語音識別，語義理解一站式解決（android平臺&olami sdk）

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。

2.layout布局文件

layout_musicview.xml

TextView 有兩個，tv_name顯示聽書的名稱, tv_totoal_time顯示聽書的總時間。 
ProgressBar 實時刷新顯示聽書的進度

</RelativeLayout>

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bindservice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。

3.2MusicActivity

   private Handler mHandler;

3.4VoiceSdkService中onResult的回調處理

在VoiceSdkService.java中processServiceMessage(String message)用于處理onResult的回調數據。例如“我要聽三國演義”返回如下數據：

{

    "data": {

        "asr": {

            "result": "我要聽三國演義",

            "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<String, String> param = new HashMap<String, String>();

   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<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 = "專輯："+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。
