音频输入和输出（Android代码）

问题描述：

如何在我的android代码中更改音频输入和输出语言？我应该编辑这段代码来改变音频输入输出语言吗？ {我想一个变量设置为恩语音语言英语或变量设置为TR选择土耳其，如果这可能吗？}音频输入和输出（Android代码）

public Intent getRecognizeIntent() 
    { 
     Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
     intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
       RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
     intent.putExtra(RecognizerIntent.EXTRA_PROMPT, prompt); 
     intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 100); 
     return intent; 
    }

或者，这帮助我改变？ - > EXTRA_LANGUAGE_PREFERENCE

答

这应该工作在大多数情况下：

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");

或

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, Locale.getDefault());

当你选择你想要的语言环境，并通过它的toString（），以EXTRA_LANGUAGE_PREFERENCE

然而，要正确，你应该尝试做一次语言检查，并观察返回的“声音”。手动或自动选择所需的“语音”字符串，然后将其用于RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE值。

下面是一些代码来执行的语言检查：

public static void getLanguageDetails(Context context, 
     OnLanguageDetailsListener andThen) 
{ 
    Intent detailsIntent = new Intent(
      RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS); 
    LanguageDetailsChecker checker = new LanguageDetailsChecker(andThen); 
    context.sendOrderedBroadcast(detailsIntent, null, checker, null, 
      Activity.RESULT_OK, null, null); 
}

其中LanguageDetailsChecker是这样的：

public class LanguageDetailsChecker extends BroadcastReceiver 
{ 
    private List<String> supportedLanguages; 

    private String languagePreference; 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     Bundle results = getResultExtras(true); 
     if (results.containsKey(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE)) 
     { 
      languagePreference = 
        results.getString(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE); 
     } 
     if (results.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES)) 
     { 
      supportedLanguages = 
        results.getStringArrayList(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES); 
     } 
     } 
}

答

我设置RecognizerIntent语言土耳其这样的：

language = "tr-TR"; 
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, language); 
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, language); 
intent.putExtra(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES, language); 
intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE,language); 
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, language); 
intent.putExtra(RecognizerIntent.EXTRA_RESULTS, language); 
startActivityForResult(intent, REQUEST_CODE);

答

如果要指定一个语言识别你需要把：

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, language);

其中language与区域设置格式的字符串。
