TextToSpeech无法说出大声的声音

Question

我正在尝试使用TTS朗读整个圣经章节。问题是，它失败了，因为文本长度很大。

  textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                int ttsLang = textToSpeech.setLanguage(Locale.US);

                if (ttsLang == TextToSpeech.LANG_MISSING_DATA
                        || ttsLang == TextToSpeech.LANG_NOT_SUPPORTED) {
                    Log.e("TTS", "The Language is not supported!");
                } else {
                    Log.i("TTS", "Language Supported.");
                }
                Log.i("TTS", "Initialization success.");
            } else {
                Toast.makeText(getApplicationContext(), "TTS Initialization failed!", Toast.LENGTH_SHORT).show();
            }
        }
    });
}

public void speak(View view) {
    int speechStatus = textToSpeech.speak(data, TextToSpeech.QUEUE_FLUSH, null);
    if (speechStatus == TextToSpeech.ERROR) {
        Toast.makeText(getApplicationContext(), "TTS conversion failure", Toast.LENGTH_SHORT).show();
        Log.e("TTS", "Error in converting Text to Speech!");
    }
}

我该如何解决？

我在日志Log.e("TTS", "Error in converting Text to Speech!");中得到了
