用olami sdk語音識別語義理解做在線聽書
olamisdk實現了把錄音或者文字轉化為用戶可以理解的json字符串，本文使用olami sdk做了一個在線聽書的demo，用的是喜馬拉雅的在線聽書sdk.基于eclipse開發環境，libs目錄下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語音識別引擎，通過點擊MusicActivity的開始button啟動錄音，錄音結果在VoiceSdkService中的onResult()回調中拿到識別的Json字符串，在processServiceMessage()函數中處理后找到要聽書的名稱，然后進入BookUtil進行搜索，搜索到結果后通知VoiceSdkService進行播放，并通知MusicActivity更新播放進度等信息。
1.AndroidManifest.xml配置

2.layout布局文件

TextView有兩個，tv_name顯示聽書的名稱, tv_totoal_time顯示聽書的總時間。

自定義MusicView比較簡單，代碼如下：
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)
{//設置播放名稱
mTextViewName.setText(name);
}
public void setProgress(int progress)
{//設置播放進度
mProgressBar.setProgress(progress);
}
public void setTotalTime(String time)
{//設置播放總時間
mTextViewTotalTime.setText(time);
}
}
布局效果圖如下：
3.MusicActivity和VoiceSdkService通信
本文沒有用bind
service的方式實現activity和service的消息通信。
MusicAcitity和VoiceSdkService中分別實現了一個CommunicationAssist的接口
public interface CommunicationAssist {
public void callBack(int what, int arg1, int arg2,Bundle data, Objectobj);
}
然后把他們分別實現CommunicationAssist接口的變量注冊到OlamiApplication，這樣通過OlamiApplication實現了MusicAcitity和VoiceSdkService橋接。
3.1OlamiApplication
1)注冊MusicActivity到VoiceSdkService的回調
public voidsetActivityToServiceListener(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 voidsetServiceToActivityListener(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。

"speech_status":0,
"final":true,
"status":0
},
"nli": [
{
"desc_obj": {
"result":"正在努力搜索中，請稍等",
"status":0
},
"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,這是語法返回app的類型，而這個在線聽書的demo只關心musiccontrol這個app類型，其他的忽略。
2）用戶說的話轉成文字是在asr中的result中獲取
3）在nli中的semantic中，input值是用戶說的話，同asr中的result。
modifier代表返回的行為動作，此處可以看到是play就是要求播放，slots中的數據表示歌曲名稱是三國演義。
那么動作是play，內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
說一下搜索聽書的實現過程
public void searchBookInfo(StringbookName,final int index,final boolean isNeedPlay)
{
mBookName = bookName;
Map param = new HashMap();
param.put(DTransferConstants.SEARCH_KEY, bookName);
param.put(DTransferConstants.CATEGORY_ID, "" + 3);//此處3代表搜索的是聽書
//param.put(DTransferConstants.PAGE, "" + mPageId);
param.put(DTransferConstants.SORT, "asc");//返回列表的排序是正序還是逆序
param.put(DTransferConstants.PAGE_SIZE, "" + PAGE_SIZE);//每頁能返回多少個查詢結果
mPage = (index/PAGE_SIZE)+1;//當前在第幾頁
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, newIDataCallBack()
{
@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 map =new HashMap();
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()
{
@Override
public voidonSuccess(TrackList object)
{
mTrackList =object;
mTotalCount =mTrackList.getTotalCount();
if(mTrackList.getTracks().size() <= 0)
return;
String str = "專輯："+mTrackList.getAlbumTitle()+
get(0).getTrackTitle().toString();
if(isNeedPlay)
{
mPosition =index % PAGE_SIZE;
mHandler.sendMessage(mHandler.obtainMessageMessageConst.CLIENT_ACTION_PLAY_BOOK_AFTER_SEARCH,
index %PAGE_SIZE,0));//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(intcode, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
}
@Override
public void onError(int code, String message)
{
Log.i("ppp","error: "+message);
sendBookInfoToServer();
}
});
}
5.demo中支持的說法
我想聽西游記
我要聽西游記
播放西游記
聽西游記
我想聽西游記這本書
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號，只支持聽書的功能，查找歌曲的結果返回為空。
