Android文字转语音TTS离线程序

android原生rom，本自带tts语音，在这基础上可以直接调用使用即可。源码如下。

public class TTSdemo extends Activity implements OnInitListener{

/** Called when the activity is first created. */private EditText inputText = null;private Button speakBtn = null;/** * default state ： CHECK_VOICE_DATA_FAIL = 0; */private static final int REQ_TTS_STATUS_CHECK = 0;private static final String TAG = "TTS Demo";private TextToSpeech mTts;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);try {//"这里注意，如果本机tts没有安装，这里就会抓获到异常的。tts使用的时候也要注意非空验证"// 检查TTS数据是否已经安装并且可用Intent checkIntent = new Intent();checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);// 检查TTS状态PackageManager pm = getPackageManager();ResolveInfo resolveInfo = pm.resolveActivity( checkIntent, PackageManager.MATCH_DEFAULT_ONLY );if( resolveInfo == null ) {// Not able to find the activity which should be started for this intentLog.e("----resolveInfo--------", "" + " Not able to find the activity which should be started for this intent");} else {startActivityForResult(checkIntent, REQ_TTS_STATUS_CHECK);}} catch (ActivityNotFoundException e) {Log.e(TAG, "Oops! The function is not available in your device." + e.fillInStackTrace()); }inputText = (EditText) findViewById(R.id.inputText);speakBtn = (Button) findViewById(R.id.speakBtn);inputText.setText("This is an example of speech synthesis.");speakBtn.setOnClickListener(new OnClickListener() {public void onClick(View v) {// TODO Auto-generated method stubmTts.speak(inputText.getText().toString(), TextToSpeech.QUEUE_ADD, null);// 朗读输入框里的内容}});}

// 实现TTS初始化接口@Overridepublic void onInit(int status) {// TODO Auto-generated method stub// TTS Engine初始化完成if (status == TextToSpeech.SUCCESS) {int result = mTts.setLanguage(Locale.US);// 设置发音语言if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED)// 判断语言是否可用{Log.v(TAG, "Language is not available");speakBtn.setEnabled(false);} else {mTts.speak("This is an example of speech synthesis.", TextToSpeech.QUEUE_ADD, null);speakBtn.setEnabled(true);}}}protected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == REQ_TTS_STATUS_CHECK) {switch (resultCode) {case TextToSpeech.Engine.CHECK_VOICE_DATA_PASS:// 这个返回结果表明TTS Engine可以用{mTts = new TextToSpeech(this, this);Log.v(TAG, "TTS Engine is installed!");}break;case TextToSpeech.Engine.CHECK_VOICE_DATA_BAD_DATA:// 需要的语音数据已损坏case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_DATA:// 缺少需要语言的语音数据case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_VOLUME:// 缺少需要语言的发音数据{// 这三种情况都表明数据有错,重新下载安装需要的数据Log.v(TAG, "Need language stuff:" + resultCode);Intent dataIntent = new Intent();dataIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);startActivity(dataIntent);}break;case TextToSpeech.Engine.CHECK_VOICE_DATA_FAIL:// 检查失败default:Log.v(TAG, "Got a failure. TTS apparently not available");break;}} else {// 其他Intent返回的结果}}@Overrideprotected void onPause() {// TODO Auto-generated method stubsuper.onPause();if (mTts != null)// activity暂停时也停止TTS{mTts.stop();}}@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();// 释放TTS的资源if (mTts != null)mTts.shutdown();}

以上源码粘贴进入项目就没有问题了。但是这只是英文。而且对于手机的tts依赖很高，如果手机没有装tts，那么这个程序时不起作用的，无法发音。

所有，第二种，从网络寻找离线“语音合成”，大家都在说什么讯飞XX ，百度XX等等，百度不知道。至少讯飞亲自测试了。就是一个收费的垃圾？？

根本没有免费，而且还是在线的。如下。

于是继续找寻，暂时找到了一个离线的 ‘语音合成’demo，支持中文语音，但是发现一个问题，对于单词都读成一个个字母了。暂时没有调整。项目如下。

诸如此类的大量文章，手机如果没有tts，都是无法运行的（http://blog.csdn.net/ichliebephone/article/details/6373184#java）

我找到的，离线语音包的demo现在分享出来，共同研究。下载地址：http://download.csdn.net/detail/flyingsir_zw/9453049

后续会继续更新。
