语音合成和识别接口

第一步：导入jar包
再libs文件夹，导入Msc.jar和Sunflower.jar，还有so包（这个要看手机是什么芯片）。

第二步：代码
MainActivity:

package com.example.speechtest2;import android.support.v7.app.ActionBarActivity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.annotation.SuppressLint;import android.app.Activity;import android.app.AlertDialog;import android.content.Context;import android.content.DialogInterface;import android.content.Intent;import android.content.SharedPreferences;import android.os.Bundle;import android.os.Environment;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.widget.Button;import android.widget.EditText;import android.widget.RadioGroup;import android.widget.TextView;import android.widget.RadioGroup.OnCheckedChangeListener;import android.widget.Toast;import com.iflytek.cloud.ErrorCode;import com.iflytek.cloud.InitListener;import com.iflytek.cloud.RecognizerListener;import com.iflytek.cloud.RecognizerResult;import com.iflytek.cloud.SpeechConstant;import com.iflytek.cloud.SpeechError;import com.iflytek.cloud.SpeechRecognizer;import com.iflytek.cloud.SpeechSynthesizer;import com.iflytek.cloud.SpeechUtility;import com.iflytek.cloud.SynthesizerListener;import com.iflytek.thirdparty.t;public class MainActivity extends ActionBarActivity{    //private static String TAG = TtsDemo.class.getSimpleName();    private TextView hello;    private Button btnButton;    // 语音合成对象    private SpeechSynthesizer mTts;    // 默认发音人    private String voicer = "xiaoyan";    private String[] mCloudVoicersEntries;    private String[] mCloudVoicersValue ;

       setContentView(R.layout.activity_main);        hello = (TextView)findViewById(R.id.hello);        btnButton = (Button)findViewById(R.id.btn);        btnButton.setOnClickListener(t);        //认证接口        SpeechUtility.createUtility(getApplicationContext(), SpeechConstant.APPID+"=xxxx,usr=xxxx,pwd=xxxx");

       //语音识别        mIat = SpeechRecognizer.createRecognizer(getApplicationContext(), null);        //支持的应用领域,iat:短信和日常用语;video:视频;poi:地图; music:音乐        mIat.setParameter(SpeechConstant.DOMAIN, "iat");

   /**     * 合成回调监听。     */    private SynthesizerListener mTtsListener = new SynthesizerListener() {        @Override        public void onSpeakBegin() {            showTip("开始播放");        }        @Override        public void onSpeakPaused() {            showTip("暂停播放");

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.speechtest2.MainActivity" >    <TextView        android:id="@+id/hello"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world" />    <Button         android:id="@+id/btn"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="重新再讲"        android:layout_below="@+id/hello"        /></RelativeLayout>

AndroidManifest.xml
把以下代码放在后面

    <uses-permission android:name="android.permission.RECORD_AUDIO" />    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />    <uses-permission android:name="android.permission.READ_CONTACTS" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.WRITE_SETTINGS" />    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

语音识别返回的是json，如：

{"sn":1,"ls":false,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"有"}],{"bg":0,"cw":[{"sc":0.00."w":"搞"}],{"bg":0,"cw":[{"sc":0.00,"w":"啊"}]}]}{"sn":2,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"。"}]}]}
