獲取可用於文本到語音的語言環境（TTS）

我正在研究flashcard程序的文本到語音實現。應該讀出不同語言的文本。爲了正確地做到這一點，用戶必須選擇要閱讀的文本的語言（稍後將被存儲和使用而沒有問題）。獲取可用於文本到語音的語言環境（TTS）

是否有可能在Android系統上獲得可用的TTS語言？如果沒有，是否有可能獲得系統上所有可用的語言環境？

我想，我知道了：getAvailableLocales()和tts.isLocaleAvailable(locale)

您可以使用以下功能的設備的所有可用的語言環境。

Locale loc = new Locale("en"); 
Log.i("-------------",Arrays.toString(loc.getAvailableLocales()));

輸出

根據文檔http://developer.android.com/reference/java/util/Locale.html#getAvailableLocales%28%29 getAvailableLocales（）是靜態的，因此不需要創建Locale對象。使用「Locale.getAvailableLocales（）」是使用此方法的適當方式。 – JonnyBoy 2012-06-28 17:22:33

它以其他方式幫助我。謝謝。 – 2013-10-09 14:02:22

別人已經做的辛勤工作，在http://kaviddiss.com/2012/08/12/android-text-to-speech-languages/

爲了節省您的時間，這裏是他們的代碼片段

TextToSpeech tts = ... 
// let's assume tts is already inited at this point: 
Locale[] locales = Locale.getAvailableLocales(); 
List<Locale> localeList = new ArrayList<Locale>(); 
for (Locale locale : locales) { 
    int res = tts.isLanguageAvailable(locale); 
    if (res == TextToSpeech.LANG_COUNTRY_AVAILABLE) { 
     localeList.add(locale); 
    } 
} 
// at this point the localeList object will contain 
// all available languages for Text to Speech

結果取決於在其上選擇了TTS引擎。例如，我的一部手機包括Pico-TTS和Google文本到語音引擎。

Q-智能（越南手機與谷歌TTS作爲選擇的發動機）

D/SpeakRepeatedly(3979): Engine Google Text-to-speech Engine:com.google.android.tts 
D/SpeakRepeatedly(3979): Engine Pico TTS:com.svox.pico 
D/SpeakRepeatedly(3979): German (Germany):German:de_DE 
D/SpeakRepeatedly(3979): English (United Kingdom):English:en_GB 
D/SpeakRepeatedly(3979): English (United States):English:en_US 
D/SpeakRepeatedly(3979): English (United States,Computer):English:en_US_POSIX 
D/SpeakRepeatedly(3979): Spanish (Spain):Spanish:es_ES 
D/SpeakRepeatedly(3979): French (France):French:fr_FR 
D/SpeakRepeatedly(3979): Italian (Italy):Italian:it_IT 
D/SpeakRepeatedly(3979): Portuguese (Brazil):Portuguese:pt_BR 
D/SpeakRepeatedly(3979): Portuguese (Portugal):Portuguese:pt_PT

而且隨着微微選擇

D/SpeakRepeatedly(4837): Engine Google Text-to-speech Engine:com.google.android.tts 
D/SpeakRepeatedly(4837): Engine Pico TTS:com.svox.pico 
D/SpeakRepeatedly(4837): German (Germany):German:de_DE 
D/SpeakRepeatedly(4837): English (United Kingdom):English:en_GB 
D/SpeakRepeatedly(4837): English (United States):English:en_US 
D/SpeakRepeatedly(4837): English (United States,Computer):English:en_US_POSIX 
D/SpeakRepeatedly(4837): Spanish (Spain):Spanish:es_ES 
D/SpeakRepeatedly(4837): French (France):French:fr_FR 
D/SpeakRepeatedly(4837): Italian (Italy):Italian:it_IT

注：葡萄牙沒有在TTS設置UI上市。當我在我的應用程序中以編程方式選擇葡萄牙語時，它會說葡萄牙語口音！ FWIW這裏是我的代碼選擇葡萄牙語（它接受巴西和葡萄牙語區域設置）。

if (locale.getDisplayName().startsWith("Portuguese")) { 
    Log.i(SPEAK_REPEATEDLY, "Setting Locale to: " + locale.toString()); 
    tts.setLanguage(locale); 
    } 
}

由於不同的TTS引擎isLanguageAvailable返回不同的結果，我發現以下解決方案最上幾種常見的TTS引擎。

另請注意，從Android Lollipop開始，在TextToSpeech中有一個簡單的方法，名爲getAvailableLanguages，它很容易爲您（如果設備運行API 21或更高版本）執行此操作。

您需要在OnInitListener的onInit方法中指定TextToSpeech對象的方法調用以下方法。

ArrayList<Locale> languages; 
TextToSpeech initTTS; 

private void initSupportedLanguagesLollipop() 
{ 
    Set<Locale> availableLocales = initTTS.getAvailableLanguages(); 
    for (Locale locale : availableLocales) 
    { 
     languages.add(locale); 
    } 
} 

private void initSupportedLanguagesLegacy() 
{ 
    Locale[] allLocales = Locale.getAvailableLocales(); 
    for (Locale locale : allLocales) 
    { 
     try 
     { 
      int res = initTTS.isLanguageAvailable(locale); 
      boolean hasVariant = (null != locale.getVariant() && locale.getVariant().length() > 0); 
      boolean hasCountry = (null != locale.getCountry() && locale.getCountry().length() > 0); 

      boolean isLocaleSupported = 
        false == hasVariant && false == hasCountry && res == TextToSpeech.LANG_AVAILABLE || 
        false == hasVariant && true == hasCountry && res == TextToSpeech.LANG_COUNTRY_AVAILABLE || 
        res == TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE; 

      Log.d(TAG, "TextToSpeech Engine isLanguageAvailable " + locale + " (supported=" + isLocaleSupported + ",res=" + res + ", country=" + locale.getCountry() + ", variant=" + locale.getVariant() + ")"); 

      if (true == isLocaleSupported) 
      { 
       languages.add(locale); 
      } 
     } 
     catch (Exception ex) 
     { 
      Log.e(TAG, "Error checking if language is available for TTS (locale=" + locale +"): " + ex.getClass().getSimpleName() + "-" + ex.getMessage()); 
     } 
    } 
}

在Android 5.0（API級21）開始，TextToSpeech.getAvailableLanguages已被添加到提取一組由TTS引擎所支持的所有語言環境。

TextToSpeech tts;    // assume this is initialized 
tts.getAvailableLanguages(); // returns a set of available locales

我也注意到，由TextToSpeech.getAvailableLanguages返回的Locale集合可能不是的Locale.getAvailableLocales嚴格的子集，即有可能是由不被系統支持TTS引擎所支持的語言環境。
