Android SpeechRecognizer存在问题。它在Android版本2.3.5上完全适用于英语(en-GB)和德语(de-DE),但在版本4.0.3中它始终用英语识别语音,尽管指定的语言是德语。
这是我传递给SpeechRecognizer的Intent。
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, language);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
mContext.getPackageName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
mRecognizer.startListening(intent);
我确信变量总是好的(当我想要德语等时de-DE。)。
我也尝试添加:
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, language);
但它也不起作用。
我也确信SpeechRecognizer支持德语。我正在使用此BroadcastReceiver获取可用语言列表。
public class AndroidAvailableLanguagesChecker extends BroadcastReceiver {
private List<String> supportedLanguages;
public AndroidAvailableLanguagesChecker() {
supportedLanguages = new ArrayList<String>();
}
@Override
public void onReceive(Context context, Intent intent) {
Bundle results = getResultExtras(true);
if (results.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES)) {
supportedLanguages = results
.getStringArrayList(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);
}
}
public List<String> getSupportedLanguages() {
return supportedLanguages;
}
}
// using broadcast receiver
Intent detailsIntent = new Intent(
RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
mChecker = new AndroidAvailableLanguagesChecker();
context.sendOrderedBroadcast(detailsIntent, null, mChecker, null,
Activity.RESULT_OK, null, null);
有人知道为什么这不起作用吗?
提前致谢!
答案 0 :(得分:0)
这只是一个假设,而不是现在的测试,但也许语言必须是“de_DE”而不是“de-DE”,请试试....
