无法将印地语设置为 texttospeech 的语音语言，即使我的移动 tts 引擎完全支持印地语 textospeech

Unable to set hindi as speech language of texttospeech even though My mobile tts engine fully supports hindi textospeech

        if(t1.isLanguageAvailable(new Locale("hi_IN"))==TextToSpeech.LANG_AVAILABLE)
            t1.setLanguage(new Locale ("hi_IN"));
        else
            Toast.makeText(getApplicationContext(), "Sorry! Text To Speech failed...", Toast.LENGTH_LONG).show();

推荐答案

创建TextToSpeech 类的对象后，需要将其配置(或检查其可用状态/值)到TextToSpeech.OnInitListener 的 onInit() 回调.您将在那里获得有关 TextToSpeech 对象的可靠信息.

After creating an object of TextToSpeech class, you need to configure it (or check it's available state/values) into TextToSpeech.OnInitListener's onInit() callback. You will get reliable information there about your TextToSpeech object.

private fun initTextToSpeech(){
    tts = TextToSpeech(this,this) // TextToSpeech(context,listener)
}

override fun onInit(status: Int) {
    Log.e(TAG, "onInit: status: $status")
    if(status!=TextToSpeech.SUCCESS)return

    val locale = Locale("hi","IN")

    val isLangCountryAvailable = tts.isLanguageAvailable(locale)
    Log.e(TAG, "onInit: isLangCountryAvailable: $isLangCountryAvailable")

    if(isLangCountryAvailable==TextToSpeech.LANG_COUNTRY_AVAILABLE) {
        val setLanguageResult = tts.setLanguage(locale)
        Log.e(TAG, "onInit: setLanguageResult: $setLanguageResult")
    }

    Log.e(TAG, "onInit: availableLanguages: ${tts.availableLanguages}")
    Log.e(TAG, "onInit: voice: ${tts.voice}")

    binding.btnSpeak.isEnabled = status==TextToSpeech.SUCCESS
}

我在上面获得的日志 onInit 回调:
