可用语言的语音识别

问题描述：

从我读过，语音识别可用于3种语言：英语（英国，美国，金..），日本和中国（北京话）

From what I've read, speech recognition is available for 3 languages: English (UK, US, Au ..), Japanese and Chinese (Mandarin).

有谁知道如何把这些语言之间切换的详细信息？有没有办法知道的（编程），它的语言是激活语音识别某个设备上？（也许在日本只有日本...但我可以以某种方式获得这些信息......就像一个属性或什么吗？）。

Does anyone know more details about how to switch between these languages? Is there a way to know (programatically) which language is active for speech recognition on a certain device? (maybe in Japan the only have Japanese ... but can I get this information somehow ... like a property or anything?).

任何有关这将是AP preciated帮助。

Any help regarding this will be appreciated.

谢谢你们。

答

要语言之间进行切换，只需使用你想要的语言并设定 Locale.toString 的语言环境 EXTRA_LANGAUGE 在你 ACTION_RECOGNIZE_SPEECH 意图。

To switch between languages, just use the Locale you want for the language and set Locale.toString for EXTRA_LANGAUGE in you ACTION_RECOGNIZE_SPEECH intent.

要检查哪些语言可供选择，你需要的东西是这样的：

To check what languages are available, you need something like this:

    Intent detailsIntent = new Intent(
            RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
    LanguageDetailsChecker checker = new LanguageDetailsChecker();
    sendOrderedBroadcast(detailsIntent, null, checker, null,
            Activity.RESULT_OK, null, null);

在哪里LanguageDetailsChecker是定义为这样的一个BroadcastReceiver：

Where LanguageDetailsChecker is a BroadcastReceiver defined as something like this:

public class LanguageDetailsChecker extends BroadcastReceiver {

    private static final String TAG = "LanguageDetailsChecker";

    private List<String> supportedLanguages;

    private String languagePreference;

    public LanguageDetailsChecker() {
        supportedLanguages = new ArrayList<String>();
    }

    @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);
        }
    }
}

这一切，code是这个项目。
