Android中texttospeech如何使用

在Android中使用TextToSpeech需要以下步骤：

1. 在AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> 

2. 在Activity或Fragment中初始化TextToSpeech对象：

private TextToSpeech textToSpeech; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() { @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { int result = textToSpeech.setLanguage(Locale.US); // 设置语言为英语 if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) { Log.e("TTS", "Language not supported"); } } else { Log.e("TTS", "Initialization failed"); } } }); } 

3. 调用TextToSpeech对象的speak方法进行文本转语音：

textToSpeech.speak("Hello, World!", TextToSpeech.QUEUE_FLUSH, null); 

注意，在使用完TextToSpeech后要记得在Activity或Fragment的onDestroy方法中释放TextToSpeech资源：

@Override protected void onDestroy() { if (textToSpeech != null) { textToSpeech.stop(); textToSpeech.shutdown(); } super.onDestroy(); } 

这样就可以在Android中使用TextToSpeech进行文本转语音了。
