pdf, word, text to speech

[viivin]

Hi,
I have htc one s and I could listen to my pdf, word files through text to speech apps (google or svox). I reset my phone to factory setting and
now I cannot use text to speech. The google text to speech, svox and voices are installed, but NADA! I googled a lot, and got nothing. please lead me through, step by step so I can use this feature and listen to the files downloaded in the phone.

Thanks in advance,
Viivin
