Text to speech, show read words

问题

I am working on an android application to read text, but I need to display the text while it is reading. I have already tried to add words to the TextToSpeech and display the word being read, as I show in the following code, but the fluency is not good when you order to read word by word compared to a complete sentence.

String[] list = {"My", "name", "is", "John"};
TextToSpeech tts = new TextToSpeech(this, this);
tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {
        @Override
        public void onStart(String utteranceId) {
                textView.append(" " + list[k++]);
        }
        @Override
        public void onDone(String utteranceId) {
        }
        @Override
        public void onError(String utteranceId) {
        }
    });

... in the read order

for (String t: list){
    tts.speak(t, TextToSpeech.QUEUE_ADD, null, "ID");
}

So, what I need is to order reading a complete sentence and to display the words that are being read one by one.
