果傳回為空。
