孟加拉语内容的TTS在我的Nexus 5X上运行良好，但其他手机不行。在另一个，即三星手机只能说英语单词，但跳过（不讲）孟加拉语单词。
有谁能找到这类问题，请帮助我。
谢谢
代码：

@Override
    public void onInit(int i) {
        if (i == TextToSpeech.SUCCESS) {

        int result = mTextToSpeech.setLanguage(new Locale("bn_IN"));//https://stackoverflow.com/questions/7973023/what-is-the-list-of-supported-languages-locales-on-android

        floatRead.setImageResource(R.drawable.ic_volume_off);

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.i("TTS", "This Language is not supported");
            AppApplication.getInstance().showToast("This Language is not supported");
        }
        read(mNewsDetails.title, true);
        read(mNewsDetails.plain_text, false);

    } else {
        floatRead.setImageResource(R.drawable.ic_read);
    }
    }

void read(String text, boolean flush) {
        if (flush == true) {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP)
                mTextToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
            else
                mTextToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
        } else {
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP)
                mTextToSpeech.speak(text, TextToSpeech.QUEUE_ADD, null, null);
            else
                mTextToSpeech.speak(text, TextToSpeech.QUEUE_ADD, null);
        }
    }
