我在Android上尝试使用文本到语音的概念证明但没有成功。关于这一点的任何建议,在这里我将如何进行:
这发生在片段中:
public class PhotoDetailsFragment extends Fragment implements TextToSpeech.OnInitListener{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initialising text to speech to speak the common names
tts = new TextToSpeech(getActivity(), this);
}
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "This Language is not supported");
} else {
speakOut();
}
} else {
Log.e("TTS", "Initilization Failed!");
}
}
private void speakOut() {
System.out.println("Speaking");
tts.speak("Animal", TextToSpeech.QUEUE_FLUSH, null);
}
..................
}
答案 0 :(得分:0)
我使用tts.setLanguage(Locale.US)运气不好。这是我使用的代码:
if (mSpeaker.isLanguageAvailable(Locale.UK) == TextToSpeech.LANG_AVAILABLE) {
Log.i(TAG, "Whee! We have UK English");
mSpeaker.setLanguage(Locale.UK);
} else if (mSpeaker.isLanguageAvailable(Locale.US) == TextToSpeech.LANG_AVAILABLE) {
Log.i(TAG, "We have US English");
mSpeaker.setLanguage(Locale.US);
} else {
Log.i(TAG, "Using Speech engine default Locale");
}
当此代码在我的Samsung S4手机上运行时,它使用默认语言环境而不是Locale.UK或Locale.US。
尝试删除tts.setLanguage(Locale.US)和结果测试。
另一种可能性是必须从UI线程调用tts.speak()(我只是猜测 - 我不确定)。我注意到许多Android API没有指定必须从UI线程调用的内容。您可以尝试以下代码而不是调用speakOut():
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
speakOut();
}
});
