Question

我已经浏览了与此主题相关的几乎所有链接，但未找到任何合适的答案。我正在尝试构建一个基本的文本到语音应用程序。它在模拟器上完美运行。但是当我在手机上运行时，它显示不支持的语言。我想这与语言环境有关。我手机中设置的默认语言环境为en_US 我的代码如下：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    tts = new TextToSpeech(this, this);
    btnSpeak = (Button) findViewById(R.id.btnSpeak);
    txtText = (EditText) findViewById(R.id.txtText);
    btnSpeak.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            // Method yet to be defined
            speakOut();
        }

    });
}

public void onInit(int status) {
    // TODO Auto-generated method stub
    // TTS is successfully initialized
    if (status == TextToSpeech.SUCCESS) {
        // Setting speech language
        // System.out.println(Locale.getAvailableLocales());
        int result = tts.setLanguage(Locale.ENGLISH);
        // int result = tts.setLanguage(Locale.getDefault());
        // If your device doesn't support language you set above
        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            // Cook simple toast message with message
            Toast.makeText(this, "Language not supported",
                    Toast.LENGTH_LONG).show();
            Log.e("TTS", "Language is not supported");

        } else {
            btnSpeak.setEnabled(true);
        }
        // TTS is not initialized properly
    } else {
        Toast.makeText(this, "TTS Initilization Failed", Toast.LENGTH_LONG)
                .show();
        Log.e("TTS", "Initilization Failed");
    }
}

private void speakOut() {
    // Get the text typed
    String text = txtText.getText().toString();
    // If no text is typed, tts will read out 'You haven't typed text'
    // else it reads out the text you typed
    if (text.length() == 0) {
        tts.speak("You haven't typed text", TextToSpeech.QUEUE_FLUSH, null);
    } else {
        tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
    }

}

public void onDestroy() {
    // Don't forget to shutdown!
    if (tts != null) {
        tts.stop();
        tts.shutdown();
    }
    super.onDestroy();
}

即使我使用int result = tts.setLanguage(Locale.getDefault());代替Locale.ENGLISH，也会显示相同语言不支持的消息

LOGCAT错误：

02-26 16:24:57.492: I/TextToSpeech.java(23356): initTts() successfully bound to service
02-26 16:24:58.015: E/TTS(23356): Language is not supported

我在手机上运行 - 三星Galaxy-Y（GT-S5360）与Android版本2.3.6

自己找到了解决方案。问题是android默认tts引擎上可用的语言环境与我手机上的语言环境不匹配我安装了另一个tts引擎，它可以很好地完成它。

文本到语音在模拟器上有效，但在手机上无效
