How to set the language in speech recognition on android?
提问by Mr.Me
I've been working on speech Recognition API in android and found out that the speech results vary allot when the language settings are changed , is there a way to set it programmatically ? or is there an intent to lunch the speech language settings screen ? or what else ? note: I tried to use this intent extra:
我一直在研究 android 中的语音识别 API，发现更改语言设置时语音结果会有所不同，有没有办法以编程方式设置它？或者是否打算在语音语言设置屏幕上吃午饭？或者还有什么？注意：我试图额外使用这个意图：
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en-US");
but it was ineffective
但它是无效的

As pargat says, this will do it:
正如 pargat 所说，这会做到：
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
Also, your app can query for the list of supported languages by sending a RecognizerIntent.ACTION_GET_LANGUAGE_DETAILSordered broadcast like so:
此外，您的应用程序可以通过发送RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS有序广播来查询支持的语言列表，如下所示：
Intent detailsIntent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
sendOrderedBroadcast(
detailsIntent, null, new LanguageDetailsChecker(), null, Activity.RESULT_OK, null, null);
where LanguageDetailsChecker is something like this:
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);
}
}
}

This will work:
这将起作用：
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en_US");
You have to use "en_US" instead of "en-US". The former is the right format of Java locale tag.
您必须使用“en_US”而不是“en-US”。前者是 Java 语言环境标记的正确格式。
It is suggested that you use
建议您使用
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.US.toString());
to avoid remembering such detail.
避免记住这样的细节。

Have you tried this:
你有没有试过这个：

I finally got my app to restrict voice recognition results to a specified language input (handing it, e.g., "ja" for Japanese or "fr" for French) by adding all 3 of the following extras:
通过添加以下所有 3 个附加功能，我终于让我的应用程序将语音识别结果限制为指定的语言输入（处理它，例如，日语的“ja”或法语的“fr”）：
String languagePref = "de";//or, whatever iso code...
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, languagePref);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, languagePref);
intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE, languagePref);
Hope this helps someone.
希望这可以帮助某人。

I tried to use
我试着用
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
but it did not work for me (did not take the system language). Helped here like this:
但它对我不起作用（没有采用系统语言）。像这样在这里帮助：
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault().toString());

this code is to set the language in speech recognization
此代码用于设置语音识别中的语言
String languagePref = "te-IN";//this is for telugu
//kannada ---> "kn-IN"
//tamil---> "ta-IN".....
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, languagePref);
