指的是 泰德·霍普的在此<一个答案href="http://stackoverflow.com/questions/9713594/how-can-i-save-my-android-tts-output-in-a-wav-file">post ：
最重要的方法是<一个href="http://developer.android.com/reference/android/speech/tts/TextToSpeech.html#synthesizeToFile%28java.lang.String,%20java.util.HashMap%3Cjava.lang.String,%20java.lang.String%3E,%20java.lang.String%29"相对=nofollow> synthesizeToFile 。它会写音频到您指定的设备上的文件。然后，您可以播放该文件用MediaPlayer的，也可以用ADB命令行工具，使用该命令关闭设备拉出到您的开发系统
编辑：
试试这个code，然后检查路径 SD卡/ 如果它包含文件： test.wav
的HashMap＆LT;字符串，字符串＆GT; myHashRender =新的HashMap（）;
字符串textToConvert =这是一个演示用于保存WAV文件;
字符串目的地文件=/sdcard/test.wav;
myHashRender.put（TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID，textToConvert）;
mTts.synthesizeToFile（textToConvert，myHashRender，目的地文件）;
编辑2：
如果你试图波形文件保存到内存中（而不是 / SD卡/ 文件夹），那么实现这一目标的唯一方法是创建一个可写
在内部存储器这样的目录：
context.getDir（soundfiles，Context.MODE_WORLD_WRITEABLE）;
然后写入该目录。
修改3：
考虑看看到code之后，你刚刚的一些问题与创建目录和文件：在code应该是这样的：
speakTextTxt =世界，你好;
HashMap的＆LT;字符串，字符串＆GT; myHashRender =新的HashMap＆LT;字符串，字符串＆GT;（）;
myHashRender.put（TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID，speakTextTxt）;
字符串exStoragePath = Environment.getExternalStorageDirectory（）getAbsolutePath（）。
Log.d（MainActivity，exStoragePath：+ exStoragePath）;
文件appTmpPath =新的文件（exStoragePath +/声音/）;
布尔isDirectoryCreated = appTmpPath.mkdirs（）;
Log.d（MainActivity，目录+ appTmpPath +创建+ isDirectoryCreated）;
字符串tempFilename =tmpaudio.wav;
tempDestFile = appTmpPath.getAbsolutePath（）+文件分割符+ tempFilename;
Log.d（MainActivity，tempDestFile：+ tempDestFile）;
新MySpeech（speakTextTxt）;
我已经在Android模拟器测试它，它工作得很好，但你需要指定使用设备管理器，编辑eumlator你的模拟器轮空的SD卡的大小，并指定你的SD卡的大小：例如512 MB。然后你会发现在该路径的wav文件： MNT / SD卡/声音/ tmpaudio.wav
测试它，只需打开 DDMS透视图，文件浏览器，然后将文件导出到您的计算机。
I am using the following code to store Text to Speech output as wav file in my application. I am not sure where is the error, can you please take a look into that and suggest me?
public class MainActivity extends Activity {
Button store, play;
EditText input;
String speakTextTxt;
TextToSpeech mTts;
HashMap<String, String> myHashRender = new HashMap<String, String>();
String tempDestFile ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
store = (Button) findViewById(R.id.button1);
play = (Button) findViewById(R.id.button2);
input = (EditText) findViewById(R.id.editText1);
store.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
speakTextTxt = "Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world";
HashMap<String, String> myHashRender = new HashMap<String, String>();
myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, speakTextTxt);
String exStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
File appTmpPath = new File(exStoragePath + "/sounds/");
appTmpPath.mkdirs();
String tempFilename = "hello.mp3";
tempDestFile = appTmpPath.getAbsolutePath() + "/" + tempFilename;
new MySpeech(speakTextTxt);
}
});
}
class MySpeech implements OnInitListener
{
String tts;
public MySpeech(String tts)
{
this.tts = tts;
mTts = new TextToSpeech(MainActivity.this, this);
}
@Override
public void onInit(int status)
{
Log.v("log", "initi");
int i = mTts.synthesizeToFile(speakTextTxt, myHashRender, tempDestFile);
if(i == TextToSpeech.SUCCESS)
{
Toast toast = Toast.makeText(MainActivity.this, "Saved "+i,
Toast.LENGTH_SHORT);
toast.show();
}
System.out.println("Result : " + i);
}
}
}
referring to the answer of Ted Hopp in this post :
The important method is synthesizeToFile. It will write the audio to a file on the device that you specify. You can then play that file with a MediaPlayer or you can pull it off the device onto your development system with the adb command-line tool using the command
EDIT :
try this code , and then check the path sdcard/ if it contains the file : test.wav
HashMap<String, String> myHashRender = new HashMap();
String textToConvert = "this is a demo for saving a WAV file";
String destinationFileName = "/sdcard/test.wav";
myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, textToConvert);
mTts.synthesizeToFile(textToConvert, myHashRender, destinationFileName);
EDIT 2 :
and if you are trying to save the wave file to the internal memory ( not the /sdcard/folder) , then the only way to achieve this is to create a world writable
directory in the internal memory like this:
context.getDir("soundfiles", Context.MODE_WORLD_WRITEABLE);
And then write to this dir.
EDIT 3 :
after taking a look into your code , you've just some problems with creating directories and files : the code should be like this :
speakTextTxt = "Hello world";
HashMap<String, String> myHashRender = new HashMap<String, String>();
myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, speakTextTxt);
String exStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
Log.d("MainActivity", "exStoragePath : "+exStoragePath);
File appTmpPath = new File(exStoragePath + "/sounds/");
boolean isDirectoryCreated = appTmpPath.mkdirs();
Log.d("MainActivity", "directory "+appTmpPath+" is created : "+isDirectoryCreated);
String tempFilename = "tmpaudio.wav";
tempDestFile = appTmpPath.getAbsolutePath() + File.separator + tempFilename;
Log.d("MainActivity", "tempDestFile : "+tempDestFile);
new MySpeech(speakTextTxt);
i've tested it on android emulator , and it works fine , but you need to specify the size of the sdCard of your emulator bye using device manager, edit eumlator, and specify the size of your sdcard : example 512 Mb. and then you will find the wav file in the path : mnt/sdcard/sounds/tmpaudio.wav
to test it , just open the DDMS perspective, File Explorer, and then export the file to your PC .
