Step #1: "Extract the text in documents". That is up to you, as you are the only person on the planet who knows what "documents" you are referring to.

Step #2: "Convert it to speech" using the text-to-speech engine you linked to above, converting the results into an audio file (see the "File rendering and playback" section).

Step #3: Use MediaPlayer to create your own playback activity with "stop,pause play functions" as you see fit.
