如何在Android中的TextToSpeech中为句子设置和说多种语言？

Question

我正在Android中开发TextToSpeech。我使用以下代码，它工作正常。

public void EnableTextToSpeech(){
        //TextToSpeech
        text_to_speech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if(status == TextToSpeech.SUCCESS){
                    Log.d(TAG,"TextToSpeech init SUCCESS");
                    int result = text_to_speech.setLanguage(Locale.US);
                    text_to_speech.setPitch(1);
                    text_to_speech.setSpeechRate(1);

                    if(result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED){
                        Log.d(TAG,"TextToSpeech NOT SUPPORT");
                    }else {
                        Log.d(TAG,"TextToSpeech Enable");
                            String welcome = "Welcome";
                            text_to_speech.speak(welcome , TextToSpeech.QUEUE_FLUSH,null,"TEST");
                    }
                }else {
                    Log.d(TAG,"TextToSpeech init FAIL");
                }
            }
        });
    }

但是我想用一句话来说多种语言，如中文和英文。

我可以设置与以下代码不同的语言吗？

text_to_speech.setLanguage(Locale.CHINESE);
text_to_speech.setLanguage(Locale.US);
