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。

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: 3.MusicActivity和VoiceSdkService通信本文没有用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。 3.1OlamiApplication1)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。 3.2MusicActivitypublic class MusicActivity extends Activity{ private Handler mHandler;

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: 3.MusicActivity和VoiceSdkService通信本文没有用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。 3.1OlamiApplication1)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。 3.2MusicActivitypublic class MusicActivity extends Activity{ private Handler mHandler;

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: 3.MusicActivity和VoiceSdkService通信本文没有用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。 3.1OlamiApplication1)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。 3.2MusicActivitypublic class MusicActivity extends Activity{ private Handler mHandler;

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: 3.MusicActivity和VoiceSdkService通信本文没有用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。 3.1OlamiApplication1)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。 3.2MusicActivitypublic class MusicActivity extends Activity{ private Handler mHandler;

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。
