PDF app that uses device's built in TTS

I needed an app that can open PDF files as it is and also use the Text to speech service of the device built in. I downloaded some but results does not match my requirement. Like Voxdox: uses online TTS, PDF reader by Pickwick : lists TTS as feature but not found in app, ezPDF: Open PDF better but uses their TTS never allows device's TTS to speak, @Voice aloud: Allows devices TTS to speak but open "texts only" from the PDF file. And Adobe acrobat: no option of TTS. Please suggest me a better app. Thanks.

TTS: Text to speech.
