本文介绍了一个基于Android平台实现的文本转语音(Text To Speech, TTS)应用案例。该应用通过使用TTS引擎来实现对指定文本内容的朗读功能，并详细展示了如何初始化TTS引擎、设置语音参数以及触发朗读过程的技术细节。

private Button speechBtn; // 按钮控制开始朗读
private TextView speechTxt; // 需要朗读的内容
private TextToSpeech textToSpeech; // TTS对象
 
@Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
speechBtn = (Button) findViewById(R.id.speechBtn);
  speechTxt = (TextView) findViewById(R.id.speechTxt);
 
textToSpeech = new TextToSpeech(MainActivity.this,
    new TextToSpeech.OnInitListener() {
     
     @Override
     public void onInit(int status) {
      // TODO Auto-generated method stub
      if (status == TextToSpeech.SUCCESS) {
       int result = textToSpeech.setLanguage(Locale.US);
       if (result == TextToSpeech.LANG_MISSING_DATA
         || result == TextToSpeech.LANG_NOT_SUPPORTED) {
        Toast.makeText(MainActivity.this, "数据丢失或不支持",
          Toast.LENGTH_SHORT).show();
       }
      }
     }
    });
speechBtn.setOnClickListener(new OnClickListener() {
@Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    if (textToSpeech != null && !textToSpeech.isSpeaking()) {
     textToSpeech.setPitch(1.5f);// 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规
     textToSpeech.speak(speechTxt.getText().toString(),
       TextToSpeech.QUEUE_FLUSH, null);
    }
   }
  });
}
@Override
 protected void onStop() {
  super.onStop();
  textToSpeech.stop(); // 不管是否正在朗读TTS都被打断
  textToSpeech.shutdown(); // 关闭，释放资源
 }
