文字转语音-不说话

Question

我对一个会从编辑文本中说出单词的代码感到困惑，我使用的代码没有说出来，但它正确获取了值，字符数等。

我使用的代码是..

 public class AndroidTextToSpeechActivity extends Activity implements
    TextToSpeech.OnInitListener {
/** Called when the activity is first created. */

private TextToSpeech tts;
private Button btnSpeak;
private EditText txtText;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    System.out.println("Entered to the Activity");
    tts = new TextToSpeech(this, this);

    btnSpeak = (Button) findViewById(R.id.btnSpeak);

    txtText = (EditText) findViewById(R.id.txtText);

    // button on click event
    btnSpeak.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            speakOut();
        }

    });
}

@Override
public void onDestroy() {
    // Don't forget to shutdown!
    if (tts != null) {
        System.out.println("Entered  to OnDestroy");
        tts.stop();
        tts.shutdown();
    }
    super.onDestroy();
}

@Override
public void onInit(int status) {
    // TODO Auto-generated method stub

    System.out.println("Enterd init Function");
    if (status == TextToSpeech.SUCCESS) {

        int result = tts.setLanguage(Locale.ENGLISH);

        // tts.setPitch(5); // set pitch level

        // tts.setSpeechRate(2); // set speech speed rate

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "Language is not supported");
        } else {
            btnSpeak.setEnabled(true);
            speakOut();
        }

    } else {
        Log.e("TTS", "Initilization Failed");
    }

}

private void speakOut() {
     System.out.println("Entered Speakout");
    String text = txtText.getText().toString();

    tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}

它返回不支持languagge的消息。我该如何纠正

试试这个可能对您有帮助。

我认为您的设备中未安装语音合成器，因此请使用它们。如果未安装，它将重定向到Google Play进行安装。

 public void onInit(int status) {
    if (status == TextToSpeech.SUCCESS) {
        int result = talker.setLanguage(Locale.US);
        if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "This Language is not supported");
            Intent installIntent = new Intent();
            installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);
        } else {
            btnSpeak.setEnabled(true);
            speakOut();
        }
    } else {
        Log.e("TTS", "Initilization Failed!");
    }
}
