Android中TextToSpeech的简单使用

android也可以实现把输入的文字朗读出来，使用到的是TextToSpeech，不过目前只支持5种语言：English、 French 、 German 、 Italian 和 Spanish。（真遗憾，没有Chinese），对android系统要求为android
1.6(API8)以上：

public class SpeechTestActivity extends Activity {

/**TextToSpeech对象*/

private TextToSpeech mText2Speech;

/**确定按钮*/

private Button mBtn;

/**文本输入框*/

private EditText mEdt;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

findViewsById();

initListeners();

mBtn = (Button) findViewById(R.id.test_btn);

mEdt = (EditText) findViewById(R.id.test_edt);

mBtn.setEnabled(false);

}

private void initListeners() {

mText2Speech = new TextToSpeech(this, new OnInitListener() {

@Override

public void onInit(int status) {

if (status == TextToSpeech.SUCCESS) {/**如果装载TTS成功*/

int result = mText2Speech.setLanguage(Locale.ENGLISH);/**有Locale.CHINESE,但是不支持中文*/

if (result == TextToSpeech.LANG_MISSING_DATA/**表示语言的数据丢失。*/

|| result == TextToSpeech.LANG_NOT_SUPPORTED) {/**语言不支持*/

Toast.makeText(SpeechTestActivity.this, "我说不出口", Toast.LENGTH_SHORT).show();

} else {

mBtn.setEnabled(true);

mText2Speech.speak("I miss you", TextToSpeech.QUEUE_FLUSH,

null);

}

}

}

});

mBtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

mText2Speech.speak(mEdt.getText().toString(),

TextToSpeech.QUEUE_FLUSH, null);

}

});

}

private void findViewsById() {

mBtn = (Button) findViewById(R.id.test_btn);

mEdt = (EditText) findViewById(R.id.test_edt);

}

@Override

protected void onDestroy() {

if (mText2Speech != null) {

mText2Speech.stop();

mText2Speech.shutdown();

}

super.onDestroy();

}

}
